PHP + XML = Parsing

[businessman332211@hotmail.com]

Ok, I went through about 8 tutorials, and got something together. When I had a bunch of error's I didn't understand what was going on, after a lot of reading and lot of tutorials I was able to form something that works, atleast for basic parsing.The situation is a little hard to explain, I have a client getting xml file's from zap2it and he saved them on his server daily. The main file is menu.xml, everything with it is already taken care of. In menu.xml it has information on all the television channels. Then each channel has there own xml file's that get updated daily. I needed a way to run through those, pick out the show's that are currently playing, and display them on the screen. The script I ahve so far, is doing a pretty good job of setting up the groundwork for what I want to do, but it's just not coming together, mostly because I don't know how to advance. After a lot of work, I was able to remove all errors, which helped, and it works. However I don't know what to do from here, to get what I want done.Each channel is in a seperate page, here is some example coding, that a channel might contain:

<programme start="20070129140000 -0500" stop="20070129150000 -0500" channel="I44228.labs.zap2it.com">	<title lang="en">mtvU Video Hour</title>	<category lang="en">Music</category>	<category lang="en">Series</category>	<episode-num system="dd_progid">SH684893.0000</episode-num>Start File  </programme>  <programme start="20070129150000 -0500" stop="20070129160000 -0500" channel="I44228.labs.zap2it.com">	<title lang="en">mtvU Video Hour</title>	<category lang="en">Music</category>	<category lang="en">Series</category>	<episode-num system="dd_progid">SH684893.0000</episode-num>  </programme>  <programme start="20070129160000 -0500" stop="20070129170000 -0500" channel="I44228.labs.zap2it.com">	<title lang="en">BFOC Student Film of the Week</title>	<sub-title lang="en">Urban Shogun</sub-title>	<date>20070126</date>	<category lang="en">Art</category>	<category lang="en">Limited Series</category>	<episode-num system="dd_progid">EP895481.0001</episode-num>	<episode-num system="onscreen">101</episode-num>  </programme>

There are a total of 100+ channel specific xml file's I have to work through.The current setup I have is meant to run through all of them, as I have all the file name's saved in an array. here is my code, and below is a few questions, I just couldn't make progress on.

<?php// Build an array with all the channel names.$channels = array ("I11187",				   "I11829",				   "I11269",				   "I11768",				   "I11993",				   "I19556",				   "I11490",				   "I11479",				   "I11959",				   "I23319",				   "I18774",				   "I11287",				   "I12553",				   "I24634",				   "I23324",				   "I22564",				   "I23327",				   "I23328",				   "I23329",				   "I10240",				   "I10244",				   "I10241",				   "I18429",				   "I16585",				   "I24553",				   "I10243",				   "I10021",				   "I12852",				   "I16374",				   "I10142",				   "I10145",				   "I10139",				   "I10161",				   "I10162",				   "I10035",				   "I10057",				   "I10051",				   "I10153",				   "I11097",				   "I11163",				   "I11164",				   "I11207",				   "I10149",				   "I10989",				   "I14321",				   "I14909",				   "I10918",				   "I16409",				   "I45654",				   "I10179",				   "I12444",				   "I16485",				   "I12410",				   "I14899",				   "I14776",				   "I16011",				   "I20789",				   "I10986",				   "I16361",				   "I10138",				   "I11218",				   "I44228",				   "I11180",				   "I16331",				   "I11150",				   "I16615",				   "I18327",				   "I16617",				   "I16618",				   "I18284",				   "I16616",				   "I18544",				   "I18179",				   "I11158",				   "I14902",				   "I14771",				   "I12574",				   "I26784",				   "I10093",				   "I12131",				   "I10171",				   "I11006",				   "I16123",				   "I30103",				   "I21450",				   "I19059",				   "I18332",				   "I25354",				   "I31634",				   "I19283",				   "I18644",				   "I21852",				   "I21063",				   "I24935",				   "I24248",				   "I29323",				   "I28452",				   "I12324",				   "I16345",				   "I10239",				   "I11118",				   "I15377",				   "I27773",				   "I19247",				   "I18715",				   "I19979",				   "I25238");				   // Build the file name's dynamically based on the above file names.// register empty array to hold the upcoming information$files = array();// run through all the channels, assining there full file names into an arrayforeach ($channels as $k) {	$files[] = $k .

1. This doesn't seem to cycle through all documents. It does 1, then says at the very bottom (out of nowhere) "Start Filejunk after document element77" Why is this?2. Is it possible to cycle through all xml file's using this foreach3. How do I tell it to look for something specific, I need it to do the following* Go into file 1* Go through each set of programme tag's, check the starttime/stoptime with some calculations to see which one would currently be playing. * When it finds one in file one that is currently playing, throw it in an array, and move onto the next file* Repeat for all the rest of the file's.This is what I am wanting to do, but don't know how to put it together, any guidance based on my above code, would be greatly appreciated. I have done all I can myself, and now I am running around in circles trying to find out what's next.

Ok, I have discovered some things. For one, I looked at my previous question, I figured that out.I am 100% amazed at the power of the Expat library. I dug into it, and got a skeleton that actually worked, and did some playing with it, so I was able to single out a couple of specific questions, I need some advice on. Here is my code for example.Example XML File

Notes* There are a total of 100+ files* I need to run through them in a foreachI am not to that step, and I am trying to do something else (get an understanding of how the basic structure works)I understand this, but here are my questions.1. I understand how to set a foreach for the start tag, and do what is necessary for that, how does the start tag, understand what is happening on the data. I don't understand there relationship.For example, I need to tell it at the start tag, to do this, this, and this to the data. How do I tell it to do that, since the data function is seperate?2. I need to find the starttime/stoptime of each programmer. Even when I dump all the data, the start/stop time doesn't come up. How do I, or what can I change with my code, to give me access to that information so I can test the proper calculations?3. I don't understand what is happening when I put it in a foreach. Doing it this way I have something to work with. However when I throw a foreach around it using the file names in the array, it doesn't work. It goes through file one, starts up the second file, and put's out a message that says everything else is junk (something php throws out), then stops anything else from happening. How can I get a foreach loop to work around this once I get it doing exactly what I want on the first file?Thank you for the help.

I revised some of my code, and made some changes, but there are still a few things I don't understand.That helps me to find the program tag.However the programme has 2 attributes <programme start="20070128230000 -0500" stop="20070129003000 -0500" channel="I45654.labs.zap2it.com">I need to also check the start/stop each time around.I need to do calculations, then when it finds one that matches what would be what is currently playing, I need it to get the title, adn sub-title. And save it in an array, so I can get to it later.below is what my new code looks like, after some more reading.

<?php// Build an array with all the channel names.$channels = array ("I11187",				   "I11829",				   "I11269",				   "I11768",				   "I11993",				   "I19556",				   "I11490",				   "I11479",				   "I11959",				   "I23319",				   "I18774",				   "I11287",				   "I12553",				   "I24634",				   "I23324",				   "I22564",				   "I23327",				   "I23328",				   "I23329",				   "I10240",				   "I10244",				   "I10241",				   "I18429",				   "I16585",				   "I24553",				   "I10243",				   "I10021",				   "I12852",				   "I16374",				   "I10142",				   "I10145",				   "I10139",				   "I10161",				   "I10162",				   "I10035",				   "I10057",				   "I10051",				   "I10153",				   "I11097",				   "I11163",				   "I11164",				   "I11207",				   "I10149",				   "I10989",				   "I14321",				   "I14909",				   "I10918",				   "I16409",				   "I45654",				   "I10179",				   "I12444",				   "I16485",				   "I12410",				   "I14899",				   "I14776",				   "I16011",				   "I20789",				   "I10986",				   "I16361",				   "I10138",				   "I11218",				   "I44228",				   "I11180",				   "I16331",				   "I11150",				   "I16615",				   "I18327",				   "I16617",				   "I16618",				   "I18284",				   "I16616",				   "I18544",				   "I18179",				   "I11158",				   "I14902",				   "I14771",				   "I12574",				   "I26784",				   "I10093",				   "I12131",				   "I10171",				   "I11006",				   "I16123",				   "I30103",				   "I21450",				   "I19059",				   "I18332",				   "I25354",				   "I31634",				   "I19283",				   "I18644",				   "I21852",				   "I21063",				   "I24935",				   "I24248",				   "I29323",				   "I28452",				   "I12324",				   "I16345",				   "I10239",				   "I11118",				   "I15377",				   "I27773",				   "I19247",				   "I18715",				   "I19979",				   "I25238");				   // Build the file name's dynamically based on the above file names.// register empty array to hold the upcoming information$files = array();// run through all the channels, assining there full file names into an arrayforeach ($channels as $k) {	$files[] = $k .

What are you having problems with at this point? I haven't done hardly anything with XML parsing, but if there are some problems you need help with I'll do what I can.

THANK YOU, I have been trying to get help on this forever. I know somebody would pay attention to me. Yes there is something I need to figure out, I have the whole script done up to a point.Here is my current code.Based on the layout of the xml file's shown aboveHere is my current program

I have figured out a lot,w hen you pass the functions to the xml functions, it run's through them one at a time.I need to figure out one thing right now.When it come's in contact with that specific tag (the programme tag), I need to take the start/stop time's and calculate what is currently playing, I am clueless from this point.Some direction, any direction would be helpful at this stage.

[justsomeguy]

Are you able to get the attribute values at this point? If you can get the values for start and stop, it would be fairly easy to figure out what time it is now, and so what is currently playing. But, not being familiar with the XML parser in PHP, I'm not exactly sure what all the code above is doing.

[businessman332211@hotmail.com]

// Functions To go into the element handlers, later on// variables to pass to user functions// function to start searchingfunction startElement($parser, $name, $attrs='') {global $open_tags;$current_tag = $name;if ($format = $open_tags[$name]){switch($name){case 'programme':$a = "0";break;default:break;}}}// function to end searchingfunction endElement($parser, $name, $attrs='') {global $close_tags;if ($format = $close_tags[$name]){switch($name){case 'programme':$a = "1";break;}}}// function to take data from tagsfunction tagData($parser, $data) {global $current_tagswitch($current_tag){case 'programme':echo('<h1>This is the article</h1>');break;case 'articleName':echo('<h2>'.$data.'</h2>');break;case 'author':echo('<h3>By: '.$data.'</h3>');break;case 'date':echo('<h3>On: '.$data.'</h3>');break;case 'articleBody':echo('<p>On: '.$data.'</p>');break;}}}// set variables (tags)$open_tags = array("programme" => "<programme>","title" => "<title>","sub-title" => "<sub-title>");$close_tags = array("programme" => "</programme>","title" => "</title>","sub-title" => "</sub-title>");$nowplaying = array(); // array to trap what is currently playingxml_set_element_handler($parser, "startElement", "endElement");xml_set_character_data_handler($parser, "tagData");

These are the things I don't understand1. How to work with the attributes.I found some good tutorials on this before, but now, I have run out of possible tutorial's, it's making it pretty hard.

[justsomeguy]

When you set up the tagData handler, and it gets called, what is in the $data parameter? Print out the $data variable in the tagData function and see if that is the attribute list or what it is.

[businessman332211@hotmail.com]

That code there probably doesn't work fully, I made some changes to it, when I change it back, the data is the data in between the tag's.What it does is run through the xml until it get's to the first open element, it runs the open function, then it takes care of finding the ending element, and loads the ending funciton, then loads the data function to handle data in between. starts at the next element and cycles through them again, I know how to feed it end tag's, start tag's, how to get the data. However I don't know how to factor in attributes, or how to format them when I put them in.

[justsomeguy]

According to the documentation for xml_set_element_handler, the attribute list gets passed to the start_element_handler function as an array. So you have access to all of the attributes and their values in that function.

function startElement($parser, $name, $attrs) {  global $open_tags;    $current_tag = $name; //this variable doesn't get used anywhere else  if ($format = $open_tags[$name]) //why are you using $format? what is the purpose of this if statement?  {	switch($name)	{	  case 'programme':		$a = "0";		echo "attribute list for programme:<br>";		foreach ($attrs as $a_name => $a_val)		{		  echo "{$a_name}=\"{$a_val}\"<br>";		}		break;	  default:		break;	}  }}

Ok, the top 2 arrays aren't being used yet. I need to later be able to run through all xml file's and save the currently playing program into an array. For now I just want to do one xml file, to get the currently playing program from that file, so I can then replicate it to get the other's.In this programming code above, $current_tag = $name is used later on to tell the data handling function which tag it's talking about. SInce it run's through them, trapping that in a variable, then later tells the other function, we are working with data in between those 2 tag's.THat is what I formulated based on the tutorials.As for format, I am not sure, just something else I got together using the tutorials. I just still don't udnerstand how the whole thing works. The 2 questions I haveIs where to do the calculations, do I just put it in between what i currently have like this

function startElement($parser, $name, $attrs){  global $open_tags;    $current_tag = $name; //this variable doesn't get used anywhere else  if ($format = $open_tags[$name]) //why are you using $format? what is the purpose of this if statement?  {	switch($name)	{	  case 'programme':		$a = "0";		echo "attribute list for programme:<br>";		foreach ($attrs as $a_name => $a_val)		{		  // do date calculations, on the start time and start date. 		 // which in this context, should be saved in a_name as start and stop I guess		// see that is the part I don't understand.		}		break;	  default:		break;	}  }}

What is bad, is I need to replciate this code after I start pulling the now playing, and then setup a foreach so it will do it for each xml file. This is getting really deep, that is why I needed some expertise, but it's hard finding someone willing to lend a hand with something related to xml parsing, everyone i tried knew nothing about it, and the one's that did, didn't feel like explaining anything. I am slowing hacking away at it, day by day. After studying xml/php parsing all weekend, I finally made some progress on monday, each day I get a little further and understand a little more, but this whole Expat library is hard to come to grip's with.Thanks for any feedback.

The startElement function is the only one that has access to the attribute list, so anything you need to do with the attributes, you need to do there. The tagData function is the function that has access to the contents of the element, so again, anything you need to do with the element contents would need to be done there. If you run the code I posted above, you should see the names and values of each attribute printed out. The $attrs array is an associative array containing all of the attribute names and values.array("start" => "<start time>", "stop" => "<stop time>", "channel" => "<channel url>");

Ok, based on what you said I am goign to study some more tonight.Tomorrow I will try to pull all this together in my program, maybe you can help me out again if I get stuck, I knew I could count on you, everytime I have really needed help you were there to give me guidance.Thanks so far, for the help, let me soak some of this in, and put together what I can.

Ok, I have done massive amounts of more studying last night, then came today, made some corrections, fixes, and tried out some of what you said.Yes the attribute is saved in that array, so I can access them via $att['START']$att['STOP']I can get access to them using this method.Now, I have created the above code, but it still is not working. I am simply trying to identify the location of the start time, and start time so I can know I can find it, then from there, find out how to get the title/subtitle of what was currently playing, and save it in an array. However it's not returning anything, I know the currently playing programme is in each xml file, it's not telling me after checking through this xml file, that one of them is now playing, again below is an example of the entire xml file (They are all the same, but in this case, I am putting the one I am actively working with.Any advice would be greatly appreciated.

$time = strftime("%Y%m%d%H%M");function startElement($parser, $name, $att='') {	global $open_tags;	global $current_tag;	$current_tag = $name;		if ($att['START'] < $time && $att['STOP'] > $time) {			echo "Got you";		}

The function doesn't have access to the time variable, it is not declared as global in the function. Also, you leave the seconds off the time string but they are included in the XML, so your time string will always be numerically less (2 orders of magnitude) then the XML timestamp. You will also probably need to do some converting and massage the XML timestamp a little. Since it has the time zone, you may need to normalize both timestamps to the same time zone, unless the server is also in GMT -5. But you will want to strip the time zone off the XML timestamp (you could explode on a space and use the first element as the timestamp), and then convert both the XML timestamp and your timestring to integers before you compare them.

Perfect, that step is completed. Thanks. There are 2 more things I need to figure out, the last one I should be able to handle.Now that I have this working (thanks to you), how do I get it to recognice the title/subtitle/time of the current playing show.Now, I am having this problem, when I put it here, it says got you, when I put it inside the switch for programme, nothing. I need to figure out how to specify by start and stop, which program it's on, so I can capture the start time, stop time, title, and subtitle all inside an array. That is the next step, any guidance is appreciated, or pointing me in the right direction. Thanks.

I would think you would access the other elements, like title and description, the same way. The startElement function would be called when it found <title>, and then the tagData function would be called with the contents of the title element.

[businessman332211@hotmail.com]

I more of mean, I just don't understand the process. Right now I have the start element echoing got you when a match is found. If I try echoing the data there, in the other, it doesn't echo.

<?php$time = strftime("%Y%m%d%H%M%S%");function startElement($parser, $name, $att='') {	global $time;	global $open_tags;	global $current_tag;	$current_tag = $name;	$start = strftime($att['START']);	$stop = strftime($att['STOP']);	if ($start < $time && $stop > $time) {		}	if ($format = $open_tags[$name]){        switch($name){            case 'PROGRAMME':            break;        }    }}?>

The function above is where I am testing it at, it find's it appropriately if possible. It prints got you to the screen, so I know it found a match. If I then try to echo data down there, it doesn't echo the data.Nothing seems to be working, I tried making the stop start, and attributes global, then doing the same calculations for date. I am a little confused on what is next. I have also tried echoing out the data in that function it come's up blank. I am a little confused, if I just echo out the data in the data handler function it echo's out all the data in between all tags. I don't understand what it's doing.

[justsomeguy]

For every element it encounters, it calls the startElement function, then the tagData function, then the endElement function. startElement gets the element name and attributes, tagData gets the data in the element, and endElement gets the element name again. Replace your functions with these to see what is going on:

function startElement($parser, $name, $attrs){  echo "<b>startElement called:</b><br>";  echo " name: {$name}<br>";  echo " attributes:<br>";  foreach ($attrs as $n => $v)  {	echo " {$n}={$v}<br>";  }  echo "<hr>";}function endElement($parser, $name){  echo "<b>endElement called:</b><br>";  echo " name: {$name}<br>";  echo "<hr>";}function tagData($parser, $data){  echo "<b>tagData called:</b><br>";  echo " data: {$data}<br>";  echo "<hr>";}

[businessman332211@hotmail.com]

I see what it output's yes. i understand that part, it's just I am tellign the start handler to find the range that is current. When it find's a match it tell's me what is going on. However if I go to data, I still don't understand how to make it do something like get the data, or something else, when a match is found in the first function.

[justsomeguy]

It will get the data regardless of if a match is found. You may want to have a global flag that you set in the start function, and check it in the data function to see if there was a match.
