  7. Need an xslt to convert xml into json.I have a xml file which is having 3 attributes.The value in the 3rd attribute is another xml file.I need an xslt which can read the value of the 3rd attribute as another xml (not just a value) and can convert it into json format. <?xml version="1.0"?> <ResultSet> <attribute1>123</attribute1> <attribute2>456</attribute2> <attribute3> <?xml version="1.0"?> // Need this xml (i.e. value of third attribute) to be converted into Json <NewResultSet> <rowset> <node1>111</node1> <node2>222</node2> </rowset> <rowset> <node1>333</node1> <node2>444</node2> </rowset> </NewResultSet> </attribute3> </ResultSet>
  8. I have some data in a flat file. These are the fields: nameaddressziplatlng A row of data might look something like: fishing hole #1, Catalina Island U.S., 90704, 33.3, 118.4 There are fifty rows of data. I am trying with PHP to encode this data into an XML file. The ultimate goal is that the data will be stored on the disk in XML format and when requested PHP will read the XML file and retrieve the data and put it into an array so I can encode the data in JSON and send it back off to JavaScript (AJAX). I'm very familiar with working with flat files and SQL however XML is a bit unfamiliar to me as of yet. How would this be accomplished? Good Evening W3Schools!

    Use of json_encode

    <?php$link = mysql_connect('localhost', 'root', '');if (!$link) { die('Connection error: ' . mysql_error());} $result = mysql_query('use `mydatabase`');if(!result) {die('Query error:' . mysql_error());} $result = mysql_query('select * from locations'); mysql_close($link); echo json_encode($result);?> I have a sample I prepared that I am working on to get it functional. I see that in the reference for json_encode that the parameter is not allowed to be of the type resource. This leads to the problem of what to do with $result. I suppose I could use a for loop and populate an array and then pass that array to json_encode. I guess the real reason why I post this is to see if someone has some trick to do this that I may not be aware of. Thoughts?

    JSON trouble

    I'm working on a project that involves fetching a JSON file from Github. I make an AJAX GET request to that page and store the responseText data in localStorage. Later, I need to retrieve the stringified JSON object from localStorage, parse it, and scan it. My trouble right now is the parsing, though. Whenever I use JSON.parse, I get some sort of error...unexpected this, unescaped that. I just can't successfully parse the JSON object. What do I need to know about the JSON syntax so that I can write a parseable JSON file? I don't want my project continually messing up because of these parsing issues.
  12. I've used eval() to turn a JSON array into an object.But people say eval() has security issues. What particular are the issues? Turning scripts as well into JS objects?And how about stringify()? How can I make it work in IE7?
  13. I'm trying to write an algorithm return an array sorted by a given property in a JSON object. Here's an example of what I want to sort: obj_to_be_sorted = {'four' : {'num' : 4},'one' : {'num' : 1},'three' : {'num' : 3},'two' : {'num' : 2}} sort = function(obj, property, reverse_order) { a = [] for (key in obj) { a.push(key) } return a.sort(a, { /* I think it would involve the sort function... */ }} sorted_array = sort(obj_to_be_sorted, 'num', false); // should return the JSON keys sorted by the 'num' property, i.e. ['one', 'two', 'three', 'four'] I just don't know I would go about doing this. I'm thinking it would be only a few lines of code - very simple - but I'm just not good at writing algorithms yet. I would greatly appreciate any assistance you could give me.
  14. var curPic = 0;var fadeTimer;var opacStep = 0.5;var curOpac = 10;var dirn = -1; function autoImage(){ if(fadeTimer){clearInterval(fadeTimer);} fadeTimer = setInterval(setOpacity,100); function setOpacity() { curOpac += opacStep * dirn; if (curOpac < 0){ swapImage(); curOpac = 0; dirn = 1; autoImage(); return; } if (curOpac > 10){ curOpac = 10; clearInterval(fadeTimer); dirn = -1; return; } if (document.getElementById("img").style.opacity=="string"){ document.getElementById("img").style.opacity = curOpac/10; } else { document.getElementById("img").style.filter = 'alpha(opacity=' + curOpac*10 + ')'; document.getElementById("img").style.MozOpacity = curOpac/10; } } function swapImage(){ curPic = (++curPic > images.length-1) ? 0 : curPic; document.getElementById("img").src = images[curPic]; } }window.onload = function(){ autoImage(); } The above works. var slideshow = { images : ["http://www.blogsdna.com/wp-content/uploads/2011/03/Google-labs.png","http://thenextweb.com/socialmedia/files/2010/07/youtube_logo.png","http://www.techlifeweb.com/facebook_logo.jpg","http://scm-l3.technorati.com/10/05/10/12671/twitter-logo-5.jpg","http://www.thetechherald.com/media/images/201115/Adobe_2.jpg","http://www.easyquestion.net/learninginadigitalworld/wp-content/uploads/2009/06/ms-office-logo.jpg"], curOpac: 10, opacStep: 0.5, dirn: -1, setOpacity: function(){ this.curOpac += this.opacStep * this.dirn; if (this.curOpac < 0) { this.swap; this.curOpac = 0; this.dirn = 1; slideshow; return; } if (this.curOpac > 10) { this.curOpac = 10; this.dirn = -1; return; } if (document.getElementById("img").style.opacity=="string"){ document.getElementById("img").style.opacity = this.curOpac/10; } else { document.getElementById("img").style.filter = 'alpha(opacity=' + this.curOpac*10 + ')'; document.getElementById("img").style.MozOpacity = this.curOpac/10; } }, curPic: 0, swap: function(){ this.curPic = (++this.curPic > this.images.length) ? 0 : this.curPic ; document.getElementById("img").src = this.images[this.curPic]; }, };window.onload = function(){ fadeTimer = setInterval(function(){slideshow.setOpacity()},5000); } And I want to use JSON to re-make the slideshow. But it does not work.FF Console reports:
