XML Parser

<?php$file="http://www.URL.com/file.XML";$xml_parser = xml_parser_create();$handle = fopen($file, "rb");$contents = '';while (!feof($handle)) {  $data .= fread($handle, 8192);}fclose($handle);xml_parse_into_struct($xml_parser, $data, $vals, $index);xml_parser_free($xml_parser);$params = array();$level = array();foreach ($vals as $xml_elem) {  if ($xml_elem['type'] == 'open') {   if (array_key_exists('attributes',$xml_elem)) {	 list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);   } else {	 $level[$xml_elem['level']] = $xml_elem['tag'];   }  }  if ($xml_elem['type'] == 'complete') {   $start_level = 1;   $php_stmt = '$params';   while($start_level < $xml_elem['level']) {	 $php_stmt .= '[$level['.$start_level.']]';	 $start_level++;   }   $php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';   eval($php_stmt);  }}echo "<pre>";print_r ($params);echo "</pre>";?>

This code is from http://www.php.net/manual/en/function.xml-...into-struct.phplet this one be the input<?xml version="1.0"?><moldb> <molecule> <name>Alanine</name> <symbol>ala</symbol> <code>A</code> <type>hydrophobic</type> </molecule> <molecule> <name>Lysine</name> <symbol>lys</symbol> <code>K</code> <type>charged</type> </molecule></moldb>The parser not parsing the second <molecule> tag.What should I do to work the code correctly?

WOW. Unless you're using PHP4, I suggest you try out the DOM Functions. They are much easier to set up and debug. Besides, what do you mean by "parse"? With the DOM functions, "parse" would mean "select" but then you'd do something .TIP: Begin with the evaluate() function and after you feel comfortable using XPath, go to query(). Then use item() alongside the rest of the functions to do something with the selected item() from the query() results.

oh that new DOM functions are interesting. I will be trying with these.

I'm trying to parse RSS files. I just want to know is there a function like javascript innerHTML() in PHP$titles = $dom->getElementsByTagName('title');foreach ($titles as $title) { echo $param->.......'<br>'; // I want to get the contents inside <title> tags}

DOM results are not saved as arrays. They are saved as DOM objects you then refer to with item(). Values of properties (in the example below, that's "length") are an exclusion to this rule. They are most often strings instead.Try something like

$titles = $dom->getElementsByTagName('title');for ($i=0; $i<=$titles->length; $i++){echo $titles->item($i) . '<br>';}
