<?xml version="1.0" encoding="utf-8"?>
<photogallery ID="8" name="Residential">
	<album ID="5" name="Leb" photogallery="Residential" date="29/10/2008" location="Lebanon" architecture="Roman" img="thumbnail_1245677486.jpg">
		<picture ID="Leb" path="thumbnail_1245670921"/>
	</album>
	<album ID="6" name="Leb" photogallery="Residential" date="29/10/2008" location="Lebanon" architecture="Roman" img="thumbnail_1245677486.jpg"/>
		<picture ID="Leb" path="thumbnail_1245670921"/>
		<picture ID="Leb" path="thumbnail_1245670921"/>
	</album>
	<album ID="7" name="Leb" photogallery="Residential" date="29/10/2008" location="Lebanon" architecture="Roman"/>
		<picture ID="Leb" path="thumbnail_1245670921"/>
		<picture ID="Leb" path="thumbnail_1245670921"/>
		<picture ID="Leb" path="thumbnail_1245670921"/>
	<album ID="8" name="Allo" photogallery="Residential" date="2/7/1975" location="Alll" architecture="Lol">
		<picture ID="Allo" path="thumbnail_1245658288"/>
		<picture ID="Allo" path="thumbnail_1245658288"/>
		<picture ID="Allo" path="thumbnail_1245658288"/>
		<picture ID="Allo" path="thumbnail_1245673276"/>
	</album>
</photogallery>

i need to get the pictures of a specific album.
i got managed a way to get to my specific album, but the problem is that im not able to get only this album children! can i do it in php? or i have to use javascript!?
this is my php code

<?php
	$albid=$_GET['ID'];
	
$xmlFile = new DOMDocument();
$xmlFile->load("Residential.xml");

$xml_album = $xmlFile->getElementsByTagName("album");
	$i = 0;
		while ($xml_album->item($i)->getAttribute('ID') != $albid)
				{
					$i += 1;
				}		
				$album = $xml_album->item($i); 
				echo ("pictures in this album are:");//my problem:D
				
				
	?>

So it doesn't matter which language represents the XML document as DOM, it will have the same structure and methods defined by the DOM Specs.

Use var_dump() and get_class_methods() to find out what methods are available on an object.

For example, on your $album object.

It really helps to use teh functions that give you program state, like:

var_dump(), print_r() get_class_methods(), Reflection etc.

Your XML document is not well-format.

<?php
$albid=$_GET['ID'];
	
$xmlFile = new DOMDocument();
$xmlFile->load("Residential.xml");

$xml_album = $xmlFile->getElementsByTagName("album");
$i = 0;
while ($xml_album->item($i)->getAttribute('ID') != $albid)
  {
	$i += 1;
   }		
  $album = $xml_album->item($i); 
  $children=$album->childNodes;
   foreach($children as $child) {
       if($child->nodeType==XML_ELEMENT_NODE) {
            print "<br/>" . $child->tagName;
            print " ID : " . $child->attributes->item(0)->value;
            print " path : " . $child->attributes->item(1)->value;
      }
   }                 
?>

Note that:

while ($xml_album->item($i)->getAttribute('ID') != $albid)
  {
	$i += 1;
   }

can will trigger an error if $albid doesn't have a corresponding value in the XML doc.

a better alternative is:

while ($xml_album->item($i) && $xml_album->item($i)->getAttribute('ID') != $albid)
  {
	$i += 1;
   }

PHP does lazy evaluation. Meaning if the first evaluation is false:

$xml_album->item($i)

Then it doesn't go on to evaluate

&& $xml_album->item($i)->getAttribute('ID') != $albid

That way you break the loop before an error is triggered. Note that if there was not error triggered, you'd actually go into an infinite loop.

Also good to check if you actually found a corresponding node, otherwise you'd run into more errors:

if ($album = $xml_album->item($i)) {
// do stuff

} else {
// error stuff
}

//for this I made this code 
<?php 

  if(isset($_GET['ev_id'])) 
 {
     $get_event = $_GET['ev_id'];

     $dom = new DomDocument;
     $dom->preserveWhiteSpace = FALSE;
     $xml = file_get_contents("http://localhost/bluesq/clubsq.xml");
     $dom->loadXML($xml);
     $params = $dom->getElementsByTagName('Event'); // Find Sections 
     $i=0;

     while ($params->item($i) && $params->item($i)->getAttribute('ev_id') != $get_event)
     {
         $i += 1;
     }

      $event = $params->item($i); 
      print_r($event);
   }          
?>

In this I didn't get any value in $event.
