I wonder whether someone may be able to help me please.
I'm using the script below to create a 'gallery' page.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<?php
//This variable specifies relative path to the folder, where the gallery with uploaded files is located.
$galleryPath = 'UploadedFiles/';
$thumbnailsPath = $galleryPath . 'Thumbnails/';
$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR;
$descriptions = new DOMDocument('1.0');
$descriptions->load($absGalleryPath . 'files.xml');
path="files[userid=1]/originalname/folder/description/source/thumbnail";
// code for IE
if (window.ActiveXObject)
{
var nodes=xml.selectNodes(path);
for (i=0;i<nodes.length;i++)
{
document.write(nodes[i].childNodes[0].nodeValue);
}
}
?>

The data for this page comes from the file, 'files.xml', an extract of which can be found below.
<?xml version="1.0" encoding="utf-8" ?>
- <files>
<file name="Test 1/article-0-07D01B74000005DC-138_468x617.jpg" source="article-0-07D01B74000005DC-138_468x617.jpg" size="143110" originalname="article-0-07D01B74000005DC-138_468x617.jpg" thumbnail="article-0-07D01B74000005DC-138_468x617.jpg" description="No description provided" userid="1" locationid="1" folder="Test_1" />
</files>
What I wanted to do is filter the records returned, to be more specific by 'userid' and 'locationid' and for testing purposes these had the value of '1'.
I'd received some useful guidance from this site at XML 'Select Where' Statement, and from the subsequent 'XPath' tutorials I've read I put together what I thought would be the correct xpath code to use which is at the top of my 'gallery' page script.
However, when I've tried to run this I recieve the following error:
Parse error: syntax error, unexpected '=' in /homepages/2/d333603417/htdocs/development/gallery.php on line 16
It's clear that the problem is with the 'equals', but when I've gone back to the tutorials, this appears to be the correct syntax to use.
I just wondered whether someone could perhaps have a look at this please and let me know where I've gone wrong.
Many thanks
