XML problem

rallen102

I have been reading Adam Delves article on managing XML files with PHP. I copied the XML into a file, the PHP (DOM) into a new file, and uploaded them to my server. The server reports that DOM is installed and enabled.

When the code gets to $xml->load('library.xml'); it just dies. What am I missing?

Which version of PHP are you using?

rallen102

PHP v4.4.4
DOM/XML enabled
DOM/XML API Version 20020815
libxml Version 20624
HTML Support enabled
XPath Support enabled
XPointer Support enabled
DOM/XSLT enabled
libxslt Version 1.1.16
libxslt compiled against libxml Version 2.6.24
DOM/EXSLT enabled
libexslt Version 1.1.16

Turn on error reporting and see if you get a specific error message...

error_reporting(E_ALL);

rallen102

I added that line to my page but it had no effect.

alimadzi

Did you add it to the top of the script? Sorry that I forgot to clarify that.

rallen102

Yes, it is the first line.

I have simplified the code to this:
<?php
error_reporting(E_ALL);
$xml = new DomDocument();
// $xml->load('library.xml');
?>
<html>
<head>
<title>XML Library</title>
</head>
<body>
<div>
<h2>Book Title</h2>
<p><b>Author:</b>: <?php //echo($author) ?></p>
<p><b>Categories:</b>: <?php //echo($catList) ?></p>
</div>
</body>

</html>

I have verified that the library.xml file is valid and in the same directory as the code.

When I uncomment the load instruction in line 4 the browser displays a blank page.

Can you show us more of your code besides that one line? Are you instantiating a new DOMDocument? Here's some documentation from the PHP site:

http://us2.php.net/manual/en/function.dom-domdocument-load.php

rallen102

I don't see a difference between my code and the documentation sample code.

Just for fun, let's see if loadXML() works. Copy your entire XML file into a variable in your script and load it like they do in this example:

http://us2.php.net/manual/en/function.dom-domdocument-loadxml.php

Trying to narrow down the possibilities as far as what's going wrong with this.

I replaced the top PHP code with:
<?php
error_reporting(E_ALL);
$xml = new DomDocument();
$xmltext = ' <library>

</library>';
$xml->loadXML($xmltext);
?>

I got the same nothing in the browser.

I'm not sure what to tell you. Are you using a hosting company? Maybe they can troubleshoot this for you. Anyone else have ideas?

rallen102

I have no confidence in the hosting company to troubleshoot this. I will build an apache server and play with the PHP compile until I make it work ... or not?

If anyone has a clue, please let me know.

javier_06

I got the exactly same problem, did you find an answer for this?

Thanks.
