DOMDocument error 1

[richardko]

Hi,
I am trying to use the php5 's DOM extension but i am getting error.
The code I am trying to execute is:

<?php
$dom = new DOMDocument;
$dom->load("book.xml");
print "<pre>";
print $dom->documentElement->nodeName;
print "<br/>\n";
//does not work...
//print $dom->getElementsByTagName("book")[0];

print_r( $dom->getElementsByTagName("book"));
print "<br/>\n";

print htmlentities($dom->saveXML());
?>


This is an example I found. It gives error:
PHP Fatal error: Class 'DOMDocument' not found in /home/test.php on line 2

Any idea?
I am using php 5.0. Here is version output:

PHP 5.1.6 (cli) (built: Dec 15 2006 10:43:55)
Copyright (c) 1997-2006 The PHP Group

It may make a difference on what platform you're running PHP and how you installed it. This page at CodeWalkers mentions, for example, that the PHP package that comes the Fedora Core 4 has DOM turned off.

If you look at the output of a script that reads:

<?php
phpinfo();
>?

does that output mention DOM?

Thanks for the reply.
You were right, DOM was turned off. Do i need to recompile php to use DOM?

 

[sleipnir214]

I would, but I usually install PHP from source code every time anyway. That page I linked to at CodeWalkers talks about additional PHP packages that might enable the additional functionality.

thanks for the quick replay again.
Installing php-xml seems to have fixed it.
thanks again.
