DOMDocument() problems

latemodern

Hi,

I am following a tutorial from a an Ajax/PHP book. I have written a script the generates an xml document. I keep getting the following error when I try to open the script in a browser (even when I download the code from the support site):

XML Parsing Error: junk after document element
Location: http://hapuk.coreware.co.uk/test/ajax/foundations/php/phptest.php
Line Number 2, Column 1:Warning: domdocument() expects at least 1 parameter, 0 given in /home/chris/happenin/test/ajax/foundations/php/phptest.php on line 5 
^

ie6 says:

The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

Only one top level element is allowed in an XML document. Error processing resource 'http://hapuk.coreware.co.uk/test/ajax/...

Warning: domdocument() expects at least 1 parameter, 0 given in /home/chris/happenin/test/ajax/...

The code that is causing the error is:

// set the output content type as xml
header('Content-Type: text/xml');
// create the new XML document
$dom = new DOMDocument();

I'm assuming that there must be something wrong with the php installation on the server. Anybody got any ideas?

Does the same error happen on your dev server?

As far as I can see, DOMDocument does not require any parameters in its constructor?

What version of PHP are you using on the dev and production servers?

Hi Mark,

Its 4.4.0

Does this mean the DOMDocument function isn't supported? Is there a workaround

Many thanks

Chris

DOM is not provided in PHP 4.x. There is an old domxml_ extension but it provides a subset of the functionality and is not shipped with PHP5 hence only available via PECL.

As 4.x versions are old and new features / extensions are NOT backported, I strongly recommend that you use the stable 5.1 series (at least until 5.2 is released).
