SimpleXML and ADO XML

[=?iso-8859-1?Q?=C1lvaro?= G. Vicario]

I've spent an hour trying to make SimpleXML work until I realized the
problem seems to be namespaces. This code:

<?php
$xml = simplexml_load_ file('foo.xml') ;
print_r($xml);
?>

works fine, unless the XML file contains tags with colons, e.g.:

<rs:data>

In this case, I get an empty object. What am I missing?


I need to parse third-party XML files. I believe it's ADO XML:

For the records: I finally discarded SimpleXML. It's only simple when
you don't have namespaces.

I tried the XMLReader extension with sample code taken from a user
note in the PHP manual and I got it working in a few minutes, although
the code is not intuitive at all. I also tried the DOM extension and
the results were similar, but the code was slightly more intuitive.

Finally, I found a PHP port of JavaScript's jQuery library: phpQuery
[1]. I parsed my XML with a few lines of code and I can even
understand them :) Using such library is probably an overkill but it
was quick and easy.
