PHP/RSS Question

[nasium]

I've been exploring RSS 2.0 and while testing some initial code I keep getting stuck on the same error.

"An invalid character was found in text content. Error processing resource"

http://www.zeropaid.com/includes/xml_topguides.xml

I've tried the following to remove the invalid character with no luck:

$desc = strip_tags($desc, '<a><b><i><u>');
$desc = eregi_replace("(<)+(.*)(>)+", "", $desc);
$desc = ereg_replace ("'", "", $desc);

$desc = htmlspecialchars($desc, ENT_NOQUOTES);

I have also tried using CDATA to encode the description field, but I still get the error.

Is there any way in PHP or RSS to encode the data going into the description field? How can I effectivly get around this without creating all this code and not get the error?

Thanks,
Jorge G.

Try str_replace("'","",$str). This will replace every apostrophe(') with a grave().
