Using preg_replace on an XML document is begging for trouble. I think you need to use simplexml_load_file() like I do and parse the XML properly.

hello, i found your page by googling ‘rss filter’…this is similar to what i’m trying to accomplish.

i’m trying to remove certain items from the rss(xml) by keyword so i can use:

http://myip.com/rssfilter?http://somefeed.com

here is my latest attempt on it:
$lnk="http://someatomfeed/atom.xml";
$pg=file_get_contents($lnk);
$pg = preg_replace('#.*?Great.*?#s’, », $pg);
echo $pg;
?>

where it removes an ‘*great* from my $pg xml content
any help would be greatly appreciated

thanks
