$contents = preg_replace( "|<item>.*?$file.*?</item>|si", "", $contents );
it's being run on an XML file, where each entry is <item>......</item> with a $file pointer in there.
it works okay, except for the fact that it deletes that record, and every record before it. i can't figure out why it's being greedy? i know i gotta be missing something real simple...
What are the possible values of $file? Are you looking to replace just a specific occurance of a $file between <item> tags? Maybe this will help:
$contents = preg_replace("|<item>[^<]*$file[^<]*</item>|si","",$contents);
or just use the 'U' modifier for "ungreedy"...
