[thelist] placing the pointer in a text file using PHP..

[Carl J Meyer]

Tom,

Hrm.  Should have tested that code - not sure what's going on exactly
and don't have time to dig into it.  Looks like the preg_replace isn't
doing its job for some reason, maybe my regex is broke somehow, or maybe
the preg_ functions don't like strings containing newlines.  Anyhow, the
following code is faster and cleaner, and actually does work:

$parsing = false;
while ($data = fread($fp, 4096))
    {
    if($data = strstr($data, '<?xml'))
        $parsing = true;
    if(!$parsing) continue;
    print $data;
    }

Give that a try,

Carl
