[thelist] PHP - insert text at specific place in file?

OK, here's what I'm aiming for. I have an input form which is meant to
simultaneously write both an HTML 'news' file and an equivalent RSS
file, using variables passed from the form.
I have the HTML part mostly figured out -- I can append new news items
at the top of the file, where I want them.
But for the RSS file, new items would of course have to be inserted at a
particular point in the file, specifically, immediately after the
closing </channel> element. Here's a snippet showing what I mean:
print "<channel>";
[snip]
print "</channel>";
[want to insert new item here, e.g.:]
$item .= "<item rdf:about=\"http://foo/" . $newURL . "\">";
$item .= "<title>" . $newtitle . "</title>";
[snip]
$item .= "</item>\n";
[snip]
$fh = fopen('file.xml'...);
So what I need to do is open 'file.xml', find the </channel> element,
and then insert a new <item> above any pre-existing <items>. Is there a
way of doing something like this in PHP, perhaps using preg_match or
something along those lines?
