hello,
thanks for the advice. You're right - I should have given more data. The
reason I'm trying to kill elements from the XML is because the size of the XML
I'm dealing with can get hideous - up to 100Mb. I read Uri's article on
slurping and that helps alot ( http://www.perl.com/pub/a/2003/11/21/slurp.html
) ie avoiding line by line processing gained big speedup. Basically there are a
lot of legacy scripts using XML::Simple that I'd like to leverage (which were
obviously done on smaller xml's!)...hence looking to pre-slurp and pre-kill
unneeded entities from the input XML.
I'm open to using a module but pure reg exp (non line-by-line) seems
faster...and speed is important in this case due to filesize.
Grateful for any ideas u may have.
Cheers, Alan

A couple of thoughts: If you read this list regularly, you already
know the advice you're going to get: there are hundreds of xml modules
on CPAN. Use them! Don't reinvent the wheel.
If you really insist on doing this by hand, we need to see more code.
How are you approaching this? On the surface, it looks pretty simple:
{
$lf = "\n";
local $/ = "" . $lf;
whlie (<>) {
print unless /DW_TAG_TI_reserved/;
}
}
Your question, though, leads me to think there's more going on.
So let me just reiterate my original advice again: use a mudule.
HTH,
