I am trying to come up with a more efficeint way to parse a large (2 GB) xml readonly file that is gzipped and does not have a root node. Right now I use IO::Pipe like this 
$fh = new IO::Pipe;
$fh->reader("echo '<root>'; gunzip -c somefile.xml.gz; echo '</root>';
+");

[download]
then I pass the $fh to XML::Parser::Expat. What I would like to do is use IO::Zlib and pass that into XML::Parser::Expat. However, I am not sure how I would handle injecting a root element into the IO::Zlib stream. Has anyone ever done something like this before?

Best Regards

Ty
