Hello,
Can someone please suggest me a Perl module for comparing huge XML
Files.
I tried XML::SemanticDiff, but it is taking a lots and lots of time to
load the XML File nodes, elements and attributes to the Hash.
Any suggestions would be really appreciated.
Thank you
-Venkat

Parse and read the XML elements, attributes text into a tree or a hash
and then compare.
I tried using Semanticdiff, but it is taking a lot of time to read the
XML file into Hash.

That will take a lot of time no matter what you do. But define
"huge". And define "a lot of time" :).
If you want efficiency more than anything else then XML::Parser is
still the fastest. Or at least it was the last time I checked.
Implementing handlers to put attributes and CDATA into an HASH is
really straight forward, but if your files are in the 100MB area
that could still take several minutes depending on your hardware.

I have a XML file of sixe 6MB, but it has more than 300,000 elements.

XML::Parser is taking almost 35 minutes to get the result as a tree.
