Thanks for reply.
I agree XML::Compile does not belong in this comparison.
This comparison should not be considered as comparisons of performance of different parsers.
I was just trying to compare these for my case and really think XML::Compile a great code. It supports all schema validations etc and fits well for my case too.
I was looking for a possible plug in to XML::Simple with better performance.
I had checked XML::LibXML::Simple too but not of much difference as both take much time in converting to perl hash than actual parsing.
Here is result for two
s/iter xmllibxmlsimple xmlsimple
xmllibxmlsimple 22.8 -- -3%
xmlsimple 22.2 3% --
