Subject Re: Performance issues with Santuario 2.1.1 performTransforms
Date Mon, 16 Apr 2018 15:15:37 GMT
I took a quick look at the test-case - I think the problem is that using an
XPath Transform is just not efficient with a very large input document, as
the XPath Filter gets called on each input node. I'm not sure if there's a
more efficient way of implementing the code - the XPath Transform is not
used very often from my experience.
