I looked into the Xalan implementation and the problem appears to be in
creation of the DTM used by the underl

Implementation seems to work but does not provide as much benefit as expected.
Jasper tag pooling does not pool tags with the same attribute values so the
select attribute is set every time causing recompilation. The time taken to
iterate 1000 tags drops from around 2800ms to 1800ms.

expressions and an implementation of an XPathVariableResolver that handles the
JSTL variable resolution scheme.
There are ver

In light of the performance issues logged against the XML taglib and functional
issues like #49578, I was looking at refactor the XML tags to use the JAXP
XPath API to pre-compile expressions and dynamically resolve variables. I think
this can be done fairly easily and will eliminate a lot of th
