XPath1.0 implementation on top of XML Stream
Hi
This project will be used in Synapse content based routing in order to
increase the performance of the XPath evaluation. Up to now it is supported
for following kind of XPath queries.
/step/step
/step/step[number]
/step/step[name relation
value](relation : = or !=)
so as next steps i have planned to do the following
Do more test on above implementations.
Improve and Optimize code
Do performance test with current
AxiomXpath
Developed API for integrate with
Synapse.
For develop the API I have to know the following facts.
When OMElement is received for XPath evaluation it may or may not
matches with the query.if it is matched what will be the output.Is it
OMElement build from the result or exact OMElement received for evaluation
or may I need to develop methods for get both when needs?
thanks

hi andreas,
I have move the source code to [1] and customized the algorithm in paper
according to specific requirements in axis evaluation.I will attach the
patch to Synapse jira as well.

Where's the source code? I don't see any commits in your SVN repo [1]
since May 21.
Also, what is the algorithm that you finally selected?

Hi all,
Following Axis supports are added
child ,attribute, descendant,
Descendant-or-self,following,following-sibling,self
So this takes XMLStreamReader as input and gives resulting outputs as
OMElements. This will reduce the overhead of building complete OMElement
from XMLStream and it only builds the result.
As next steps I have planned to improve test cases and integrate this in to
Synapse.
thanks

I think your API should just return the OMElement resulting from the XPath evaluation. Check the SynapseXPath class.
