Subject Re: [jira] [Updated] (SYNAPSE-955) XPath1.0 Implementation On Top Of XMLStream
Date Thu, 19 Sep 2013 17:45:37 GMT
Hi Isuru,

See my comments below.

- We may have room to improve the API of the xmlstreaming xpath and current
api need to be cleaned up a bit.
- We need to add namespace support in xmlstream based xpath impl as it is
commonly used in most integration scenarios.
- xmlstreamingxpath is currently under synapse core utils and its pretty
much independent from synapse. We might move it some other module than
synapse-core.
- Also during testing, I found some limitations with text nodes(text()). We
can work on improving those aspects as well.
- And I think we are good to go ahead with performance comparison for CBR
with xmlstream xpath and existing xpath support.

Thanks.
