Hello,
I am about to use VTD-XML (found at http://vtd-xml.sourceforge.net/) but I am interested in getting real-case usage feedback, by any one that has used the library and has any comments.
At the URL (http://vtd-xml.sourceforge.net/) there are benchmarks but if someone has used VTD-XML and has comments FOR it I would like to hear them. Speed is a critical factor in the application and comments after real-case usage, by developers, is what i am looking for.
Regards,
VTD-XML performance has been measured by a number of sources, below are some of them
This report (https://code.ai.techfak.uni-bielefeld.de/trac/xcf/wiki/Evaluation) has numbers that measures the parsing/xpath performance comparing to XOM, binary XML, SAX and DOM
Also xmlbench (search it on the web as a keyword) will lead you the open source project dedicated to XML parsing performance site
VTD-XML web site also has a number of benchmark reports (there will be updates soon).
I use VTD-XML for faster XPaths. Previously, my application was using DOM to apply XPaths on a document which took about 20 minutes on a 17MB document. I thought about switching to SAX, but SAX does not support XPaths, is quite "user-unfriendly" and would have required a lot of code restructuring. So I migrated quite painlessly to VTD-XML and my xml processing now takes about 20 seconds!
