Hi, [sending again in case lost]
Still fairly new to XML and libxml2. So pardon me if this is a trivial question. We are generating a xapth consisting of a lot of OR for selecting child nodes based on the name. ex. /config/group/[name = "n1" or name="n3" or name="n7" ....] In one instance there are about 17500 "name = value" pairs in the predicate. xmlXPathEvalExpression() of the above xpath takes a long time with gprof data: This is with 2.7.7: time seconds seconds calls s/call s/call name 20.02 1.93 1.93 14007 0.00 0.00 xmlXPathCompOpEval 10.27 2.92 0.99 22980128 0.00 0.00 xmlXPathNodeCollectAndTest 5.39 3.44 0.52 162363242 0.00 0.00 valuePush 4.56 3.88 0.44 113629376 0.00 0.00 xmlStrEqual I also tried with 2.9.0 and did not see much difference. I would appreciate any suggestion on how to improve this xpath query performance. I saw reference to XQuery (indexed) and wondering if that is really what I need. Thanks. -chang _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] https://mail.gnome.org/mailman/listinfo/xml
