Looking for a java xpath parser

[ketan (archive)]

Hello,

I am looking for a java-based xpath parser, that will enable me parse a string containing an xpath expression into steps, predicates, conditions etc.

sample expressions: a/b/c, a/b[@name='123'][4]/c[@name='ddd'] etc.

I have looked at a couple and didn't really find what I wanted.. Some did not have methods to get the info I was looking for, one did not support the level of indexing I need...

Any pointers would be greatly appeciated..

Thanks in advance.

Have you tried SAXPath? http://saxpath.sourceforge.net/
Its now part of Jaxen: http://jaxen.org/

JDOM works for me ....

Since that should have been what you looked at first or second - what is there not to like?




XPath xpath = XPath.newInstance("//input[@name='manager_login']"); List ManagerList = null; if ( null != xpath ) { ManagerList = xpath.selectNodes(new Document(myjdom)); }

Thanks for the pointer to JDOM. However, I don't want to actually address into an XML doc, I want to be able to parse the XPATH string and break it apart into it's individual parts and then I need to be able to accss those individual expresions, steps and predicates. A number of parsers to what you are illustrating; however, that's not my application.

Try Googling "Xpath Parser".

I came up with this ...
