XPath parser in Java

[kgw]

Hi,Is there any XPath parser written in java?What I want is: given an XPath string, let say /a/b[pred01]/axes::*/... (pred01 can be anything)it would return the steps of the XPath, ex: a, b[pred01], axes, ...or something more detailThanks,kgw

Xercec2-j is an XML parser for JAVA. There's also JAXP from Sun themselves. This few pages article discusses different JAVA parsers. It's probably good to read as it discusses good pointers such as the Performance of each one.

Hi boen_robot,Thanks for the article, but actually it's not what I am looking for. I am not looking for XML parser (parser to parse XML document), but rather XPath parser (to parse XPath). But I do not want the XPath parser to evaluate the XPath expression and return me XML nodes (I don't want the XPath parser to query the XML document). Rather, I want the XPath parser to return me an array or a list or tree or anything where I can go step by step. I am looking for something like this:xpath = XPathParser.parse("/a/b[P and Q]/following::*");xpath.step(1) will return axis = child, NameTest = axpath.step(2) will return axis = child, NameTest = b, predicate = P and Qpredicate can further be divided into predicate.part(1) = P, predicate.part(2) = Q, predicate.boolean() = andxpath.step(3) will return axis = following, NameTest = *Thanks,kgw

I don't think there is such a thing. Simply because it's not something that needed. You could construct something like this yourself by using regular expressions, but I feel it's not worth the effort.

Hi,I post the question to other mailing list and they give me the following xpath/xquery parser. They are W3C recommendation.http://www.w3.org/2005/qt-applets/xpathApplet.htmlhttp://www.w3.org/2005/qt-applets/xqueryApplet.htmlRegards,kgw
