Hi Erik,

 

You mentioned that I could marshall a Castor generated object into DOM.

How do you do that - could you provide a few lines of code or pointers - greatly appreciated.

XPath only works on java if you use a tool -- like JXPath at http://jakarta.apache.org/commons/jxpath/.

I haven't seen people on this maillist talk about this.

 

You can always marshal a Castor generated object to DOM and then use XPath on node.

would you elaborate a bit?

Subject: [castor-dev] XPath usage

Is there a way to elegently get to the targets defined by an XPath in the schema? Does Castor directly support

XPath linkages like DOM? Also if some one could point to code sinppets that illustrate XPath target extraction out

of Castor generated Java classes that would be really cool. I searched all of Castor web site and in google but could

not find any for XPath usage in castor.

 

Currently out of the generated classes, I do a small method call which incloves a string-walkthrough to get to the

actual target, and then do subsequent processing.

 

Thanks,

Girish.
