[Jaxen] how can i get a dom node form a xpath?

[kevin dong]

hi, all.   I found a problem when i used following code:   /////////////////////////////////////////////////// org.jaxen.dom.DOMXPath thePath= new DOMXPath(theCursor); org.w3c.dom.Node thePointNode=(org.w3c.dom.Node)thePath.selectSingleNode(theContentDocument.getDocumentElement()); thePointNode.setNodeValue(domainValue); ////////////////////////////////////////////////////////////   I got a cast exception, so my question is: how can i modify a node value use xpath? or I must do the task by myself?       thanks in advance?     kevin dong
