theres nothing preventing you from using it today. Below are 2
(untested) snippets for Jaxen and JXPath (I prefer Jaxen). Note that the
xpath expression has to be applied to the w3c DOM kept inside the page,
and has to be mapped back to the HtmlElement after retreival.
There has recently been some discussion about the need of the latter
operation ;-).
//Jaxen Code:
/////
HtmlPage page = ...;
XPath xpath = new DOMXPath("/HTML");
Element w3cHtml = (Element)xpath.selectNodes(page.getElement()).get(0);
HtmlElement html = page.getHtmlElement(w3cElement);
//JXPath
/////
HtmlPage page = ...;
CompiledExpression expr = JXPathContext.compile("/HTML");
JXPathContext context = JXPathContext.newContext(page.getDocument());
Iterator it = expr.iteratePointers(context);
Element w3cHtml = (Element)it.next();
HtmlElement html = page.getHtmlElement(w3cElement);
