[Webtest] [webtest][JIRA] Closed: (WT-412) XPath: Migrate from Jaxen to DOM based XPath (Warning: may cause some XPath failures)

Marc Guillemot closed WT-412:
-----------------------------

    Fix Version: Future versions
     Resolution: Fixed

Done in build 1700.

*Warning: possible fixes needed in XPath usage*

HtmlUnit doesn't use Jaxen with a custom document navigator anymore for XPath processing but Xalan with standard DOM node navigation. This has different consequences:

- shortcuts to verify text content of a node don't work anymore
ex: //tr[td = '2.1'] should be replaced for instance with //tr[td/text() = '2.1']

- spaces are not trimmed in text
ex: if the text of the above td is "  2.1", the XPath expression should be changed to //tr[td/text() = '  2.1']. Alternatively you can use the wt:cleanText function //tr[wt:cleanText(td) = '2.1']

- syntax check is less forgiving: I've seen some cases of invalid xpath expressions (for instance with a ")" instead of a "]") that were accepted previously but that are not accepted anymore.
