[Webtest] bug: evaluating string results in storexpath

[Christopher Painter-Wakefield]

Thanks for implementing storexpath, whoever did it - I've been needing it
badly!

However, it has a bug.  When the xpath expression returns a String instead
of a node, the code throws an exception:
Exception occurred evaluting XPath: The result of the XPath expression is
not a Node. It was: 53752 of type: java.lang.String. You might want to use
a different method such as selectObject() to evaluate this XPath expression

An example of an xpath expression returning a String is:
"substring-after(html/a/@href, '=')", which I am trying to use to just
store just the query parameter out of a url.

It looks like the problem is on the line (in StoreXPath.java):
      Node node = document.selectSingleNode( fXPath );

Since you are returning a String anyway, why not just use "document.valueOf
( fXPath );"?

Can someone apply a fix?

Thanks!
