           Summary: [PATCH] New XPathResponse function to extract data from
                    Response
           Product: JMeter
           Version: Nightly (Please specify date)
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Main
        AssignedTo: jmeter-dev@jakarta.apache.org
        ReportedBy: hpaluch@gitus.cz


Hi folks!
  I created a new JMeter function, that allow to extract value from HTML 
response using XPath query. This way it should be much more reliable to obtain 
values of select/option etc than making complex regex.
  This function is complement to existing XPath function - that is capable to 
query files only.

Typical usage:
${__XPathResponse(/html/head/title,myTitle)}
     - extracts Title from HTML response and put it to myTitle variable 
${__XPathResponse(//form[@name='countryForm']//select[@name='country']/option
[text()='Czech Republic'])/@value}
     - extracts value attribute of option element that match text 'Czech 
Republic'. It is very handy feature when we know text of option element but 
need to get its value (usually some numerical id from database).

Bugs/notes:
 * no DOM caching - DOM tree is created on every function invocation 
 * need to do better exception handling

It would be nice to have handy response.getDataAsDomHtml() or similar to create 
DOM on demand for every possible caller (XPathAssertion, XPathResponse etc..), 
but currently I have no idea, what would be acceptable solution.

Any idea?
