can write xpath expression extract success property value 'true' response.

i've been using following online tool - http://www.freeformatter.com/xpath-tester.html test attempts, each attempt returned !no match.

here xpath expression though correct:

//getcityforecastbyzipresponse//getcityforecastbyzipresult//success

hope can help.

p.s webservice used generate response can found here: http://wsf.cdyne.com/weatherws/weather.asmx - i'm using getcityforecastbyzip service. cheers!

this due namespaces either have 'register' them upfront in used xpath engine or use xpath based solely on element name below

//*[local-name()='getcityforecastbyzipresponse']/*[local-name()='getcityforecastbyzipresult']/*[local-name()='success']
