Hi,
I'm trying to run a simple XPath extraction (something like //li/a...@href]
through a html document by the help of the 'XPath Extractor' Post Processor.
It does not work, and all i get from the jmeter.log is
2009/09/04 13:25:18 ERROR - jmeter.threads.JMeterThread: Test failed!
org.apache.jorphan.util.JMeterError: error on (//li/a...@href])

How I interpret the line 'Caused by: java.io.IOException: Server returned
HTTP response code: 503 for URL: http://www.w3.org/TR/html4/strict.dtd' is
that Jmeter tries to validate my XPath expression based on this dtd, but
Jmeter (or the user agent it pretents to be) is not allowed to fetch that
document.
I already tried to set the user agent (by using the HTTP Header Manager) to
my current FF installation which definately IS able to download that dtd,
but no success.
I'd be interested in turning off that validation completely, OR pointing to
a local copy of it...and again, haven't found any info whatsoever
I'm a bit clueless about any further options or whether i'm dealing with a
Jmeter bug...
I'm truly looking forward to your answers :)
Cheers
