Hi, 

Does the XPath Extractor have the ability to set up multiple variables just 
like the regex retractor (XXX_1, XXX_2, XXX_matchNo)? 

I've played around with it some more, I removed saxon jar files I had in the 
Sun6 jre/lib/ext folder and from JMeter's lib folder. 

Now the java spike runs fime from Jedit console and from the system command 
line. I also tweaked the java program to make it into beanshell and it runs ok 
in standalone beanshell from the system command line 

Now when I run it from JMeter (saxon jars removed from lib folder), the 
following error is showing up in the log file: 

2009/07/24 12:21:16 INFO - jmeter.util.BeanShellTestElement: Starting 
/home/nobrien/projects/newbay/main/sng/sng-acceptance-tests/test/jmeter/data/scripts/ExtractOrderedEntries.bsh

Looks like it can't find a XPathFactoryImpl class in the classpath. From the 
standalone beanshell and java app now run from the system command line, the 
following classes are used to successfully execute the XPaths: 

>>>>>>>>>>>>>>>>>>>> 

nobr...@olympia:~/sandbox/Java/XPath$ beanshell XPathDemo.bsh

updatedNodes: 22 
displayNameNodes: 22 
statusNodes: 22 
snsNodes: 22 

>>>>>>>>>>>>>>>>>>>> 

Looks like when JMeter runs it somehow is not able to find 
com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl ?? 

FWIW, here's the JARS that are in JMETER/lib:
