How to extract the values from request input xml in jmeter

I wanted to extract the value of refid1 and refid2 tags form the input xml in Http request. refID1 and refid2 values are generated at runtime using random number function . please find below attached screenshot for the problem :

Request tab snapshot from Jmeter.

Thanks in advance!

回答1:

Since you're generating the data, I suppose you have access to the XML request data.

So in this case, you can make those 2 fields variables extracted from CSV using CSV Data Set config.

If you're generating them using JMeter __Random function, then you can use this syntax:

${__Random(0,10, MYVAR)}

And then use ${MYVAR}

回答2:

1. Add JSR223 PostProcessor as a child of your request

2. Put the following code into "Script" area:

   vars.put('request', sampler.getArguments().getArgument(0).getValue())
   

3. Add XPath Extractor after the JSR223 PostProcessor

4. Configure it as follows:

   • Apply to: JMeter Variable -> request
   • Reference Name: anything meaningful, i.e. refId

   • XPath Query: //*[starts-with(local-name(), 'refId')]

5. You will be able to access your "refId" values as ${refId_1} and ${refId_2} where required.
