Question on how to use Xpath in response of a request

[Mathijs Groen]

I perform a http request which results in a response containing a large xml 
file.

Now, I want to find a specific value for a specific tag. Example “parameter1” 
should have value “123”

Can I use Jmeter XPath Assertion for that? And how to implement this?

(I am pretty new to Jmeter).

Thanks,
Mathijs
