How to read XML output from an integration output..?

I am not sure I understand your actual question.

You can cast a XML structure to CDT and use xpathsnippet to navigate in the XML structure.

docs.appian.com/.../fnc_scripting_torecord.html

docs.appian.com/.../fnc_scripting_xpathsnippet.html

Actually, we are not using any CDT's and totally working with Records. And I will be getting an integration output in an XML format, and I have to consider some tags from that output to calculate the score which is my requirement.

Yes that's what Stefan suggested, you can use xpathsnippet() or extract() function to get the required tags from the XML output.

Well, then the xpathsnippet allow you to fetch specific values from the XML and use them.

Thank You Stefan.

Yeah, Thanks Sanchit.
