How to extract a value attribute from an input tag where the body is a web page?

I’m running a GET call to return a web page as body
I want to extract the value attribute of a named ‘input’ tag from the XML body.
Any suggestions on how to do this?
TIA

Hey @davout_uk. Can you help me understand the use case better?
From what I know so far, you are trying to parse an XML response from a GET request to get a particular value. Here’s how you can do that.

The pm.reponse API does not have a .xml() method to parse XML responses directly, you can read more about the API here. To do so, you’ll need to use one of the built-in library modules, called xml2js. Your test script would look something like.

var parseString = require('xml2js').parseString;

parseString(pm.response.text(), function (err, result) {
    pm.globals.set("xml_parsed_response", JSON.stringify(result));
});

Now that you have the parsed XML response stored as a global variable, you can access it in the subsequent request using pm.globals.get("xml_parsed_response"); and access the required key using the dot notation.

Remember that parseString is an asynchronous function and you’ll have to set the result to a global/environment variable to access it in subsequent requests.

Feel free to reach out in case this wasn’t your exact query or if you need additional help.

It sounds like you are interested in parsing HTML and not XML.

It that is the case, I would suggest looking into the cheerio library.

I have done a tutorial on how to use cheerio in this video: https://youtu.be/B4ilccLUQVs

Otherwise please clarify the questions, as @deepak.pathania suggested.
