How can I check if an XML element exists inside another element in nodejs?

Question

Here is my XML code, what I would like to do is check that within the <testcase> element there is the <failure> element with an if to put conditions.

<testsuites disabled="0" errors="0" failures="1" tests="20" time="102.012">
   <testsuite name="name1" timestamp="2021-01-27T10:20:51" hostname="localhost" time="79.312" errors="0" tests="12" skipped="1" disabled="0" failures="1">
      <testcase classname="nametescase" name="STEP_1: Date filter" time="3.776">
         <failure></failure>
      </testcase>
   </testsuite>
</testsuites>

How can I do this condition in nodejs?

You could use XPath in Nodejs with the following packages: xmldom and xpath

A simple example

var xpath = require('xpath')
var dom = require('xmldom').DOMParser

const xml = `
<testsuites disabled="0" errors="0" failures="1" tests="20" time="102.012">
   <testsuite name="name1" timestamp="2021-01-27T10:20:51" hostname="localhost" time="79.312" errors="0" tests="12" skipped="1" disabled="0" failures="1">
      <testcase classname="nametescase" name="STEP_1: Date filter" time="3.776">
         <failure></failure>
      </testcase>
   </testsuite>
</testsuites>
`

const doc = new dom().parseFromString(xml);
var failureNode = xpath.select("//testcase/failure", doc); //<--- xpath
console.log(failureNode.length);
