Identifying an element

I have an XML file that contains elements that may have repeating values.

I want to identify the first instance of this value. Does anyone have any
ideas on how to do this?

Below id my example and I want to grab the first instance of <ME/> that
equals "282214"
<?xml version="1.0" encoding="UTF-8"?>
<test>
  <test>
    <PS/>
    <ME>282214</ME>
    <SEL>yes</SEL>
    <QUES>A</QUES>
  </test>
  <test>
    <PS>PRICING</PS>
    <ME>282214</ME>
    <SEL>NO</SEL>
    <QUES>BB</QUES>
  </test>
  <test>
    <PS/>
    <ME>xcxcvxv</ME>
    <SEL>NO</SEL>
    <QUES>What are you doing</QUES>
  </test>
</test>
