How can i get value of attribute base on matched value?

i want get value of attribute base on matched value. Here my XML file

<Setup>
  <Include Type="Product">
    <Value uomid="8078">468922</Value>
    <Value uomid="8078">468908</Value>
  </Include>
</Setup>

So, i would like to take uomid base in matched value. And the process in codebehind Ex: I set my parameter value is: 468922 so my result i wanna get is 8078 of 468922 not 8087 of 468908. Thanks
