title: VB.NET XML Parser - Find elements with specific attribute & value
body: <p>HI,</p>
  
  <p>I am using VB.NET to read an XHTML file. I need my program to find every element within the XML structure which has the "class" attribute set to a specific value.</p>
  
  <p>IE: I need an array (or similar list) of all elements from the document which contain class="mytag".</p>
  
  <p>There is a list of several values I need to detect, all of which start with the same word 'mytag' followed by another word - so using a "contains" function seems sensible here.</p>
  
  <p>Any suggestions of ways I can parse out these attributes would be appreciated.
  Cheers.</p>
