title: How to compare against multiple strings in xslt
body: <p>For comparing an xml string value against multiple strings, I am doing the following.</p>
  
  <pre><code>&lt;xsl:if test="/Lines/@name = 'John' or /Lines/@name = 'Steve' or /Lines/@name = 'Marc' " &gt;
  </code></pre>
  
  <p>Can any one tell me, instead of using 'or' in the above case, how can I check whether a string is existing in an set of strings using xslt.</p>
  
  <p>Thanks.</p>
