title: XPath string for selecting data types
body: <p>I have an XML Document that specifies certain data instead data nodes like so:</p>
  
  <pre><code>&lt;data type= "arbitrary value"&gt;Value&lt;/data&gt;
  </code></pre>
  
  <p>I need to be able to look through this document and select the above node.</p>
  
  <pre><code>XmlNode node = xmlDoc.SelectSingleNode(data[contains(.,'arbitrary value')]);
  </code></pre>
  
  <p>The above statement does not work.</p>
  
  <p>How can I find nodes with a certain "type"?</p>
