title: Build XPath using wildcard for changing strings
body: <p>I am trying to build an XPath for a property that is constantly changing. The number prefix is bound to change sometimes. </p>
  
  <p>Original: </p>
  
  <pre><code>//*[@id="MainContent_DXEditor3_I"]
  </code></pre>
  
  <p>which I can query using</p>
  
  <pre><code>$x('//*[@id="MainContent_DXEditor3_I"]
  </code></pre>
  
  <p>Intended use: I would like to build the string to handle any number in the sub-string. Example: if the property changes to 'MainContent_DXEditor33_I' or 'MainContent_DXEditor8_IXYZ' - I still want to be able to find the element without having to rebuild</p>
