title: select xml child element with jQuery
body: <p>Is it possible to find an xml element by searching with the value of a child element?</p>
  
  <p>So for  XML such as:</p>
  
  <pre><code>&lt;route&gt;
      &lt;name&gt;Lakeway&lt;/name&gt;
      &lt;abrv&gt;LAKE&lt;/abrv&gt;
      &lt;eta&gt;
          &lt;time&gt;00:30&lt;/time&gt;
          &lt;dest&gt;MAIN&lt;/dest&gt;
      &lt;/eta&gt;
  &lt;/route&gt;
  </code></pre>
  
  <p>If I only have the value of the <strong>abrv</strong>, how would I parse the xml so as to get at the <strong>eta</strong> tags' child elements? </p>
  
  <p>Is this doable with jQuery without looping through each element and comparing the values to the defined variable? Or is there a better way to do this?</p>
  
  <p>EDIT:</p>
  
  <p>I am trying to parse an XML feed from another domain. I'm not sure if I can do that with the xmlParse function, or if I'll need to use jQuery's Ajax functions?</p>
