title: Getting a set of elements using linq
body: <p>I have the following piece of XML:</p>
  
  <pre><code>&lt;xml&gt;
     &lt;ObsCont xCampo="field1"&gt;
        &lt;xTexto&gt;example1&lt;/xTexto&gt;
     &lt;/ObsCont&gt;
     &lt;ObsCont xCampo="field2"&gt;
        &lt;xTexto&gt;example2&lt;/xTexto&gt;
     &lt;/ObsCont&gt;
     &lt;ObsCont xCampo="field3"&gt;
        &lt;xTexto&gt;example3&lt;/xTexto&gt;
     &lt;/ObsCont&gt;
  &lt;/xml&gt;
  </code></pre>
  
  <p>How do I (using linq) get for example what is inside the xTexto tag that has as parent the ObsCont with the xCampo attribute "field2" ?</p>
  
  <p>(c#, vb.net, your choice)</p>
