title: select-xml does not return any results
body: <p>I'm trying to use the powershell command select-xml to select data from an xml file. When I run the command below no results or errors are returned. I expect a list of the editions to be returned to the screen. What's wrong with this? </p>
  
  <pre><code>PS C:\&gt; select-xml -path "C:\t.xml" -xpath "//edition" | foreach {$_.node.InnerXML}
  PS C:\&gt;
  </code></pre>
  
  <p>The XML file (C:\t.xml) is:</p>
  
  <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt;
    &lt;Book&gt;
      &lt;projects&gt;
        &lt;project name="Book1" date="2009-01-20"&gt;
          &lt;editions&gt;
             &lt;edition language="English"&gt;En.Book1.com&lt;/edition&gt;
             &lt;edition language="German"&gt;Ge.Book1.Com&lt;/edition&gt;
             &lt;edition language="French"&gt;Fr.Book1.com&lt;/edition&gt;
             &lt;edition language="Polish"&gt;Pl.Book1.com&lt;/edition&gt;
          &lt;/editions&gt;
        &lt;/project&gt;
      &lt;/projects&gt;
    &lt;/Book&gt;
