title: Conditionally delete Parent Node if Children nodes are empty
body: <p>As the title describes I am trying to take xml like this:</p>
  
  <pre><code>&lt;Measurement&gt;
      &lt;Name&gt;Board_1_Output_0&lt;/Name&gt;
      &lt;LongIdentifier&gt;Board 1 Output 0&lt;LongIdentifier/&gt;
      ...
      &lt;ECUAddress&gt;2000000F&lt;/ECUAddress&gt;
  &lt;/Measurement&gt;
  &lt;Measurement&gt;
      &lt;Name/&gt;
      &lt;LongIdentifier/&gt;
      ...
      &lt;ECUAddress/&gt;
  &lt;/Measurement&gt;
  </code></pre>
  
  <p>and conditionally delete <code>&lt;Measurement&gt;</code> if any child nodes of <code>&lt;Measurement&gt;</code> are empty like this: </p>
  
  <pre><code>&lt;Measurement&gt;
      &lt;Name&gt;Board_1_Output_0&lt;/Name&gt;
      &lt;LongIdentifier&gt;Board 1 Output 0&lt;LongIdentifier/&gt;
      ...
      &lt;ECUAddress&gt;2000000F&lt;/ECUAddress&gt;
  &lt;/Measurement&gt;
  </code></pre>
  
  <p>My current xslt, for this section, looks like this:</p>
  
  <pre><code>&lt;xsl:for-each select="Measurement"&gt;
      &lt;xsl:text&gt;/begin MEASUREMENT&lt;/xsl:text&gt;
      &lt;xsl:text&gt;/* Name           */&amp;#x09;&lt;/xsl:text&gt;
      &lt;xsl:value-of select ="Name"/&gt;
      &lt;xsl:apply-templates select="LongIdentifier"&gt;
      &lt;xsl:text&gt;ECU_ADDRESS&amp;#x09;&amp;#x09;&amp;#x09;&amp;#x09;&lt;/xsl:text&gt;
      &lt;xsl:value-of select ="ECUAddress"/&gt;
  &lt;xsl:text&gt;/end MEASUREMENT&lt;/xsl:text&gt;
  &lt;/xsl:for-each &gt;&lt;!-- Measurement --&gt;
  </code></pre>
  
  <p>I thought I could conditionally look at each section and not print any <code>&lt;Measurment&gt;</code> XML tags if ANY of the children tags are empty, however, I can only achieve leaving the parent <code>&lt;Measurement&gt;</code> element as such: </p>
  
  <pre><code>&lt;Measurement&gt;&lt;/Measurement&gt;
  </code></pre>
  
  <p>Is there a way to delete the parent xml node when I find that I have an empty child in the same xslt stylesheet? Or do I need to run the xml through a different stylesheet to delete any XML nodes that have empty children?</p>
