title: Parsing XML string using XSLT
body: <p>I have an XML document that has a TextBlock that contains HTML code.</p>
  
  <pre><code>&lt;TextBlock&gt;
    &lt;h1&gt;This is a header.&lt;/h1&gt;
    &lt;p&gt;This is a paragraph.&lt;/p&gt;
  &lt;/TextBlock&gt;
  </code></pre>
  
  <p>In the actual XML, however, it is coded like this:</p>
  
  <pre><code>&lt;TextBlock&gt;
    &amp;lt;h1&amp;gt;This is a header.&amp;lt;/h1&amp;gt;
    &amp;lt;p&amp;gt;This is a paragraph.&amp;lt;/p&amp;gt;
  &lt;/TextBlock&gt;
  </code></pre>
  
  <p>So when I use <code>&lt;xsl:value-of select="TextBlock"/&gt;</code> it displays all of the coding on the page. Is there a way using XSLT to convert <code>&amp;lt;</code> to <code>&lt;</code> within the TextBlock element?</p>
