title: Value-of in <a> html markup
body: <p>I have this XSL file :</p>
  
  <pre><code>&lt;xsl:template match="attribute"&gt;
   &lt;a  href="-"&gt;
      mylink
   &lt;/a&gt;
   &lt;xsl:value-of select="url" /&gt;
  </code></pre>
  
  <p>I want to put the value of my the url attribute in the href.</p>
  
  <p>Do you know how to do this ?
  Because <code>&lt;a  href="&lt;xsl:value-of select="url" /&gt;"&gt;</code> doesn't work.</p>
