title: With XSLT/XPath, how can I match any element in the null namespace?
body: <pre><code>&lt;xsl:template match="foo"&gt;
  </code></pre>
  
  <p>matches the foo element in the null namespace.</p>
  
  <pre><code>&lt;xsl:template match="*"&gt;
  </code></pre>
  
  <p>matches any element in <em>any</em> namespace.</p>
  
  <p>I tried:</p>
  
  <pre><code>xmlns:null=""
  ...
  &lt;xsl:template match="null:*"&gt;
  </code></pre>
  
  <p>but it's illegal to declare a prefix for the null namespace.</p>
  
  <p>So how can I match an element with any name in the null namespace?</p>
