Re: Matching nodes in the default namespace

   Here's the XML:
  <catalog xmlns="http://www.example.com/catalog/">
   <book id="bk101">
     <author>Some author</author>
     <title>Some Title</title>
...

so that is the same input to XSL as

    <c:catalog xmlns:c="http://www.example.com/catalog/">
       <c:book id="bk101">
         <c:author>Some author</c:author>
         <c:title>Some Title</c:title>

   And here's test.xsl:
    <?xml version="1.0"?>
    <xsl:stylesheet version="1.0"
       xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
       xmlns="http://www.w3.org/TR/REC-html40" >
   ....
       <xsl:template match="catalog">
           <xsl:apply-templates/>
       </xsl:template>

and thatmatches an element called catalog in the null namespace (or as
the namespace rec calls it, not in a namespace at all)

You want to match

   <?xml version="1.0"?>
    <xsl:stylesheet version="1.0"
       xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
       xmlns="http://www.w3.org/TR/REC-html40"
       xmlns:c="http://www.example.com/catalog/"
       exclude-result-prefixes="c">
   ....
       <xsl:template match="c:catalog">
           <xsl:apply-templates/>
       </xsl:template>

even if your source file is using "http://www.example.com/catalog/" as
the default namespace.
