Thanks Michael Kay! Your suggestion worked. And the
"<?xml versionfiltered="1.0".... part must have crept
in while I was copy pasting it thru openoffice writer!
For anybody that might be interested, here is the XSLT
that works for my example.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="http://www.w3.org/2005/02/xpath-functions"
xmlns:xdt="http://www.w3.org/2005/02/xpath-datatypes"
xmlns:xlink="http://www.w3.org/1999/xlink">
<xsl:template match="a">
<html>
<head>
<title>Sample</title>
</head>
<body>
<h1>
<center>
Sample
</center>
</h1>
<p/>
<table border="2" bgcolor="yellow">
<tr>
<th>P</th>
<th>Q</th>
<th>text</th>
</tr>
<xsl:apply-templates/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="a" mode="child">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="b">
<!--xsl:for-each select="//b"-->
<xsl:choose>
<xsl:when test="@url">
<xsl:apply-templates select="document(@url)"
mode="child"/>
</xsl:when>
<xsl:otherwise>
<tr>
<td>
<xsl:value-of select="@p"/>
</td>
<td>
<xsl:value-of select="@q"/>
</td>
<td>
<xsl:value-of select="."/>
</td>
</tr>
</xsl:otherwise>
</xsl:choose>
<!--/xsl:for-each-->
</xsl:template>
</xsl:stylesheet>

Message-ID: <005101c69439$58ad58c0$6401a8c0@turtle>
Your stylesheet needs to include within it an
instruction such as
<xsl:apply-templates select="document(@url)"/>
to dereference the links and recursively process the
referenced
document.
I don't know what this is supposed to be:
<?xml versionfiltered="1.0" encoding="UTF-8"?>
but it isn't XML.
