You can imbed <script> in your XSLT, and using "document.writeln()" functions create and HTML objects you want.

This is SAMPLE.XML…

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="sample.xsl"?>
<root>
<thing id="0">
<data>zero</data>
</thing>
<thing id="1">
<data>one</data>
</thing>
<thing id="2">
<data>two</data>
</thing>
<thing id="3">
<data>three</data>
</thing>
</root>

This is SAMPLE.XSL…

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<script>
document.writeln("<h1>This is a test</h1>");
</script>
<body>
<table border="1">
<tr bgcolor="#c0c0c0">
<th>Id</th>
<th>Data</th>
</tr>
<xsl:for-each select="root/thing">
<xsl:if test="@id>’0′">
<tr>
<td><xsl:value-of select="@id"/></td>
<td><xsl:value-of select="data"/></td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

However, newer versions and other XML APIs don't. You can do just about anything within XSLT that you'd be able to accomplish through JavaScript, but it's a different way of thinking about it. I would recommend looking into XSLT named templates (http://www.devx.com/getHelpOn/10MinuteSolution/20363), which are somewhat analogous to javascript functions. Keep in mind that scope and context - where you are in the processing of a given node and what data is available to you - is very important. It's particularly hard to set and manipulate global variables as you transform XML with XSLT. Good luck.
