Here it is. But the whole thing is about how the XML/XSLT works 
so I put [OT] in title.

Suppose user inputs firstname "Hello" and 
the program gets the lastname "World".

In TT: one has the two scalar variables passing to
<html>
<body>
[% firstname %] [% lastname %]
</body>
</html>

And in H:T, it is
<html>
<body>
<TMPL_VAR firstname> <TMPL_VAR lastname>
</body>
</html>

And in XHTML it is a style sheet:

<?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="/topspace">
<html>
<body>
<xsl:value-of select="firstname"/>,
<xsl:value-of select="lastname"/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

The idea is either to send to client a XML data file with 
the reference to the style sheet:
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="that_file_on_disk.xsl"?>
<topspace>
    <firstname>Hello</firstname>
    <lastname>World</lastname>
</topspace>
(this does not work with some 5.0 IE browsers)

Or use a libary to translate the dynamical field 
<xsl:value-of select="firstname"/> into the real string 
(which is "Hello") and then send, in the similar
way to TT, H:T.
