XSLT: Global Parameters - .NET Framework

Stefan Schmitz

I have a problem using a global parameter to control the
XSL-Transformation of my XML-Document.

My XML-Document looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<Football xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespace SchemaLocation= "d:\_Privat\Foo tball\XML\Footb all.xsd">
<Season>
<Opponents>
<Opponent ID="ID1001" Town="Duesseldo rf"/>
</Opponents>
</Season>
<Football>

And my XSLT:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:styleshe et version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">

<xsl:output method="html" encoding="UTF-8" indent="no"/>

<xsl:param name="Selection " select="Try"/>

<xsl:template match="Football ">
<html>
<xsl:apply-templates/>
</html>
</xsl:template>

<xsl:template match="Season">
<head>
<title>
<xsl:text>Saiso n </xsl:text>
<xsl:value-of select="@Year"/>
<xsl:text> (</xsl:text>
<xsl:value-of select="$Select ion"/>
<xsl:text>)</xsl:text>
</title>
</head>
<body>
<center>
<xsl:text><xsl: value-of select="$Select ion"/></xsl:text>
</center>
</body>
</xsl:template>

If I transform the XML-Document with this stylesheet the
value-of($Selection)-Part is in both cases empty. If I change the
select-Value to 1 or 12 (Number) or add this to the
Xalan-Transformator (-p Selection 1) as a parameter the given value
appears. But I can't understand why this only works with numbers? What
am I doing wrong?

Thanks
Stefan

The problem is here:

<xsl:param name="Selection " select="Try"/>
This will select the node-set of all children with name "Try" of the current
node (the document node "/") -- that is either the top element of the xml
document is named "Try" in which case it will be selected, or the XPath
expression "Try" will select nothing -- and this is exactly your
case as the top element is named "Football".

The solution is to use:

<xsl:param name="Selection " select="'Try'"/>

that is, enclose Try in inner apostrophes. Then it is interpreted as a
string literal and not as a name that is part of a location step of an XPath
expression.
Hope this helped.
Cheers,

Possible to include other tags in a XSLT file?

Is it possible to include addition tags in a XSLT file, that the XSLT processor will, for all practical purposes, ignore? What I'm looking to do is to include a section to contain information regarding what parameters the XSLT file is expecting. Then my program can retrieve the information from the style sheet and prompt the user for the necessary parameters. I'm envisioning the section would be something like this: <myParameters>

The main idea is that template B is independent of template A, i.e.
