Dynamic parameter names in xsl

[systemutvecklare]

Hi!

I have an application that generates an html-form from an xml-file
using an xsl-file. My problem is that I want the xsl to use some
"unknown" parameters that I pass to the xslt processor before
processing the xml. The parameters are not totally unknown but they are
not static, they are built by an attribute in the xml and a constant
name.

Is it possible to define a "runtime" parameter and use the value passed
to the xslt processor?

xsl example:
.... begin code ...
<!-- BUILD PARAMETER NAME -->
<xsl:variable name="param_name"><xsl:value-of
select="@name"/>_T</xsl:variable>
<!-- DEFINE PARAMETER -->
<xslaram name="$param_name"/>
<!-- USE PARAMETER -->
<xsl:if test="$param_name = 'some_value'">do something</xsl:if>
.... end code ...

Any other solution to this problem is appreciated

Thanx!
/Andreas

No, you'll have to redesign your xslt.

Use a single xslaram, whose value is a node-set that combines many
name-value pairs. Then you can use this "aggregate parameter" (or
"environment") like this:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:myParam="my:myParam"
exclude-result-prefixes="xsl myParam">

<xslutput omit-xml-declaration="yes"/>

<myParamaram>
<param name="param1">
<value>xxx1</value>
</param>
<param name="param2">
<value>xxx2</value>
</param>
<param name="param3">
<value>xxx3</value>
</param>
</myParamaram>

<xslaram name="pallParams"
select="document('')/*/myParam:*[1]/*"/>

<xsl:template match="/">
<xsl:value-of select=
"$pallParams[@name='param2']/value"/>
</xsl:template>
</xsl:stylesheet>
