Question

I would like to know if there is a way to view all the Global Parameters in XSLT without explicitly knowing the name.

ie

<xsl:param name="T"/>

In my cms I have a text box whereby I may enter “T=whatever,A=dave” These parameters are then added programmaticly for access within the XSLT document. Now supposing i do not have source access, is there any way to expose the parameters name and value without knowing the name to begin with?

Kind Regards,

You must already have an xsl:param defined with the same name in your XSLT transformation — otherwise a value cannot be passed to non-existent parameter.

And there is no-way to find the (dynamic) values of global parameters if you don’t know the parameter names statically.

It is possible to have something like this:

<xsl:variable name="vGlobalParamValues" select=
 "document('')/*/xsl:param/@select
|
  document('')/*/xsl:param[not(@select)]/node()
 "/>

But this selects only the compile-time values of the parameters and could return something like:

<xsl:apply-templates/>

which, of course is not the result of actually applying the templates.

A correct way to pass unknown name-value pairs as parameters is to make them part of a single global parameter, such as:

<xsl:param name="pParams">
 <param name="someName1">someValue1</param>
 <param name="someName2">someValue2</param>

  .  .  .  .  .  .  .  .

 <param name="someNameN">someValueN</param>
</xsl:param>
