Default Pass Value to XSLT variable


I am trying to learn how to pass a value from either HTML, ASP or Javascript to an XSLT variable. I done a lot of searching, and have no luck.

I would like to pass the value to the following line in xslt:

<xsl:variable name="getvalue">PASSED VALUE HERE</xsl:variable>

Does anyone know how its done? I can use any of the following formats: HTML, ASP or Javascript

Thanks for the help.

Normally you define "variables" that you want to modify externally as xsl:param elements that are direct children of the xsl:stylesheet. It is possible to modify xsl:variable but it's a bit messy. What XSLT processor are you using and what platform and host, e.g. .NET processor, Windows and ASP.NET or Saxon, Windows and JSP?

You want to define a parameter, not a variable: <xsl:param name="x"/> as a child of xsl:stylesheet.

Then when you invoke the transformation (e.g. from Javascript) you'll find the API offers a method such as setParameter() or addParameter() to supply an external value for the parameter.

Thanks guys... I plan on using ASP.NET to process. I will have a web page with an input box and submit button. The inputbox value will be passed to the xslt <xsl:param name="x"/> (thanks Michael) on the post back from the server.

I will research "setParameter() or addParameter() "...This should keep me busy. Thanks for the help.
