Add variables to XSL using JS

The operation is to add a variable to XSL using Js.
Then use this variable parameter in the XSL file.
---------------------------------------------
Eg:
1. In JS:
Xmldoc = new activexobject ('msxml2. domdocument.3.0 ')
Xmldoc. async = false;
Xmldoc. Load ("../XML/context. xml ")

// The style to be declared as a free-format Style
Export Doc = new activexobject ('msxml2. freethreadeddomdocument.3.0 ')
Optional Doc. async = false;
Using Doc. Load ("../XML/context. XSL ")

VaR oxslt = new activexobject ("msxml2.20.template. 3.0 ");
Oxslt. stylesheet = synchronized Doc;
VaR oxslproc = oxslt. createprocessor ();
Oxslproc. Input = xmldoc;
// Document. All. hidguid. value is a variable on the page.
Oxslproc. addparameter ("testvalue", document. All. hidguid. value );
Oxslproc. Transform ();
// Output information
Oxslproc. output;
2. In XSL, for example:
<XSL: Param name = "testvalue"/>
<XSL: template match = "entity">
<XSL: If test = "description! = ($ Testvalue) ">
......
</XSL: If>
</XSL: Template>
