Hi,

I have an URL Structure like this:

 http://my.domain.com/generated.xml?param1=foo&param2=bar&xsl=path/to/my.xsl

The generated XML will be transformed using the given XSL Stylesheet. The two other parameters are integrated too like this:

<root>
  <params>
    <param name="param1">foo</param>
    <param name="param2">bar</param>
  </param>
  ...
</root>

Now I want to create with XSLT a link with a new URI that keeps the existing parameters and adds one or multiple new parameters like page=3 or sort=DESC. If the given parameter already exists, it should be replaced.

I'm not sure how to do this. How to pass multiple (optional) parameters to a template. How to merge two lists of parameters.

Any ideas?

Thanks ;)
