How can I use a Visual Web Part to pass a parameter to an XML Control in runtime?

Hi,

I need some guidance, please.

I have a Visual Web Part in VS2010 that queries a web service and returns an XML file.

How can I pass this XML to an XML Control on the same page in runtime?

I already set the 'TransformSource' parameter to my XSLT template file.

Basically, I want to query the web service, apply the XSLT on the fly to the XML and display the final result in the same page. In addition, I would like to:

Convert the HTML file to PDF
Save it a SharePoint library

How can I do that?

Thanks in advanced

you could use ajax to do asynchronous call to the service and handle the returned data using JSON or Linq.

As for the PFD conversion and SharePoint thats not my department lol but I'm sure someone else here can definitely help with that part.
