SVG and dynamic XML data source

Hi all,

I'm looking for information on inserting XML data into an existing SVG document and ensuring that I can use SVG DOM to create mouseover/onclick events.

I will have an SVG document with base mapping and I want the user to select a layer to query, but that layer will contain information/coordinate detail in XML format. So when the user selects the appropriate layer it all comes together. I can do all this with hardcoded data, but I want the option of being able to dynamically call XML data into an SVG document.

I think of got the hang of XSL/XSLT for standard XML documents, but frankly I get a bit lost trying to integrate this with SVG docs.

Does anyone know of tutorials/articles that could help me please?

Thank you,
Ben
