How to merge two xml and xsl into one?

How to combine two xml and two xsl into one xsl?

Each XML have own XSL, but I want to call those xsl into one xsl.

The output that I need, its like, there's a question and there are three options

Option 1: Form1 Option 2: Form2 Option 3: Others

If the client choose option 1, the xml and xsl of form1 will be call and display. Or if the client choose option 2, the xml and xsl for form2 will be call and display.
