Help with squonk63's simple XSL

I have used squonk63's XML export to create an XML-file for my entire music collection.

Since the collection is quite big, I would like to split the display into webpages for example for all artist starting with 'B'.

  • Similar to the way allofmp3/mp3sparks display's their collection

I do not want to produce separate XML files, but would prefer to filter this out with the XSL file/template.

My problem is that I don't know XSL, and I need help modifying squonk63's simple XSL file to only display for example all artists with a name starting with 'B'
