Nice work.
If you can parse a getCapabilities response, then there is a good chance
you are very close to being able to parse a Web Map Context (WMC)
document too. A WMC provides an XML list of WMS layers.
And if you go down this path, you might want to look at the Mapbuilder
code which has WMC parsing and OWS Context parsing too. OWS Context
includes layers from other sources too: GML, GeoRSS, WFS, etc.
Of note, it hasn't been approved by the OGC yet.
