XSLT and XPath questions would be better posted to the following list:
http://www.mulberrytech.com/xsl/xsl-list
There are a number of subscribers who would enthusiastically respond to
such questions.
There is also an *excellent* FAQ at:

XSLT can be used for this.

Your very specific requirements can be met with ease, but I'm concerned
that you've not adequately described your true requirements ... I can only
work from your example.
>- indent the individual nodes properly in the resulting XML file
Indentation in XML is cosmetic. XSLT doesn't control indentation but
implementations of XSLT can provide indentation when requested. I ask
myself why you might be interested in indentation ... how does this help
your downstream processes?

An example is below that works with your data as supplied ... not sure if
it will address your general case since that is not well described. For
example, I have not accommodated any namespaces you might have in your real
data.
I hope this helps.

you are interested in going to the Island for some hands-on instruction.
