This is a completely standard grouping problem. Grouping is much easier in
XSLT 2.0 using xsl:for-each-group, but if you really need to stick with 1.0,
go to http://www.jenitennison.com/xslt/grouping to learn how to do it.

This code:

string-length(category) != string-length(following::category)

is wildly out.

And why do you want to disable-output-escaping?
