Re: [docbook-apps] multiple xreferences: [1,2,3] and [4]

["Bob Stayton" <bobs@sagehill.net>]

Hi,
If you want to test if an xref is immediately preceded by another xref, 
then this test should work:

test="preceding-sibling::node()[1][self::xref]"

The node() selector lumps together text nodes, comments, elements, and 
processing instructions, so the first step selects preceding sibling nodes 
of all types.  The [1] selects the closest one, and the [self::xref] tests 
to see if the selected node is an xref element.

The xref has to be immediately preceding, with no white space, not even a 
line feed between them.
