Oh I see. I had always thought that node() would select an actual node or
text. Didn't think it would select blank spaces. My source document is
pretty big and I can see that my previous version didn't grab particular
content.
Thank you!

Subject: RE: [xsl] Selecting First Direct Sibling
following-sibling::node()[1][self::comment()]
selects the following sibling node if it is a comment.
If there's a whitespace text node in between the context node and the
comment, following-sibling::node()[1] will be a text node, so nothing will
be selected.
So it's a good idea to get rid of whitespace text nodes using strip-space.
