[xsl] Using operators >> and <<

["Ylvisaker, Steve" <steve.j.ylvisaker@xxxxxxxxxxxxx>]

I am working on a frame to XML conversion. The frame file is flat leading to
several challenges. I have used for-each-group with attribute
group-starting-with to unflatten the document sections. However, I have a
different challenge to address. I need to take the following markup:

<para>a para of data</para>
<bullet>first bullet data</bullet>
<bullet>second bullet data</bullet>
<bullet>third bullet data</bullet>
<para>more para data</para>
<bullet>another bullet list</bullet>

And turn it into:
<ulist>
  <listitem><para>first bullet data</para></listitem>
  <listitem><para>second bullet data</para></listitem>
  <listitem><para>third bullet data</para></listitem>
</ulist>

It is easy enough to identify and format the <ulist/> based on the occurrence
of the first <bullet/> but then isolating just the remaining contiguous
bullets eludes me. I have the feeling that I can use the << or >> operators to
select all of the bullets until the node name changes in the document order.
However, I can only find very sketchy documentation regarding these constructs
and when I try to use them I get syntax errors.

Any suggestions or pointers on where I could look for working examples (not
shorthand) of how these constructs can be used or suggestions on a different
approach would be very much appreciated.
