You need to escape the << to &-l-t-; &-l-t-; (dashes added for clarity, remove in code).
You might want to escape >> to &-g-t-; &-g-t-; as well.

The below statement works fine when I run a XQUERY against my XML. It returns the nodes that I need.

for $T1 in (//title)[1], $T2 in (//title)[2] return ($T1, //*[. >> $T1 and . << $T2], $T2)

However, when I plug it into a XSLT template it complains about the >>,<< characters. I have tried different versions of them but none validate.

<xsl:template match="for $T1 in (//title)[1], $T2 in (//title)[2] return ($T1, //*[. >> $T1 and . << $T2], $T2)">

<xsl:element name="sect1">

Any suggestions?

Is it possible to use Xpath to select a range of nodes.


I would like an Xpath statement that would select //title[1]
THROUGH //title[2] and include all nodes between.  Is this possible?

I'm assuming that <para> represents <para>....</para>, i.e. a complete element.

If you know that the nodes are siblings, and you are positioned on their
parent, then you can do

(title[1] , *[. >> title[1] and . << title[2]] , title[2])

If they aren't siblings and you are positioned on the root, then you can do

for $T1 in (//title)[1], $T2 in (//title)[2]
return ($T1, //*[. >> $T1 and . << $T2], $T2)

That's XPath 2.0; in 1.0 it's more tricky.
