Thanks, this seems workable ... however i am restricted to using XPath
1.0 so the 'except' operator is out of the window.
So i guess, I simply have to run the 2 Xpaths on either side of the
'except' individually and filter the nodes of the right hand side
from the left hand side via the dom API ?
I wouldn't have approached it that way ... I would have tried to come
up with an XPath address that only addressed the nodes desired.
I haven't tested the following on your data, but if the current node
is the <text:change-start> element then I believe this will find all
text nodes up until the <text:change-end> element with the same
identifier using XPath 1:
following::text()[preceding::text:change-start[1]/@id=current()/@id and
not(preceding::text:change-end[1]/@id=current()/@id)]
I try to remind my students that the more work you can do addressing
the nodes you want, the less work you'll have to do trying to get rid
of the ones you don't want. Which gives the processor more
opportunity to optimize the finding of the nodes you do want.
I hope this helps.
