Hi Dave, > the problem is now that the template below never > fires the otherwise clause of the choose, and I can't see why. The only reason I can see why the xsl:otherwise wouldn't be fired is if the $auths variable always gets set to a node set that contains some nodes. That would be true if within your document you have at least one r element with a Ra/lett equal to each letter of the alphabet. Which could be the case - it's impossible to tell without seeing your document. Note that the way you have it at the moment, it's perfectly possible for the xsl:when clause to be selected but you to see no output from it. When you do: > <xsl:when test="$auths/node()"> > <xsl:apply-templates select="r[generate-id(.)= > generate-id(key('auth',Ra/lett)[1])]"/> > </xsl:when> Then you're only applying templates to the r element children of the current adventure that happen to be the first such r elements in the document as a whole with that letter in their Ra/lett grandchild. In fact, the path you're using there is exceedingly strange, since it will give you the same thing on each recursion, but I guess you're doing that on purpose?
