Ugh, my apologies. I didn't send a complete example which shows the problem I'm trying to solve. The feature can contain multiple configs, each of which I want to merge across features: <?xml version="1.0"?> <config_datastore> <feature name="a"> <config id="1"> <param id="x">x</param> </config> <config id="2"> <param id="xx">xx</param> </config> <config id="3"> <param id="xxx">xxx</param> </config> </feature> <feature name="b"> <config id="1"> <param id="y">y</param> </config> <config id="2"> <param id="yy">yy</param> </config> </feature> <feature name="c"> <config id="1"> <param id="z">z</param> </config> <config id="2"> <param id="zz">zz</param> </config> </feature> <site> <has_feature name="a"/> <has_feature name="c"/> </site> </config_datastore> I want to be able to select /config_datastore/site/* and perform selective grouping (on feature @name) and merging (on the feature/config elements) to return: <config id="1"> <param id="x">x</param> <param id="z">z</param> </config> <config id="2"> <param id="xx">x</param> <param id="zz">z</param> </config> <config id="3"> <param id="xxx">xxx</param> </config> The tree fragment example I posted shows essentially what I have now, I can grab the each major config set, but I then want to perform a merge. The example I posted makes it look like I could just run <xsl:copy-of select="key('feature', @name)/config/*"/> but I can't, because each config has it's own uniqueness (id 1, id 2, id 3, etc.). I'll go get some coffee now before I try and post again. Jim - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - James A.
