I use my for-each to build up a string which is then passed to a template I call uniq. The parameter passed in looks something like: |z|a|b|c|a|b|c|b|b|y|z| That is, a "string list" with '|' as a separator. My uniq template uses the string functions substring-before, substring-after, & contains to recursively make that into a unique list. That's a lot of work for such a simple thing (simple in procedural languages). But at least I've got something working now. regards, Cliff Draper Sun Microsystems, Forte Tools (510) 869-3462 or x73462 My opinions may or may not reflect those of my employer. ---------------------------- food for thought --------------------------- The chief cause of problems is solutions.
