> Q1: Is there a performance penalty for either design? Possibly but yougave no indication of what you are doing. If you arejust listing the file, then any design is essentially equivalent. If you are doing a transfromation, then some designs are better than others for some kinds of transformation. > Q2: Does the answer depend on the XSLT processor? Fine details will depend on system optimisations etc, but broad design doesn't usually. In particualar if you need to process your model names individually your eleemnt based designe is likely to be better as any xpath engine ought to be pretty well optiomised to iterate over models/model but if your models are a space sparated string in an attribute value, XSLT1 has essentially no basic capability to handle those tokens and so you need to write a recursive iteration based on substring-before, which is likely to be a lot slower.
