Dmitry,

Actually, I think now you have

document('')/*/trans:tr/tr_string[@str=$str]/*[name()=$toLang]"

Note the slight alteration in the predicate in the last step.

Then there is a question of which format would be faster for Xpath to
test to see if string exists in a desired language?

Beats me. I think examining the @lang attribute might be a tiny bit faster than using the name() function. I doubt the difference would be noticeable unless documents got very large.

I also think that the test using @lang is a bit more robust, however, in the face of possible browser bugs etc. But indexing using a key would also give you a potential performance boost too; and in that case a performance difference would probably disappear.

Cheers,
Wendell
