And, because of the phonetic rules, you use "an". As in "An Ecks-Em-Ell editor". It's all about vocal pronounciation. If you pronounced "XML" as "ksml", then, sure, you would use "a" - but I don't have any idea on how to form that sound, and everyone I know pronounces "XML" by saying each letter seperately, leaving us with the leading "e" sound from "X".

    And for the exact same reason, it is proper to write "a URL", not "an URL" (unless, of course, you're a non-geek and you pronounce it "earl").
