Subject: faq: operator precedence table? From: "Mark D. Anderson" <mda@xxxxxxxxxxxxxx> Date: Sun, 12 Dec 1999 15:43:03 -0800 |
except for a brief and incomplete list in xpath 3.4, i can find no comprehensive operator precedence table for xpath. if i had one i could tape it up on the wall next to the ones for C, java, perl, and javascript. one of the debits of not using list syntax (of the "<" or "(" variety) is that such things are necessary.... for example, something that would tell me which of these are the same: - a|b/c[1] - (a|b/c)[1] - (a|b)/c[1] and so on. the table is in order from least "tight", to most, with everything on the same row being left-associative. something like this, except i'm sure it is all incorrect: or and = != <=, <, >=, > div, mod ','(comma) +, - (binary) * (multiply) - (unary) | /, // [] $ :, ::, @, .., . (pattern), * (pattern) . (number) () ", ' thanks. -mda XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
