Message-ID: Excerpt from the 3.13 of the XQuery 3.0 specification. "In a switch expression, the switch keyword is followed by an expression enclosed in parentheses, called the switch operand expression. This is the expression whose value is being compared." The issue is the last word - compared. XPath has general and value based comparisons and the spec doesn't say what type of comparison is operative for comparisons on the switch operand expression.

You cross posted to the wrong lists really, regex syntax is as defined by schema, not by xsl or xquery, and that defines \w as [#x0000-#x10FFFF]-[\p{P}\p{Z}\p{C}] (all characters except the set of "punctuation", "separator" and "other" characters) By backtick I assume you mean U+0060 [`] which isn't a quotation mark, it's a grave accent and has unicode class Sk so isn't punctuation, separator or other.

I almost said it was amazing how you can simultaneously hold both positions in the course of one reply but actually it's not. Look if your primary objective was a professional one then the observation to have made in this thread (which someone else already did) is that there seems to be a buggy XQuery implementation at play here. Because if a stream of ones is the correct response and thats what is returned then what happened to cause that is immediately apparent. You on the other hand harbour the pathetically juvenile viewpoint that the scenario offered an opportunity to come on here and josh d**ks. Why? Maybe you were the puny kid at school who used smarts at other peoples expense instead of fists to build self esteem. That stops working when l you come across a kid who is both bigger and smarter. While we are on the subject of childhoods, you know all those kids who say "My mother told me that if you can't say something nice about someone you shouldn't say anything at all".

I tried MarkLogic once but I wasn't smart enough to work it :) although years ago I also used Galax and, until a year or so, qizx. Actually I still use qizx/open for some things on www.fromoldbooks.org because it's so fast and I haven't found time to move those queries to basex.
