Hi all,
Forgive me. Rather than post more code in this thread, I've created a
gist with revised code that resolves some inconsistencies in what I
posted here earlier.

Again, this isn't a full-featured CSV parser by any means; it
And corrected query body:

Sorry, a typo crept in. Here's the corrected function:
declare function local:get-cells($row as xs:string) as xs:string {

let $string-to-analyze := $row || ","
let $analyze := fn:analyze-string($string-to-analyze,
Hi Christian,
Yes, that sounds like the culprit. Searching back through my files,
Adam Retter responded on exist-open (at
http://markmail.org/message/3bxz55du3hl6arpr) to a call for help with
the lack of lookahead support in XPath, by pointing to an XSLT he
adapted for CSV parsing,

I assume it’s the lookbehind assertion that is not allowed in XQuery
(but I should definitely spend more ti
Hi all,
Christian: I completely agree, CSV is a nightmare. One way to reduce
the headaches (in, say, developing an EXPath CSV library) might be to
require that CSV pass validation by a tool such as
http://digital-preservation.github.io/csv-validator/. Adam Retter
presented his work on CSV Schema
I didn’t check the regex in general, but one reason I think why it
fails is the escaped quote. For example, the following query is
illegal in XQuery 3.1…
matches('a"b', 'a\"b')
…where as the following one is ok:
matches('a"b', 'a"b')

Cordial thanks, Liam - I was not aware of that!
@Joe: Rule of life: when one is especially sure to be right, one is surely
wrong, and so was I, and right were you(r first two characters).
