Re: [basex-talk] How to extract value from fn:analyze-string
Gerrit!
You wound me - I'm cut to the very core :)
For the life of me, I couldn't remember if the `fn` prefix was correct or
not.
@Ben - Gerrit's absolutely right - wildcards are desperate measures (or for
quick, one-off scripts). Using the namespace is much preferable.
Best,
Bridger

Re: [basex-talk] How to extract value from fn:analyze-string
I'll experiment a little with the namespace but for the moment adding *:
works!
Thanks,

Whereas you don’t need to use the privileged fn prefix when you invoke
analyze-string(), it’s only important when you select the namespaced
results.

I am trying to extract the values from group 1 and 2 but this query
returns 0 results:
let $debates := collection("Parliament")
for $debate-item in $debates
let $item-file := $debate-item/officiele-publicatie//meta/@content
let $debate-id := fn:analyze-string(
$debate-item/officiele-publicatie//meta/@content,
"(\d{8}-\d*)-(\d*)")
let $debate-nr := $debate-id//match/group[@nr="1"]/text()
let $item-nr := $debate-id//match/group[@nr="2"]/text()
return ($debate-nr, $item-nr)
My guess is that analyze-string inserts new elements in the query and
that that is the reason why this does not work.
How can I extract debate-nr and item-nr from $debate-id?

Re: [basex-talk] How to extract value from fn:analyze-string
It’s a namespace thing. The analyze-string() result is in the
http://www.w3.org/2005/xpath-functions namespace, which is bound to the
fn prefix. So you should write fn:match etc. instead of match, or, as
Bridger suggested, *:match. But such a wildcard always seems a bit
desperate to me (no offense, Bridger ;).

How can I extract debate-nr and item-nr from $debate-id?

Re: [basex-talk] How to extract value from fn:analyze-string
Include the namespace, or put in a wildcard; eg
let $debate-nr := $debate-id//*:match/*:group[@nr="1"]/text()
let $item-nr := $debate-id//*:match/*:group[@nr="2"]/text()
I'm mobile at the moment, but think that's right (: untested and off the
cuff, in other words :).
