Re: [basex-talk] RESTXQ and regexp

[Christian Grün]

Hi Marco,

I can confirm that your RESTXQ paths were supposed to work as you
expected them to work: If more than one endpoint is found in the first
round, the one with a larger number of path segments should have been
selected as favorite. In our implementation, the one with less
segments was chosen, which is why your page:others function was
evaluated in all cases.

I have corrected this behavior; the latest snapshot should work as
expected. In addition, I have slightly revised our documentation.

Cheers
Christian

Thanks for your suggestion Liam!
We've tried this out on the current deployment which involves version 
8.6.3 and it didn't fix our specific use case.
My idea here (I'm not sure to make the correct assumption though) is 
that the proposition "if multiple candidate functions ar eleft over" 
stated in the docs is not holding here.
It rather looks as if BaseX is considering only the more generic one to 
match.

Regards,
Marco.

Can you use content negotiation/quality to say the /input one is
preferred when both match? E.g. %rest:produces("*/*;qs=0.8") on the
page:others function and */*;qs=1.0 on the input ont?

[basex-talk] RESTXQ and regexp

[Marco Lettere]

Hello all,

according to the docs this should be possible:

(: Matches all paths with "app" as first, a number as second, and 
"order" as third segment :)

declare %rest:path("app/{$code=[0-9]+}/order")
  function page:order($full-path) { ... };

(: Matches all other all paths starting with "app/" :)
declare %rest:path("app/{$path=.+}")
  function page:others($path) { ... };

And it actually is... We are currently in the very unfortunate situation 
where we need the following:


(: Matches anything followed by /input :)
declare %rest:path("app/{$path=.+}/input")
  function page:inputs($path) { ... };

(: Matches all other all paths starting with "app/" :)
declare %rest:path("app/{$path=.+}")
  function page:others($path) { ... };

Unfortunately this makes all the calls to be redirected to the 
page:others function ... is there a motivation behind it or could it be 
possible to work around that?


Thanks,

Marco.
