I've been playing a bit with BaseX the last couple of days - and very
excited about the product while doing so - but now I am having problems
outputting JSON from a PHP script.
I have this XQuery:
declare option output:method json;
declare option output:json format=jsonml;
json type=object
{
Hi Paul,
Which is what I expected after reading about the JSONML format. (Not too
happy with that format, but that's another story).
I agree; JSONML is a quasi-standard we have adopted, which is mainly useful
for converting arbitrary XML to JSON. If you can decide how your XML format
looks
Hi Christian,
Thanks for the quick answer.
Unfortunately your proposed solution (json:serialize) does not work in
this case; BaseX returns a BXJS0002 error:
JSON serializer: found, _ expected.
The modified query reads:
json:serialize(
json type=array objects='_'{
for \$user in
I should have run your query before sending you an answer. The
following query should work:
json:serialize(
json type=array objects='_'{
for $user in
collection(saveresult)//user[_id=1f2cda8f-a18a-44ba-8d17-73626d472306]
return
_
testId{$user/test/_id}/testId
Hello,
If distributed storage implemented via NFS (Network file system), the answer
should be yes. For example, folder /opt/strage/data1/. maps to server1,
another folder /opt/storage/data2/. maps to server2, distributed query
might look like this:
let $A :=
Still no luck:
JSON serializer: testId is typed as string and cannot be nested
I think I am going to move the JSON conversion to within PHP or
Javascript, and keep the XQueries clean and readable.
Paul
json:serialize(
json type=array objects='_'{
for $user in
Hi Paul,
no need to despair ;)
The default JSON converter is the direct one (which would require
testId/ to be declared an object), not JsonML. If you you want to use
JsonML you can do so by using
json:serialize(
json type=array objects='_'{
for $user in
Hello Chen,
at the moment, the answer to this question is still no. We are working
into this direction, but we are not production ready.
As Sergey outlines you can of course use a distributed file system as
basis for BaseX.
Cheers,
Dirk

Hello,
Ah, yes, that did the trick. I read about the options but had forgotten
about it.
Thanks.
I will run some performance tests to decide for json:serialize or PHP
internal conversion which might be considerably slower.

Hi Paul, and thanks Dirk.
One last note: If you plan to stick with JsonML, you can serialize
arbitrary XML data, such as..
json:serialize(
xml{
for $user in
collection(saveresult)//user[_id=1f2cda8f-a18a-44ba-8d17-73626d472306]
return
