Claus Ibsen commented on CAMEL-25481:
-------------------------------------
PR: https://github.com/apache/camel/pull/27612
Implemented phase 1 (XML input) and phase 2 (XML output):
* XML input: selectors match elements by local name (SOAP), ns directives and
.ns#name selectors, .@ and ..*, empty elements are null, object functions see
child elements in document order, and non-XML outputs no longer include the
DataSonnet XML model (attributes, xmlns, ~ positions).
* XML output: attributes key @(...), namespace-qualified keys, null as empty
element, arrays/object spreads/repeated keys as repeated elements in script
order, input elements written with their attributes and namespaces,
writeDeclaration and skipNullOn writer properties.
* 29 new corpus entries, all XML entries verified against the DataWeave CLI (dw
2.12).
Also found and fixed while testing: DataSonnet 3.0.1.3 does not memoize lazy
values (Val.Lazy.force uses a local lazy val), so every use of a function
argument re-evaluates it. Nested calls of camel-dataweave.libsonnet functions
were exponential in the nesting depth (e.g. 300 items through
map/filter/orderBy took over 120s, now 0.6s). The library functions now
evaluate their arguments once. This is worth reporting upstream to DataSonnet
as it affects plain DataSonnet scripts too.
