---------------------------
Resolution: Won't Fix
> Javascript engine (Nashorn) doesn't support native XML DOM operations
> ----------------------------------------------------------------------
>
> Key: SCXML-272
> URL: https://issues.apache.org/jira/browse/SCXML-272
> Project: Commons SCXML
> Issue Type: Improvement
> Affects Versions: 2.0
> Reporter: Ate Douma
>
> While the Groovy and Jexl datamodels, being 'native' Java engine, can be used
> for XML DOM operations with <assign> and evaluation expressions, this doesn't
> work with the Nashorn Javascript egnine.
> There simply is no Javascript DOM operation support in Nashorn, and there
> also doesn't seem to be an (practical) extension or something available
> elsewhere.
> As a consequence, Commons SCXML cannot fully implement the SCXML mandatory
> features for the ecma datamodel.
> This also is the cause of failure for 2 out of the last 3 non-passing [W3C
> SCXML IRP|https://www.w3.org/Voice/2013/scxml-irp/] tests (186 tests total):
> # [test557|https://www.w3.org/Voice/2013/scxml-irp/557/test557.txml]
> # [test561|https://www.w3.org/Voice/2013/scxml-irp/561/test561.txml]
> both testing a similar expression like:
> {code:java}cond="var1.getElementsByTagName('book')[0].getAttribute('title')
> == 'title1'"{code}
> which simply fails to execute in Nashorn Javascript.
> Both the Jexl and Groovy datamodels have no problem evaluating the above.
> Note that ecma datamodel support itself is optionally, but *if* it is
> supported *then* mandatory tests like the above should pass.
> As finding a practical solution or fix for this seems unlikely, I'm just
> reporting this here, but will close as Won't Fix (can't reallly).
