failure to parse a specific WPS Execute document

[bartvde]

I am unable to parse the following WPS Execute XML with JSONIX, will try and investigate further:

Error occurs in:

                return callback(this.typeInfo.unmarshal(context, input));
            },

where typeInfo has no functions or properties.

The issue occurs as soon as a Body tag is a child of Reference

Thanks for the research, I'll take a look.

anyType is somehow not processed correctly. I'll investigate.

Please try the latest scripts:
https://github.com/highsource/jsonix/blob/master/nodejs/scripts/jsonix.js

This must be fixed now. I've added your XML as a test case:
https://github.com/highsource/jsonix/tree/master/nodejs/tests/wps

I've implemented the AnyType. You'll get a structure with attributes unmarshalled by anyAttribute (object with attributes) and content unmarshalled by anyElement (array of the values).

TODO document, will close the issue then.

[highsource]

Fixed in compiler 2.1.0/scripts 2.0.12:
https://github.com/highsource/ogc-schemas/tree/master/scripts/tests/WPS/1.0.0

Documentation still pending.

[bartvde]

I can confirm that parsing now works fine. Thanks for the fixes.

For serialising this type of document I'm still having an issue though, but it could be user error.

This is the XML that JSONIX generates:

Which results in:

This is the JSON string that I'm trying to serialise:

{"name":{"localPart":"Execute","namespaceURI":"http://www.opengis.net/wps/1.0.0"},"value":{"service":"WPS","version":"1.0.0","identifier":{"value":"geo:area"},"dataInputs":{"input":[{"identifier":{"value":"geom"},"reference":{"method":"POST","href":"http://geoserver/wps","mimeType":"text/xml; subtype=gml/3.1.1","body":{"content":[{"name":{"localPart":"Execute","namespaceURI":"http://www.opengis.net/wps/1.0.0"},"value":{"service":"WPS","version":"1.0.0","identifier":{"value":"geo:buffer"},"dataInputs":{"input":[{"identifier":{"value":"geom"},"data":{"complexData":{"mimeType":"application/wkt","content":["POLYGON((2805544.686179109 -682429.7885300545,4449246.542423539 -1386873.4412062382,2414187.101359006 -5378720.806371284,-325315.9923817087 -2717489.2295945873,2805544.686179109 -682429.7885300545))"]}}},{"identifier":{"value":"distance"},"data":{"literalData":{"value":"400000"}}}]},"responseForm":{"rawDataOutput":{"identifier":{"value":"result"},"mimeType":null}}}}]}}}]},"responseForm":{"rawDataOutput":{"identifier":{"value":"result"}}}}} 

[highsource]

Would you please try in a browser?
The p2 prefix for the attribute is missing. This might be a bug in xmldom string serialization of XML.

[bartvde]

I was trying this in Chrome (but have seen issues reported recently for OpenLayers as well), so will try Firefox

[bartvde]

Ah you're right, this is the Chrome bug, didn't realise this.

Works fine in Firefox.

[bartvde]

so: https://code.google.com/p/chromium/issues/detail?id=390879 and openlayers/openlayers#1359 are related

[highsource]

Interesting. Is it just xlink or namespaced attributes in general?

I'm not sure if it's xlink specific or not

[highsource]

Documentation:
http://confluence.highsource.org/display/JSNX/User+Guide#UserGuide-Definingenums
I'm closing this issue, please open a new one for namespaced attributes. I'll se what I can do.
