XML Schema should support Variant Attributes

[gb119]

In the current LabVIEW XML Schema, the flatten to XML string supports variants, but not variant attributes (and by extension waveform attributes as well). This is unfortunate as variant attributes remain one of the best ways of implementing a dictionary type data structure and they are also a useful way of adding additional metadata to waveform signals. In both cases, serializing the attributes to XML strings properly would greatly facilitate data exchange with non LabVIEW code.

Oh yes.  This has annoyed me on at least eleven non-consecutive occasions.

For what it's worth, you should be able to get all the variant attributes as an array of variants by leaving the "name" control disconnected, then you can push each of them into a Write to XML function in a FOR loop. Reverse the process for reading them back out to populate your dictionary.

Just to note that the LV2019 map type is in the xml schema (but not the json schema) and has many of the benefots of the variant attributes.

gb119 is correct. We did this in LV2019. I didn't realize there was an idea for this.

Available in LabVIEW 2019 and later.

Well there you go, another user contributed idea implemented - even if inadvertantly.... any chance of getting the json serializer working too?
