XML export / import

[llogiq]

Required Functionality
A new export strategy and import to and from XML files.

Proposed Solution
Exporting to a simple XML file with the namespaces and fields as entities containing the values as text. XSLT can then be used to mangle that to the desired format as a first 80% solution.

Use case
Some people are still working with XML based tools. An export would make it easier for them to work with synth.

I have wrote the yaserde librairie, I think it can be very useful to support that feature !

@MarcAntoine-Arnaud - could you point me in the right direction here?

The part I'm not sure how to think about is how we would map fields in synth to attributes in XML.

Hello,

As you can see here: https://github.com/media-io/yaserde/blob/master/examples/src/bbigras_namespace.rs
You can manage attribute at import/export.
It supports also namespaces and all features of XML. All think that Serde don't wanna to support as it's too specific to XML.
