Root level attributes don't get encoded back to attribute when converting back to XML file from Plist

[MehmetBal]

Hi,

First of all thanks for creating such a useful library! I am having a bit of a hard time with root-level attribute encoding.

I have a complex XML that requires a big model but to simply:

To decode something this:

<?xml version="1.0" encoding="UTF-8"?>
<policy name = "..." attr2="...">
   <Initial>
    more xml here
     .....
     ....
  </Initial>
</policy>

I am doing

struct Policy: Codable, Equatable, DynamicNodeEncoding {
    var name: String
    var initial: Initial
enum CodingKeys: String, CodingKey {
        case name,  initial
    }

static func nodeEncoding(for key: CodingKey) -> XMLEncoder.NodeEncoding {
        switch key {
        case CodingKeys.name
            return .attribute
        default:
            return .element
        }
    }
}

Then I decode using XMLDecoder(), encode to PLIST using PropertyListEncoder() then encode back to XML with first PropertyListDecoder() and then

            let data = try encoder.encode(modifiedData, withRootKey: "policy",
                                          header: XMLHeader(version: 1.0,
                                                            encoding: "UTF-8"))

and everything works gets encoded properly except the root level attributes.
The result becomes:

<policy><name>generic</name>
<initial>
   .....
   .....
</initial>
</policy>

I tried .both instead of just encoding as .attribute but that did not make a difference.

Any ideas on how to fix this?

Thanks

Hi @MehmetBal, can you please have a look at #134? We aren't able to reproduce the issue with the test added in that PR. Is there anything missing that should be added to the test to reproduce this?

This issue hasn't been updated for more than a few months, I'm assuming it can be closed as outdated.
