Question 1

How to handle XML namespaces with XMLCoder?

Accepted Answer

Set the shouldProcessNamespaces property to true on XMLDecoder to strip namespace prefixes during decoding, allowing key names to match your Codable types. This is demonstrated in the README with an example using xmlns attributes.

Question 2

XMLCoder vs SwiftyXML: which should I use?

Accepted Answer

XMLCoder is better for type-safe Codable integration and advanced features like Combine support, while SwiftyXML is simpler for basic parsing without Codable. Choose XMLCoder if you need robust encoding/decoding with Swift's native protocols.

Question 3

How to encode root element attributes in XMLCoder?

Accepted Answer

Use the rootAttributes parameter in the encode function to add custom attributes like xmlns declarations to the root element. The README shows an example with Policy struct and multiple namespace attributes.

Question 4

Does XMLCoder support XML schemas or validation?

Accepted Answer

No, XMLCoder focuses on encoding and decoding with Codable and does not include built-in validation against XML schemas or DTDs. You would need to handle validation separately using other libraries or custom logic.

Question 5

How to use property wrappers in XMLCoder for attribute mapping?

Accepted Answer

Use @Attribute, @Element, or @ElementAndAttribute property wrappers on Codable properties to concisely specify XML node types. Available from version 0.13.0, they reduce boilerplate compared to dynamic node coding protocols.

Question 6

Can XMLCoder handle enums with associated values in XML?

Accepted Answer

Yes, through XMLChoiceCodingKey protocol, allowing encoding and decoding of enums with associated values for choice elements. The README provides examples with IntOrString enum and nested complex types.
