Hi there!

I've been reading about XML and have the following doubt: Can XML be also used to represent methods/operations (behaviours) somehow, rather than just data/structure?

Thank you for your attention.

Regards,

Clever.

Well, given that methods/operations can be (and typical are) expressed as a syntax trees (regardless of the language involved), and given that a syntax tree is "just a data structure", yes, XML Is able to express any arbitrary data structure including one that represents a syntax tree that could be interpreted as a method/operation by some compiler/generator/transformer/interpreter.

Thank you for your reply, Ed!

Would you know any example of such an implementation (a URL)?

Regards,

Clever.

No, but if you export an Ecore model with EOperations to an XML Schema (via the GenModel for that Ecore model) those operations are represented in the *.xsd that's produced, so that's sort of an example, but it doesn't include syntax for the operation body. If the EOperation does have a body annotation, that's just serialized as text content. E.g., https://git.eclipse.org/c/emf/org.eclipse.emf.git/tree/plugins/org.eclipse.emf.ecore/model/Ecore.xsd#n238
