How can JSON be transformed into XML if the JSON key contains a colon, which is not permitted in XML?

edit

If a JSON key contains a colon, it can be transformed into XML by replacing the colon with an underscore or a hyphen. This is because XML does not allow colons in its element names, but allows underscores and hyphens. For example, if the JSON key is "firstname:lastname", it can be transformed into "firstnamelast_name" or "first-name-last-name" in XML. This can be done using a programming language or a tool that supports JSON to XML conversion.
