 Description   

Сurrently there is preprocessing XPath and JSONPath. If you need to implement something more complex, then Javascript is used. But if the input data is XML, then in Javascript it is impossible to perform further processing of elements (after XPath preprocessing or without), since there is no XML-parser in JS prepocessing.
It would be very convenient to add either XML to JSON rule, or support library for XML-parsing in JS preprocessing.

Supporting XML-parsing in JS would be quite complex task. The simplest way would be adding XML->JSON->XML conversion to JS (not a new preprocessing step). This way it could be also used by webhooks. However there is no straightforward conversion possible, some translation rules would need to be set.

Dear Andris Zeila, it is possible to give the user the opportunity to choose the method of XML to JSON conversion (for example, to convert the attributes of a node as a field of JSON or nested array, etc.)

Maybe it is possible to implement an API to add custom C modules to the preprocessing chain? That would be a solution to the problem. ZBXNEXT-5523
