Improve support for XML lists

[ofrias]

Hello. I understand that Jackson 3 plans to better support formats other than JSON. In particular, for XML, it would be nice to have a method like JsonNode.getArray(String element) to get XML node lists in ArrayNode format automatically, even for 1 element lists which are currenty returned by JsonNode.get("element") as an ObjectNode. For more context please see this SO question. Thanks!

Thank you for your suggestion. We can consider something like this (getAsArray() perhaps). But it cannot quite be XML-specific, altho this could be generally useful across data formats.
