add xml_node_type_str function for debugging and application logging about pugixml HOT 3 CLOSED

Do you need this often? This seems like it's not something that should be useful super frequently because you either know the expected type of a given node or, if you're writing a function that expects arbitrary node types, you'd need to process the rest of the node data in a way that depend on the type (eg elements have names, pcdata nodes have values) in which case I'm not sure a function like the above is super helpful.

Yes and no. I use it mainly for tracing/debugging during development and think it is very handy. If I would write generic function I would use direct xml_node_type for switching/ifelse instead of the text based version, agreed anything else wouldn't be very plausible.

Ok - this feels like something that's very easy to provide in a separate header, and doesn't obviously match any other existing functionality in pugixml so it would probably make sense to keep it separate.
