Reader Namespaces at the current level

[jose-pr]

I would like to suggest two functions be added to the reader

• Add a function to resolve a prefix to a namespace, currently you need a qname (prefix+":"+name)
• Add a function to get an iterator or vec of all the current namespaces, returning (ns_prefix, ns_uri)

Would you mind writing a PR?

I'm curious. Is the mapping of the namespace alias to the canonical URI stored anywhere currently? If so, does that storage method allow reassigning aliases in child levels?

Yes, of course: https://github.com/tafia/quick-xml/blob/add740632a62e0cfdef022e0bdf960009f63f611/src/reader/ns_reader.rs#L27-L28

Yes, see the implementation of this struct: https://github.com/tafia/quick-xml/blob/add740632a62e0cfdef022e0bdf960009f63f611/src/name.rs#L390-L400
