Replace DOMParser with SimpleXMLParser
The `DOMParser` is most likely overkill and may be less secure.
Moreover, it is not supported in Node.js environments.

This patch replaces the `DOMParser` with a simple XML parser. This
should be faster and gives us Node.js support for free. The simple XML
parser is a port of the one that existed in the examples folder with a
small regex fix to make the parsing work correctly.

The unit tests are extended for increased test coverage of the metadata
code. The new method `getAll` is provided so the example does not have
to access internal properties of the object anymore.
