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.
