The `goxpp` library is an XML parser library that is loosely based on the [Java XMLPullParser](http://www.xmlpull.org/v1/download/unpacked/doc/quick_intro.html). This library allows you to easily parse arbitary XML content using a pull parser. You can think of `goxpp` as a lightweight wrapper around Go's XML `Decoder` that provides a set of functions that make it easier to parse XML content than using the raw decoder itself.
