XML Parsing infinite loop

[MarlinKuhn]

Hey,

there is currently a bug inside the nbio/xml library, that creates an infinite loop when parsing specific invoices that contain the character > inside of any Field e.g. Description or Notes. But that is valid for a XML in general.
Since nbio/xml is a fork of the default encoding/xml package in go (where the bug was fixed), I created a fork of the lib and a PR nbio/xml#21 but until they merge it I would suggest using my fork https://github.com/MarlinKuhn/xml

I attach a valid XML Invoice directly from DATEV wich contains html in descriptions.
