 **jsoup.json** is a powerful JSON [RFC 4627](http://www.ietf.org/rfc/rfc4627.txt), 7158, [RFC 7159](http://www.ietf.org/rfc/rfc7159.txt) parser for jsoup.
 It can consume almost every text as JSON and convert it internally to an XML-tree.
 
+All JSON elements are converted one-to-one into three XML tags (obj, arr, val), XML comment section, (very rare and with many details) "unk" tag and two main attributes (id, class).

 No extra dependencies!
