All Implemented Interfaces:

EncodingDetector

public class XMLEncodingDetector
extends XMLParseState
implements EncodingDetector

This is the XML encoding detector. It is basically looking for the preamble's <?xml ... ?> tag, which it parses looking for the "encoding" attribute. It stops either when it is beyond any possibility of finding the preamble, or it finds the tag, whichever comes first.
