Class XmlNameEncoder

java.lang.Object

org.modeshape.common.text.XmlNameEncoder

All Implemented Interfaces:

TextDecoder, TextEncoder

@Immutable
public class XmlNameEncoder
extends Object
implements TextDecoder, TextEncoder

An encoder and decoder for XML element and attribute names.

Any UTF-16 unicode character that is not a valid XML name character according to the World Wide Web Consortium (W3C) Extensible Markup Language (XML) 1.0 (Fourth Edition) Recommendation is escaped as _xHHHH_, where HHHH stands for the four-digit hexadecimal UTF-16 unicode value for the character in the most significant bit first order. For example, the name "Customer_ID" is encoded as "Customer_x0020_ID".

Decoding transforms every _xHHHH_ encoding sequences back into the UTF-16 character. Note that decoding can be safely done on any XML name, even if the name does not contain any encoded sequences.
