Class CharDataConversion

java.lang.Object
  hmi.xml.CharDataConversion

public class CharDataConversion
extends Object

CharDataConversion has methods to translate Strings (back and forth) into XML style CharData. The latter refers to the character data that occurs between XML tags: CharData , or as Attribute Value strings of the form : "text" or 'text'. Such character data and string texts cannot include the '<' and '&, characters, and, in the case of text strings, it cannot contain the string quote or apostrophe character. Moreover, XML CharData cannot include the pattern "]]>". CharDataConversion takes care of this: selected characters are replaced by XML entity references, such as "<", representing a "<" character. Unmarshalling carries out the reverse translation. Marshalling performs the following translations: '<' to "<", '>' to ">", '&' to "&", '"' to """, '\'' to "'". (Note that the sequence of the form "]]>" is therefore translated to "]]>").

Method Detail

encode

public static String encode(String value)

converts the String representation to the encoded XML representation. The latter uses XML entity references: "<"; for '<', ">" for '>', and "&" for '&' """ for '"', and "'" for '\''. The resulting external String can be safely used as CharData or attribute value in an XML text.

decode

public static String decode(String value)

converts the encoded XML representation to the 'normal' String representation. The former uses "<"; for '<', ">" for '>', and "&" for '&'; """ for '"', and "'" for '\''. these XML entity references are translated back to ordinary characters.
