Translator

private Translator(String regExp)

Method Detail

translate

public static String translate(String regexp)
                        throws RegexSyntaxException

Translates a regular expression in the syntax of XML Schemas Part 2 into a regular expression in the syntax of java.util.regex.Pattern. The translation assumes that the string to be matched against the regex uses surrogate pairs correctly. If the string comes from XML content, a conforming XML parser will automatically check this; if the string comes from elsewhere, it may be necessary to check surrogate usage before matching.

Parameters:

regexp - a String containing a regular expression in the syntax of XML Schemas Part 2

Returns:

a String containing a regular expression in the syntax of java.util.regex.Pattern

Throws:

RegexSyntaxException - if regexp is not a regular expression in the syntax of XML Schemas Part 2
