```
public class JDK15RegexTranslator
extends RegexTranslator
```
This class translates XML Schema regex syntax into JDK 1.5 regex syntax. This differs from the JDK 1.4 translator because JDK 1.5 handles non-BMP characters (wide characters) in places where JDK 1.4 does not, for example in a range such as [X-Y]. This enables much of the code from the 1.4 translator to be removed. Author: James Clark, Thai Open Source Software Center Ltd. See statement at end of file. Modified by Michael Kay (a) to integrate the code into Saxon, and (b) to support XPath additions to the XML Schema regex syntax. This version also removes most of the complexities of handling non-BMP characters, since JDK 1.5 handles these natively.

public static java.lang.String translate(java.lang.CharSequence regExp,
                                         int xmlVersion,
                                         boolean xpath,

                                  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:
    
    xmlVersion - set to Configuration.XML10 for XML 1.0 or Configuration.XML11 for XML 1.1
    
    regExp - a String containing a regular expression in the syntax of XML Schemas Part 2
    
    xpath - a boolean indicating whether the XPath 2.0 F+O extensions to the schema regex syntax are permitted
    
    ignoreWhitespace - true if whitespace is to be ignored ('x' flag)
    
    caseBlind - true if case is to be ignored ('i' flag)
    
    Returns:
    
    a JDK 1.5 regular expression
    
    Throws:
    
    RegexSyntaxException - if regexp is not a regular expression in the syntax of XML Schemas Part 2, or XPath 2.0, as appropriate

```
public static void main(java.lang.String[] args)
                 throws RegexSyntaxException
```
    Main method for testing. Outputs to System.err the Java translation of a supplied regular expression
    
    Parameters:
    
    args - command line arguments arg[0] a regular expression arg[1] = xpath to invoke the XPath rules
    
    Throws:
    
    RegexSyntaxException
