Description

Interface Summary

RegexIterator	This class is an interator that supports the evaluation of xsl:analyze-string.
RegularExpression	This interface represents a compiled regular expression

Class Summary

CaseVariants	This class holds data about the case-variants of Unicode characters.
RegexData	Non-instantiable class containing constant data definitions used by the various Regular Expression translators
RegexTranslator	Abstract superclass for the various regex translators, which differ according to the target platform.
RegexTranslator.Range	A Range represents a range of consecutive Unicode codepoints
SurrogateRegexTranslator	Abstract superclass for the JDK 1.4 and .NET regex translators, or in principle for any other target regex dialect in which "." matches a UTF-16 16-bit code rather than a Unicode character
SurrogateRegexTranslator.BackReference	Character class representing a back-reference.
SurrogateRegexTranslator.CharClass	Object representing a character class
SurrogateRegexTranslator.CharRange	Character class that matches any character within a range of codepoints
SurrogateRegexTranslator.Complement	Character class representing the complement of another character class, that is, all characters that the other class doesn't match.
SurrogateRegexTranslator.Dot	Character class representing the characters matched by the XPath "." metacharacter
SurrogateRegexTranslator.Empty	Character class that matches nothing
SurrogateRegexTranslator.Property	Character class containing characters that share a given Unicode property
SurrogateRegexTranslator.SimpleCharClass	Simple Character Class - essentially, anything other than a Union or Subtraction between two character classes.
SurrogateRegexTranslator.SingleChar	Character class that matches a single specific character in the BMP
SurrogateRegexTranslator.WideSingleChar	Character class that matches a single specific character outside the BMP

Exception Summary

RegexSyntaxException

Thrown when an syntactically incorrect regular expression is detected.

Package net.sf.saxon.regex Description

This package contains the code to map XML Schema and XPath regular expressions to the regular expression engine of the underlying Java platform.

Regular expressions are translated into the form accepted by JDK 1.5 or JDK 1.4. There are two separate versions of the translator because these two platforms differ radically in how Unicode characters outside the basic multilingual plane are handled.

Users should not normally need to use these classes directly.

Most of the code used in these translators was developed originally by James Clark.
