Interface RegularExpression

All Superinterfaces:

Serializable

All Known Implementing Classes:

JRegularExpression

public interface RegularExpression
extends Serializable

This interface represents a compiled regular expression

Field Summary

static int	NATIVE_SYNTAX Constant indicating the regular expression syntax is the native syntax for the platform (Java or .NET)
static int	XML_SCHEMA_SYNTAX Constant indication the regular expression language is XML Schema Part 2
static int	XPATH_SYNTAX Constant indicating the regular expression language is XPath 2.0

Method Summary

RegexIterator	analyze(CharSequence input) Use this regular expression to analyze an input string, in support of the XSLT analyze-string instruction.
boolean	containsMatch(CharSequence input) Determine whether the regular expression contains a match of a given string
boolean	matches(CharSequence input) Determine whether the regular expression match a given string in its entirety
CharSequence	replace(CharSequence input, CharSequence replacement) Replace all substrings of a supplied input string that match the regular expression with a replacement string.
SequenceIterator	tokenize(CharSequence input) Use this regular expression to tokenize an input string.

Method Detail

matches

boolean matches(CharSequence input)

Determine whether the regular expression match a given string in its entirety

Parameters:

input - the string to match

Returns:

true if the string matches, false otherwise

containsMatch

boolean containsMatch(CharSequence input)

Determine whether the regular expression contains a match of a given string

Parameters:

input - the string to match

Returns:

true if the string matches, false otherwise

tokenize

SequenceIterator tokenize(CharSequence input)

Use this regular expression to tokenize an input string.

Parameters:

input - the string to be tokenized

Returns:

a SequenceIterator containing the resulting tokens, as objects of type StringValue

analyze

RegexIterator analyze(CharSequence input)

Use this regular expression to analyze an input string, in support of the XSLT analyze-string instruction. The resulting RegexIterator provides both the matching and non-matching substrings, and allows them to be distinguished. It also provides access to matched subgroups.

Parameters:

input - the character string to be analyzed using the regular expression

Returns:

an iterator over matched and unmatched substrings

replace

CharSequence replace(CharSequence input,
                     CharSequence replacement)
                     throws XPathException

Replace all substrings of a supplied input string that match the regular expression with a replacement string.

Parameters:

input - the input string on which replacements are to be performed

replacement - the replacement string in the format of the XPath replace() function

Returns:

the result of performing the replacement

Throws:

XPathException - if the replacement string is invalid
