Interface RegexIterator

All Superinterfaces:

SequenceIterator

All Known Implementing Classes:

JRegexIterator

public interface RegexIterator
extends SequenceIterator

This class is an interator that supports the evaluation of xsl:analyze-string. It returns all the matching and non-matching substrings in an input string, and provides access to their captured groups

Field Summary

GROUNDED, LAST_POSITION_FINDER, LOOKAHEAD

Method Summary

String	getRegexGroup(int number) Get a substring that matches a parenthesised group within the regular expression
SequenceIterator	getRegexGroupIterator() Get a sequence containing all the regex captured groups relating to the current matching item (except group 0, because we want to use indexing from 1).
boolean	isMatching() Determine whether the current item in the sequence is a matching item or a non-matching item

Method Detail

isMatching

boolean isMatching()

Determine whether the current item in the sequence is a matching item or a non-matching item

Returns:

true if the current item is a matching item

getRegexGroup

String getRegexGroup(int number)

Get a substring that matches a parenthesised group within the regular expression

Parameters:

number - the number of the group to be obtained

Returns:

the substring of the current item that matches the n'th parenthesized group within the regular expression

getRegexGroupIterator

SequenceIterator getRegexGroupIterator()

Get a sequence containing all the regex captured groups relating to the current matching item (except group 0, because we want to use indexing from 1). This is used by the saxon:analyze-string() higher-order extension function.
