## net.sf.saxon.regex
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

Fields inherited from interface net.sf.saxon.om.SequenceIterator
`GROUNDED, LAST_POSITION_FINDER, LOOKAHEAD`

Method Summary
`java.lang.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

Methods inherited from interface net.sf.saxon.om.SequenceIterator
`close, current, getAnother, getProperties, next, position`

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

    java.lang.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.
