Interface RegularExpression

  • All Known Implementing Classes:
    ARegularExpression, JavaRegularExpression
    public interface RegularExpression
    This interface represents a compiled regular expression. There are different implementations for different regex engines

    • Method Detail

      • matches

        boolean matches​(UnicodeString input)
        Determine whether the regular expression matches a given string in its entirety
        Parameters:
        input - the string to match
        Returns:
        true if the string matches, false otherwise

      • containsMatch

        boolean containsMatch​(UnicodeString 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

        AtomicIterator tokenize​(UnicodeString 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​(UnicodeString 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

        UnicodeString replace​(UnicodeString input,
                      UnicodeString 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

      • replaceWith

        UnicodeString replaceWith​(UnicodeString input,
                          java.util.function.Function<UnicodeString,​UnicodeString> 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 - a function that is called once for each matching substring, and that returns a replacement for that substring
        Returns:
        the result of performing the replacement
        Throws:
        XPathException - if the replacement string is invalid

      • getFlags

        java.lang.String getFlags()
        Get the flags used at the time the regular expression was compiled.
        Returns:
        a string containing the flags

      • isPlatformNative

        boolean isPlatformNative()
        Ask whether the regular expression is using platform-native syntax (Java or .NET), or XPath syntax
        Returns:
        true if using platform-native syntax
