JRegularExpression
public JRegularExpression(CharSequence regex, boolean isXPath, CharSequence flags) throws XPathException Create (compile) a regular expression- Parameters:
regex
- the source text of the regular expression, in XML Schema or XPath syntaxisXPath
- set to true if this is an XPath regular expression, false if it is XML Schemaflags
- the flags argument as supplied to functions such as fn:matches(), in string form- Throws:
XPathException
- if the syntax of the regular expression or flags is incorrect

Method Details
-
analyze
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.- Specified by:
analyze
in interfaceRegularExpression
-
containsMatch
Determine whether the regular expression contains a match for a given string- Specified by:
containsMatch
in interfaceRegularExpression
- Parameters:
input
- the string to match- Returns:
- true if the string matches, false otherwise
-
matches
Determine whether the regular expression match a given string in its entirety- Specified by:
matches
in interfaceRegularExpression
- Parameters:
input
- the string to match- Returns:
- true if the string matches, false otherwise
-
replace
Replace all substrings of a supplied input string that match the regular expression with a replacement string.- Specified by:
replace
in interfaceRegularExpression
- Parameters:
input
- the input string on which replacements are to be performedreplacement
- 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
-
tokenize
Use this regular expression to tokenize an input string.- Specified by:
tokenize
in interfaceRegularExpression
- Parameters:
input
- the string to be tokenized- Returns:
- a SequenceIterator containing the resulting tokens, as objects of type StringValue
-
setFlags
Set the Java flags from the supplied XPath flags.- Parameters:
inFlags
- the flags as a string, e.g. "im"- Returns:
- the flags as a bit-significant integer
- Throws:
DynamicError
- if the supplied value is invalid
