public class Tokenize extends SystemFunction
This class implements the tokenize() function for regular expression matching. This returns a sequence of strings representing the unmatched substrings: the separators which match the regular expression are not returned.- See Also:

Method Detail

simplify
public Expression simplify(StaticContext env) throws XPathException
Simplify and validate. This is a pure function so it can be simplified in advance if the arguments are known- Specified by:
simplify
in interfaceExpression
- Overrides:
simplify
in classFunctionCall
- Parameters:
env
- the static context- Returns:
- the simplified expression
- Throws:
XPathException
- if an error is discovered during expression rewriting
-
iterate
public SequenceIterator iterate(XPathContext c) throws XPathException
Iterate over the results of the function- Specified by:
iterate
in interfaceExpression
- Overrides:
iterate
in classComputedExpression
- Parameters:
c
- supplies the context for evaluation- Returns:
- a SequenceIterator that can be used to iterate over the result of the expression
- Throws:
XPathException
- if any dynamic error occurs evaluating the expression
-
main
public static void main(java.lang.String[] args) throws java.lang.Exception
Simple command-line interface for testing.- Parameters:
args
- (1) the string to be tokenized (2) the regular expression- Throws:
java.lang.Exception
