throws XPathException
evaluateItem in interface ExpressionevaluateItem in class ComputedExpressionc - The dynamic evaluation context
XPathException - on an error
public static RegularExpression tryToCompile(Expression[] args,

throws XPathException
args - the supplied arguments to the function, as an arraypatternArg - the position of the argument containing the regular expressionflagsArg - the position of the argument containing the flags
XPathException - if any failure occurs, in particular, if the regular
expression is invalid
