Hi, I would like to know the regex options equalent to the following .Net Reqular Expressions Options: ** *Multiline* ** Specifies multiline mode. Changes the meaning of *^* and *$* so that they match at the beginning and end, respectively, of any line, not just the beginning and end of the whole string. *ExplicitCapture* ** Specifies that the only valid captures are explicitly named or numbered groups of the form (?<*name*>…). This allows parentheses to act as noncapturing groups without the syntactic clumsiness of (?:…). ** *Singleline* ** Specifies single-line mode. Changes the meaning of the period character (.) so that it matches every character (instead of every character except *\n*). *IgnorePatternWhitespace* ** Specifies that unescaped white space is excluded from the pattern and enables comments following a number sign (#). (For a list of escaped white-space characters, see Character Escapesms-help://MS.MSDNQTR.2005JUL.1033/cpgenref/html/cpconcharacterescapes.htm.) Note that white space is never eliminated from within a character class. Thanks in Advance. Regards Kiran
