RE: help on framing regular expression

[Srinivasan Krishnan <sr...@wipro.com>]

Hi,
Greetings

I am trying to use nested expression parsing.

When I follow the example given in
http://javaregex.com/cgi-bin/pat/tutorial6.asp used in ORO it gives

Sequence (?@...) not recognized exception..Any idea about the support in
ORO.


Here the text is

String text = "a=7; foo( x=2+4, bar(9) ); output(8);";

Regular expression is

String regexpForFontTag="foo(?@())";

Regards,
Srini sk

I think the pattern element

    (?@<>)

Should do what you want.  It was designed for matching nested
parenthesis. See http://javaregex.com/cgi-bin/pat/tutorial6.asp

Steve
