尝试comp.lang.perl。


正则表达式是Perl的一个整体部分。在C中你必须自己获得

库，语法不同。

Try comp.lang.perl.

Regular expressions are an integeral part of Perl. In C you have to get the
library yourself, and syntax differs.

尝试comp.lang.perl。

Try comp.lang.perl.

实际上comp.unix.programmer可能更合适。

Actually comp.unix.programmer might be more appropriate.

你还没有定义字母。你需要匹配

德国Eszett和（更常见的）Sanskrit ghnya吗？

You haven''t defined "alphabets". Do you need to match the
German Eszett along with the (rather more common) Sanskrit ghnya ?
