Hi to All,

I am reading regx from a txt file in which data is written in XML format.
Now the problem is when is get the regx after reading and parsing the file .
The reg exp does not work fine. I mean matcher,matches() return false for any kind of input string.


Can anyone help in this??

Read this.

That sort of comment is an effective way of annoying everybody else and dissuading them from answering.

Just shows you . . . these errors appear mysteriously when you least expect them and where you least expect them.
 
It is sorta covered in the JavaRanch Style Guide.
