regular expression, white spaces
I'm trying to remove the white spaces in front and after a variable. The variable comes from a file which needs to be read. The following code seems to work at first:
return "" if !defined $str;
However, when I try this code, it doesn't remove anything. I tried to open the input file in a text editor and saw white spaces in front and after the string. When I tried in a dos box "type input.txt" I noticed all the white spaces got replaced by "á" signs.
I'm guessing I'll need to use another expression, the problem is I don't know what to match for. How can I discover that hidden character that seems like a white space, but isn't one after all?
