Topic awaiting preservation: Perl REGEX Hex character

I would like to search for a hex charater "A0" and remove it from my text file...is this possible with Perl. I would like to learn how to do it so please post examples or URLs that show how to perform this substitution.

sure you can search for hex like so

$test =~ s/\xA0//g;


a breakdown would be

s <-- substitute
/ <-- delimeter
\ <-- unescape
x <-- this is a hex value
/ <-- delimeter
/ <-- delimeter
g <-- look globally


or the decimal way (I think this is it)

$test =~ s/\160//g





.:[ Never resist a perfect moment ]:.

great thanks that helps...epanding on that though what if you need to search for hex codes '0D 0A' together? Right now I am removing these as \n at the beginning of my script then adding them in later in the script to fix formatting. If I could remove these without having to strip all the \n at the beginning of the script I'd be a lot happier.

I assume that this relates to your other thread about finding tags in an HTML file.

The best way to do this is

if  (not open(INPUT, "< file.html"))

     {   print ("Can't open 'file.html'\n"); }

   else

     {

       @input = <INPUT>;       # This line reads the entire file into @input

        close(INPUT);

       chomp(@input);            # This line removes the \n's from each line



       foreach $line (@input)

         {

           # process each line

         }

     }
