Guys help me with Regx

(OP)
Guys !

      How to find a particular text in a file and replace it with another one.

I have a html file in which i have to replace a particular text XXXX with YYYY.


Html file:
<html>
<head>
<title>test</title>
</head>
<body>
XXXX
</body>
</html>


Whether i need to read whole file and when that particular text apperars i have to replace with the new one and then rewrite the whole file with the replaced one.

Is there any shorter way other than this.

Regx Gurus help me.



RE: Guys help me with Regx

Good morning thendal,

I don't know of an easy way to avoid reading the entire file and going from there.  Unless the file is LARGE, I don't see a problem with reading the entire thing.  That said (written),.......

open(IPF,"<SomeFile") or die "Failed to open SomeFile for reading, $!\n";
while (<IPF>) { $buffer .= $_; }
close IPF;

# now $buffer contains the entire file.
# so, for the regex part of the question.....

$buffer =~ s/XXXX/YYYY/gis;
# where =~ triggers the pattern match
#          s/XXXX/YYYY/ says replace 'XXXX' with 'YYYY'
#         and gis says do it Globally,
#                Ignore case,
#                and treat the entire thing as one String.

open(OPF,">SomeFile") or die "Failed to open SomeFIle to write, $!\n";
print OPF "$buffer";
close OPF;


'hope this helps....scream if you need a little more specific help on the regex stuff.




keep the rudder amid ship and beware the odd typo
