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.

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&quot

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
# [red]s/XXXX/YYYY/[/red] says replace 'XXXX' with 'YYYY'
# and [red]gis[/red] says do it [red]G[/red]lobally,
# [red]I[/red]gnore case,
# and treat the entire thing as one [red]S[/red]tring.

open(OPF,">SomeFile&quot

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. [sig]<p> <br><a href=mailto: > </a><br><a href= > </a><br> keep the rudder amid ship and beware the odd typo[/sig]
