Re^2: Regular Expression

What will happen when a <body> tag is included in comments? Your regex will break. I'm almost sure that the one who gave the instruction to find the <body> of the HTML code with a simple regex did not think about this.

Interesting observation - do you often see body tags enclosed in comments? You are assuming the poster doesn't want body tags enclosed in comments. ;) In any case, I think this pattern is better (added ^): `my $body = $the_html_string; $body =~ s/^.?(<body.?>)/$1/sgi;` [download]	[reply] [d/l]

One can put anything in comments. Sometimes I have different alternative opening tags and the one I don't need I simply comment out. A naive regex search for the opening `<body>` tag would perhaps find the wrong (=commented out) tag.

You will still end up with a trailing `</html>`-tag and any comments outside of the closing `</body>` tag. CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply] [d/l] [select]
