Homework? Or some fundamental religious rule which forbids you to handle HTML other than with a regex? CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply]

<flame suit on> `$html =~ /(<body[^>]+>)/s;` [download] `$html =~ /(<body[^>]>)/s;` [download] that should get you the opening tag. Update: Changed + to as pointed out by kwaping	[reply] [d/l] [select]

That'll fail for `<body onload="if (a > b) { ... }">`. It can also fail if `<body>` is found in comments.	[reply] [d/l] [select]

See Re: Regular Expression (the bottom regexp) - although to be fair, it should probably check for single quotes, too...	[reply]

And how do you find the closing tag? CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply]

Even though I believe this is a rhetorical question... `m!</body>!` [download] Yes.. with multiple closing body tags, it will be icky - yes, enclosed in comments it will be double super secret fudgy icky. But the OP wants a regexp to find the tag (and actually didn't even ask about the closing tag!), so like Burger King, "Have it Your Way".	[reply] [d/l]

The OP didn't ask for that. He asked to match the opening tag, no matter what it had for attributes.	[reply]
