Return first line of parsing

[Haze Noc]

mysite.each {|line|
if line =~ /<p><a href="(.+)"><b>(.+)<\/b>/
puts "#{$2} found at: #{$1}"
end
}

Ok guys, Lets say the website has 50+ lines.. and i only want to return
the first one, any ideas?

Careful,
What if the site's white space has been stripped? (no CR or LF at all)
or if the html/xhtml is screwy? (old html without closed elements,
or just poorly formed or badly nested)

The first line of any file doesn't depend on the html in it. His code
should return the first line of any file -- html or no.

If you want to use essentially the same block as above, but just take
the first matching line:

mysite.each {|line|
if line =~ /<p><a href="(.+)"><b>(.+)<\/b>/
puts "#{$2} found at: #{$1}"
break
end
}

Tim's solution would give you the first line of the actual html file
and, as John mentions, that could be the entire web page if there are
no CR/LF characters in the file.
