regex : best way to get only the <body>...</body>

kevinpham · Jan 18, 2002

Hi,
What is the bestway to extract only the <body>....</body> of an HTML file, and convert all links and graphics to their predefined URL.
For example, if I have
<html><head></head><body>
junk <a href="/local/files/.html"><img src="/local/images/.gif"></a>

junk <a href="

http://www.me.com/"><img

src="

http://me.com/images.gif"></a>

</body></html>
-----------------------
what i want is to get the part from <body>(this part)</body>
and convert all links and images that do not start with http:// to

http://,

if we know /local/files will be

http://www.me.com/local/files

It is not that hard, but I have some problems w/ it. When I convert all local files to URL, it is messup.

Really appreciate for all you guys help.

You can catch the <body></body> chunk like this,

Code:

$html_text =~ /<body>.*?</body>/is;
$body = $&;

Then,

Code:

$body =~ s/<a href=&quot;(.*?)&quot;/fix_url($1)/egis;

sub fix_url
{
my $url = shift;
unless ($url =~ /^http:\/\//)  
  { $url = '<a href=[URL unfurl="true"]http://'.$url.'</a>;[/URL] }
return($url)
}

The 'e' switch on the regex triggers the evaluation of the right side of the regex for the replacement. So, the contents of the anchor tag are passed to sub fix_url which tweaks the url if needed and passes it back for the replacement.

I have not run this so it might need a syntax tweak, but, hopefully it illustrates one approach that might do what you want.

'hope this helps
