I need a regex in php for matching contents between tags of an element, e.g. <body> and </body> with the perl compatible preg_match.
So far I tried with:
// $content is a string with html content
preg_match("/<body(.|\r\n)*\/body>/", $content, $matches);
print_r($matches);
…but the printout is an empty array.
You simply have to add the s modifier to have the dot match all characters, including new lines :
preg_match("/<body.*\/body>/s", $content, $matches);
as explained in the doc : http://nl2.php.net/manual/en/reference.pcre.pattern.modifiers.php
perl regexp match by default one line
you have to specify that you want to do a multi line search by adding a s or a m after the last /
ex:
$> perl -e 'print $1 if "bla\nbla\n<body>\nfirst line\n second line\n</body>\nbla" =~ /^.*<body>(.*)<\/body>.*$/s'
Almost a duplicated question :

It can help you even if it isn't exactly the same problem.
