regex help with getting tag content in PHP

Question

so I have the code

function getTagContent($string, $tagname) {

    $pattern = \"/<$tagname.*?>(.*)<\\/$tagname>/\";
    preg_match($pattern, $string         


        

Answer 1

The 'title' tag is not on the same line as its closing tag, so your preg_match doesn't find it.

In Perl, you can add a /s switch to make it slurp the whole input as though on one line: I forget whether preg_match will let you do so or not.

But this is just one of the reasons why parsing XML and variants with regexp is a bad idea.
