Answer 1

+1 A:

Edited to allow multiple includes and file checking.

$content = '<b>Hello world,</b>
<include file="dynamiccontent.php" />
<img src="world.png" />
a lot of <i>stuff</i>';

preg_match_all('!<include file="([^"]+)" />!is', $content, $matches); 
if(count($matches) > 0)
{
    $replaces = array();
    foreach ($matches[1] as $file)
    {
        $tag = '<include file="'.$file.'" />';
        if(is_file($file) === true)
        {   
            ob_start();
            require $file;
            $replaces[$tag] = ob_get_clean();
        } 
        else
        { 
            $replaces[$tag] = '{Include "'.$file.'" Not Found!}';
        }
    } 
    if(count($replaces) > 0)
    {
        $content = str_replace(array_keys($replaces), array_values($replaces), $content);
    }
}

echo $content;

+1 A:

So you wanna know what the value of the attribute file of the element include? Try:

$sgml = <<<HTML
<b>Hello world,</b>
<include file="dynamiccontent.php" />
<img src="world.png" />
a lot of <i>stuff</i>
HTML;

preg_match('#<include file="([^"]+)"#',$sgml,$matches);

print_r($matches[1]); // prints dynamiccontent.php

If not, please Elaborate.

Yeah, this is good but in this case I can only extract the file name, without loading the other content, if you see the string contains some html tag and text..

mh.. I can replace the include with a simple replacement.. :s

/(?<=<include file=").+(?=")/

matches "dynamiccontent.php" from your input string
