Try this:
function readTag($filenane, $tagtype, $degub = false)
// I prefer boolean for debug :)
{
$filedata = file_get_contents($filename);
$tagtype = preg_quote($tagtype);
$tagRegExp = "/<battag=$tagtype\s*>((?:.|\s)*?)</battag\s*>/";
preg_replace_callback($tagRegExp, 'replaceFunc', $filedata);
}
function replaceFunc(match)
{
// match[0] --- the whole tag from <x> to </x>
// match[1] --- the contents of the tag
// I am my self !!! in the example
return WHATEVER_YOU_WANT_TO_REPLACE_THE_TAG;
}
I didnt make sure this script will work 100%; but it should.
