Which expert helps to write this regular

Who's going to help write this regular?

For example
I want to match the class or ID of an HTML tag. (ID with ID, no take Class)
It's best to match it with a DIV or a span or something.

Just didn't pay attention to write it into the source code, so that the format of confusion, see as follows:

function Gettaginfo (e) {
var str= ';
if (JQuery (e). attr (' id ')) {
str + = ' ID: ' +jquery (e). attr (' id ');
}else if (JQuery (e). attr (' class ')) {
str + = ' class: ' +jquery (e). attr (' class ');

}else{
str + = ' Neither set ID nor set class attribute ';
}
str + = ' \ntagname: ' +jquery (e). Get (0). TagName;
alert (str);
}

I did not see clearly, the original span or div is not necessarily, then change//* and then nodeName get the HTML tag name.

 
  $html = ";
$dom = new DOMDocument ();
@ $dom->loadhtml ($html);



{
    echo $node->getattribute ("id"); myID
Echo '
';
echo $node->getattribute ("class"); MyClass
Echo '
';
Echo $node->nodename; Div

?>
