    <div class = "lvltwo"> Hello
        <span>World</span>
    </div>
</div>

I do this:$res = $xpath->query(//div[@class='lvlone']/div[@class='lvltwo']);

I get Hello World including the string in <span> tag but i down want it!
I only want the Hello.

As TheZ points out, you can use the text() function from XPath:

$nodes = $xpath->query( '//div[@class="lvltwo"]/text()');
echo $nodes->item(0)->nodeValue; // Prints 'Hello'
