使用jquery / javascript提取第一个div元素的类名

Question

i have a couple of div elements as string, is there any way to extract the name of the class of the first div element ? I tried (#element).attr('class'). it does not yield results,may be because it is a string.here is the sample div. PLease note that , it has just div tags and the type of the whole structure is string

<div class="some class" ><div class="inner div"></div></div>

I want "some class" value. The typeof this whole thing is a string. Thanks in advance
