Convert html snippet to a tree

Given a string that looks something like:

<div>
<div>
<a>
</div>
<div>
<p>
</div>
</div>

Convert it into a tree where you can search for any of those values based on their value input

				div
				/ \
			div   div
			/        \
			a          p
	```

No idea how to do this, any thought?
