If I have some HTML in the response that looks like:

```
<body>
    Body text
    <div>
        Div text
    </div>
</body>

```

If I do `response.xpath('//body/text()').extract()` I will only get `[Body text]`

I want to get **everything** inside `<body>` including the tags i.e. this whole thing:

```
Body text
<div>
    Div text
</div>

```

How can I accomplish that?

Thank you.
