Getting content using wikipedia API

How 开发者_开发问答can I get the entire first section/paragraph of a Wikipedia article including the first image with a single request?

What I've tried so far (the following url) returns only a snippet:

http://en.wikipedia.org/w/api.php?format=xml&action=query&list=search&srsearch=camera&srlimit=1

If you're wanting the wikitext, use prop=revisions with rvsection=0. If you're wanting HTML, you can add rvparse=1 to that query or you can use action=parse.

How can I get the entire first section/paragraph of a Wikipedia article including the first image with a single request?

It's not possible to do that in one request.
