javascript - How to parse html to React component?

This is my senario :
1. Application request CMS(Content management system) for page contents.
2. CMS return "<div>Hi,<SpecialButton color="red">My Button</SpecialButton></div>"
3. Application consume the content, render corresponding component with data provided in attribute.

I can't figure out how to do step 3 in React way, any advice is appreciated.

Thanks @Glenn Reyes, here's a Sandbox to show the problem.

import React from 'react';
import { render } from 'react-dom';

const SpecialButton = ({ children, color }) => (
  <button style={{color}}>{children}</button>
);

const htmlFromCMS = `
<div>Hi, 
  <SpecialButton color="red">My Button</SpecialButton>
</div>`;

const App = () => (
  <div dangerouslySetInnerHTML={{__html: htmlFromCMS}}>
  </div>
);

// expect to be same as
// const App = () => (
//   <div>Hi, 
//     <SpecialButton color="red">My Button</SpecialButton>
//   </div>
// );

render(<App />, document.getElementById('root'));

Here is a live demo made by Vuejs. String "<div v-demo-widget></div>" could be treat as Vuejs directive and rendered. Source Code.

You probably want to look deeper into dangerouslySetInnerHTML. Here is an example how to render HTML from a string in a React component:

import React from 'react';
import { render } from 'react-dom';

const htmlString = '<h1>Hello World! ??</h1>';

const App = () => (
  <div dangerouslySetInnerHTML={{ __html: htmlString }} />
);

render(<App />, document.getElementById('root'));

Full example here: https://codesandbox.io/s/xv40xXQzE

Read more about dangerouslySetInnerHTML in the React docs here: https://facebook.github.io/react/docs/dom-elements.html#dangerouslysetinnerhtml
