如何将反应组件转换为 html 字符串？

Question

I have found similar to my issue here .

But I have a little bit different scenario. I have string of html rather than just string. So, I wanted to do:

Let's suppose MyComponent is just returning h3 element for now:

const MyComponent = ({children}) => (<h3>{children}</h3>)

var parts = "<h1>I</h1><p>am a cow;</p>cows say moo. MOOOOO."
    .split(/(\bmoo+\b)/gi);
for (var i = 1; i < parts.length; i += 2) {
  parts[i] = <MyComponent key={i}>{parts[i]}</MyComponent>;
}
// But I need html to be rendered
return <div dangerouslySetInnerHTML={{ __html: parts }} />

This will be rendered in the browser like this:

I
am a cow;
cows say ,[object Object],. ,[object Object],.

What I can think here to resolve the issue is converting component with string of html first.

parts[i] = convertToStringOfHtml(<MyComponent key={i}>{parts[i]}</MyComponent>);

But I don't have idea how to convert component to string of html.

You can do with react-dom

import { renderToString } from 'react-dom/server'
//
//
parts[i] = renderToString(<MyComponent key={i}>{parts[i]}</MyComponent>)
