How to render svg file in react?-CodePudding

I want to upload a svg file and show preview in react, but I don't know how to convert a svg file into react component. I try to use DOMParser to parse svg-xml string to Dodument Object, but it is not working.

import { useState } from 'react';
import { Upload, Button, Card } from 'antd';
import { UploadChangeParam } from 'antd/lib/upload/interface';
import 'antd/dist/antd.css';

function App() {
  const [svgs, setSvgs] = useState<Document[]>([]);

  const handleChange = async ({ file }: UploadChangeParam) => {
    console.log(file);
    let domparser = new DOMParser();
    const svg = (await file.originFileObj?.text()) ?? '';
    const ele = domparser.parseFromString(svg, 'image/svg xml');
    setSvgs([...svgs, ele]);
  };

  return (
    <div style={{ margin: 50 }}>
      <Upload name="file" showUploadList={false} onChange={handleChange}>
        <Button>Upload</Button>
      </Upload>
      {/* preview list */}
      <Card style={{ marginTop: 20 }}>
        {svgs.map((SVGComponent) => {
          return <SVGComponent />;
        })}
      </Card>
    </div>
  );
}

export default App;
