You can manipulate the tree and serialize it back to HTML:

```ts
import {parse, stringify} from 'fast-xml-parser';

const root = parse('<!DOCTYPE html><html>hello</html>');

// change text node
root.children[1].children[0].name = 'hello, world!'

// <!DOCTYPE html><html>hello, world!</html>
console.log(stringify(root));
```

> TBD: DOM API to manipulate the tree in a handy way
