Let's make a loop over `<li>`:
```js
for (let li of document.querySelectorAll('li')) {
...
}
```
In the loop we need to get the text inside every `li`. We can read it directly from the first child node, that is the text node:
```js
for (let li of document.querySelectorAll('li')) {
let title = li.firstChild.data;
// title is the text in <li> before any other nodes
}
```
Then we can get the number of descendants `li.getElementsByTagName('li')`.
