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')`.
