``javascript
const htmlparser2 = require("htmlparser2");
const parser = new htmlparser2.Parser({
onopentag(name, attributes) {
/*
* This fires when a new tag is opened.
*
* If you don't need an aggregated attributes object,
* have a look at the onopentagname and onattribute events.
*/
if (name === "script" && attributes.type === "text/javascript") {
console.log("JS! Hooray!");
}
},
ontext(text) {
/*
* Fires whenever a section of text was processed.
*
* Note that this can fire at any point within text and you might
* have to stich together multiple pieces.
*/
console.log("-->", text);
},
onclosetag(tagname) {
/*
* Fires when a tag is closed.
*
* You can rely on this event only firing when you have received an
* equivalent opening tag before. Closing tags without corresponding
* opening tags will be ignored.
*/
if (tagname === "script") {
console.log("That's it?!");
}
