To parse an HTML string with JavaScript, we create an element and put the HTML inside it.
For instance, we write
const el = document.createElement("html");
el.innerHTML =
"<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>";
const links = el.getElementsByTagName("a");
to call createElement
to create the html element.
Then we set its innerHTML
property to the HTML string we want to parse.
Next, we get the links from el
with getElementsByTagName
.
