How to use the STATE function from sax

sax.STATE is a constant that represents the state of a SAX parser.

How does sax.STATE work?

sax.STATE is a constant object in the sax.js library that defines various parsing states and their corresponding behaviors in the context of parsing an XML or HTML document. It is used to manage the parser's state and ensure that each piece of the document is handled appropriately during parsing. The sax.STATE object includes properties such as BEGIN, CLOSED, and CDATA, each with its own set of parsing rules and behavior.

const sax = require("sax");
const parser = sax.parser(true);

parser.onopentag = function (node) {
  if (node.name === "book") {
    console.log(sax.STATE.tag); // output: 1
  }
};

parser.write(" ");

In the above example, sax.STATE.tag is accessed inside the onopentag event handler of the sax parser. It represents the state of the parser when it encounters an opening tag. When the parser encounters the opening tag, it logs the value of sax.STATE.tag which is equal to 1.
