parser.valid accepts malformed input

[BadIdeaException]

It seems that parser.valid accepts even the most ludicrously malformed input strings as valid HTML:

const { valid } = require('node-html-parser');

var valid = require("node-html-parser").valid;

valid('<p abc</p'); // false
valid('<div<p abc</p></span>'); // false
valid('<div><p abc</p></div>'); // true
valid('<div<p abc</a></div>'); // true
valid('@#><p'); // true
valid('<<>'); // true

As far as I can see, none of the above should be true.
