xpath nodejs

To use XPath with Node.js, you can follow these steps:

1. Install the xpath package using npm:

npm install xpath

1. Require the xpath package in your Node.js file:

var xpath = require('xpath');
var dom = require('xmldom').DOMParser;

1. Parse the XML document using the xmldom package:

var xml = "<bookstore><book><title>Harry Potter</title></book></bookstore>";
var doc = new dom().parseFromString(xml);

1. Use the xpath package to evaluate expressions on the XML document:

var nodes = xpath.select("//book/title", doc);
nodes.forEach(function(node) {
  console.log(node.toString());
});
