🛠 Installation

Install using NPM or Yarn:

npm i --save js-parse-xml

OR

yarn add js-parse-xml

🌟 Getting Started

ESM Imports

import { Parser, parseString, parseStringSync, parseFile, parseFileSync } from "js-parse-xml";

CommonJS Imports

const { Parser, parseString, parseStringSync, parseFile, parseFileSync } = require("js-parse-xml");

📸 Example

Synchronous Parsing

let json = parseStringSync("<xml>Example!</xml>");
// do whatever with the json here

let json = parseFileSync("file.xml");
// do whatever with the json here

Asynchronous Parsing

async function parse(string) {
  let json = await parseString(string);
  // do whatever with the json here
}
parse("<xml>Testing</xml>");

async function parse(file) {
  let json = await parseFile(file, { stream: true });
  // do something with the json
}
parse("large_file.xml");

Using the Parser Class

// strict:false will continue parsing if it finds error
let parser = new Parser({ strict: false });

// create stream and feed each chunk to the parser
let stream = fs.createReadStream("filename.xml", "utf-8");

stream.on("data", parser.feed);

stream.on("end", () => {
  let json = parser.finish();
  // do whatever with the json
});

🌍 Supported Environments

• Node.js
• Browsers (with bundlers like Webpack or Rollup)
