Introduction to js2xmlparser

Welcome to our comprehensive guide on js2xmlparser, the premier library for converting JavaScript objects to XML with ease and efficiency. Whether you’re dealing with simple or complex XML structures, js2xmlparser simplifies the process and allows for seamless integration of XML data in your applications. Below, we explore the extensive API offerings of js2xmlparser along with numerous practical code snippets to get you started quickly.

Getting Started with js2xmlparser

Install the library via npm:

npm install js2xmlparser

Here’s a simple example of how to use js2xmlparser:

  const js2xmlparser = require("js2xmlparser");

  let obj = {
    "firstName": "John",
    "lastName": "Doe",
    "age": 29
  };

  let xml = js2xmlparser.parse("person", obj);
  console.log(xml);

Array Handling

js2xmlparser handles arrays intelligently, converting them into the appropriate XML format:

  let obj = {
    "people": [
      {
        "firstName": "John",
        "lastName": "Doe",
        "age": 29
      },
      {
        "firstName": "Anna",
        "lastName": "Smith",
        "age": 24
      }
    ]
  };

  let xml = js2xmlparser.parse("root", obj);
  console.log(xml);

Attribute Support

Add attributes to your XML nodes effortlessly:

  let obj = {
    "@": {
      "type": "example",
      "version": "1.0"
    },
    "firstName": "John",
    "lastName": "Doe",
    "age": 29
  };

  let xml = js2xmlparser.parse("person", obj);
  console.log(xml);

Value Wrapping

Wrap values in XML tags effectively:

  let obj = {
    "person": {
      "value": {
        "firstName": "John",
        "lastName": "Doe",
        "age": 29
      },
      "type": "example"
    }
  };

  let xml = js2xmlparser.parse("root", obj);
  console.log(xml);

Complex Nested Objects

Create XML from deeply nested objects:

  let obj = {
    "order": {
      "orderId": "12345",
      "customer": {
        "firstName": "John",
        "lastName": "Doe",
        "address": {
          "street": "123 Main St",
          "city": "Anytown",
          "state": "NY"
        }
      }
    }
  };

  let xml = js2xmlparser.parse("orderInfo", obj);
  console.log(xml);

App Example with js2xmlparser

Let’s create a Node.js app that uses js2xmlparser to manage user data and convert it to XML:

  const js2xmlparser = require("js2xmlparser");
  const express = require("express");
  const app = express();

  app.use(express.json());

  app.post("/convert", (req, res) => {
    let xml = js2xmlparser.parse("user", req.body);
    res.header("Content-Type", "application/xml");
    res.send(xml);
  });

  app.listen(3000, () => {
    console.log("Server is running on port 3000");
  });

This app listens for POST requests on the /convert endpoint, converts the JSON payload to XML, and returns the XML response.

With js2xmlparser, XML manipulation in JavaScript has never been easier. From basic conversion to handling complex nested structures and attributes, this library provides all the tools you need.
