Introduction to j2x-parser

The j2x-parser library is a powerful and flexible tool that allows developers to convert JSON to XML with ease. This package is invaluable for web developers who need to work with data interchange formats that require both JSON and XML. Let’s delve into its capabilities and explore various API functions with relevant examples.

Initial Setup

  
    const J2xParser = require('j2x-parser');
    const parser = new J2xParser(options);
  

Converting JSON to XML

The primary function of the j2x-parser library is converting JSON objects to XML strings.

  
    const json = {
      root: {
        name: 'John',
        age: 30
      }
    };
    const xml = parser.parse(json);
    console.log(xml);
    // Outputs: <root><name>John</name><age>30</age></root>
  

Customizing Output

You can customize the XML output using various options provided by the library.

  
    const options = { 
      ignoreAttributes: false, 
      format: true 
    };
    const parser = new J2xParser(options);
    const xml = parser.parse(json);
    console.log(xml);
    /* Outputs:
    <root>
        <name>John</name>
        <age>30</age>
    </root>
    */
  

Handling Attributes

Parsing attributes within the JSON object is straightforward with j2x-parser.

  
    const json = {
      root: {
        '@_id': '1',
        name: 'John',
        age: 30
      }
    };
    const xml = parser.parse(json);
    console.log(xml);
    // Outputs: <root id="1"><name>John</name><age>30</age></root>
  

Parsing Arrays

Convert JSON arrays into corresponding XML elements using j2x-parser.

  
    const json = {
      root: {
        people: [
          { name: 'John', age: 30 },
          { name: 'Jane', age: 25 }
        ]
      }
    };
    const xml = parser.parse(json);
    console.log(xml);
    /* Outputs:
    <root>
        <people>
            <name>John</name>
            <age>30</age>
        </people>
        <people>
            <name>Jane</name>
            <age>25</age>
        </people>
    </root>
    */
  

Example Application

Below is a simple application demonstrating the integration of multiple j2x-parser functions.

  
    const J2xParser = require('j2x-parser');

    const options = { ignoreAttributes: false, format: true };
    const parser = new J2xParser(options);

    const json = {
        root: {
            '@_id': '1',
            name: 'John',
            age: 30,
            friends: [
                { name: 'Jane', age: 25 },
                { name: 'Doe', age: 30 }
            ]
        }
    };

    const xml = parser.parse(json);
    console.log(xml);
    /* Outputs:
    <root id="1">
        <name>John</name>
        <age>30</age>
        <friends>
            <name>Jane</name>
            <age>25</age>
        </friends>
        <friends>
            <name>Doe</name>
            <age>30</age>
        </friends>
    </root>
    */
  

With these examples, you can utilize the j2x-parser library to its fullest potential.
