About XML (Extensible Markup Language)

XML is a markup language designed to store and transport data. It focuses on what data is, using descriptive tags to define both the structure and content. XML documents are human-readable and widely used for configuration files, web services, and data exchange.

XML uses a hierarchical structure with nested elements, attributes, and text content. Each XML document must have a root element, and elements can contain other elements, creating a tree-like structure.

Example:
<?xml version="1.0" encoding="UTF-8"?>
<books>
  <book id="1">
    <title>XML Guide</title>
    <author>John Doe</author>
    <price>29.99</price>
  </book>
  <book id="2">
    <title>Data Formats</title>
    <author>Jane Smith</author>
    <price>39.99</price>
  </book>
</books>

About JSON (JavaScript Object Notation)

JSON is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is language-independent and has become the de facto standard for web APIs and data exchange.

JSON uses key-value pairs, arrays, and nested objects to represent data. It is more concise than XML and is the preferred format for APIs, web applications, and data processing tasks.

Example (from above XML):
{
  "books": {
    "book": [
      {
        "@attributes": {"id": "1"},
        "title": "XML Guide",
        "author": "John Doe",
        "price": "29.99"
      },
      {
        "@attributes": {"id": "2"},
        "title": "Data Formats",
        "author": "Jane Smith",
        "price": "39.99"
      }
    ]
  }
}

XML to JSON Conversion Rules

Element Tags:

XML element tags become JSON object keys with their content as values.

Attributes:

XML attributes are stored under @attributes key as a nested object.

Multiple Elements:

When multiple elements have the same tag, they are converted to a JSON array.

Text Content:

Pure text content is stored as string values, mixed content uses #text key.

Empty Elements:

Empty XML elements become null or empty objects in JSON.
