rapid-xml-to-json

rapid-xml-to-json is a fast, lightweight XML parser designed for simple hierarchical XML data.

Features

This library is built for performance and simplicity. Below is a summary of what it can and cannot do:

✅ Features

• Parses well-formed XML into a nested JavaScript object.
• Handles basic XML structures with child elements.
• Sets attributes on elements ($attrs)
• Supports CDATA sections.
• Skips comments, processing instructions (<?...?>), and <!DOCTYPE> declarations.

❌ Limitations

• Does not handle mixed content (text between and around child elements). (To be implemented)
• Does not validate XML (assumes input is well-formed).

Installation

You can install the library via npm:

npm install rapid-xml-to-json

Usage

Here’s how you can use rapid-xml-to-json:

import { xlmToJson } from 'rapid-xml-to-json';

const xml = `
<root>
  <item>
    <![CDATA[Some content here]]>
  </item>
  <item>
    <subitem>Another piece of content</subitem>
  </item>
</root>
`;

const parsed = xmlToJson(xml);

console.log(parsed);
// Output:
// {
//   root: {
//     item: [
//       "Some content here",
//       { subitem: "Another piece of content" }
//     ]
//   }
// }

Performance

rapid-xml-to-json is optimized for speed and low memory usage, skipping some XML features to avoid overhead.
