Feature Comparison: fast-xml-parser vs xmlbuilder vs xml2js vs xmlbuilder2 vs libxmljs

Performance

  • fast-xml-parser:

    fast-xml-parser is optimized for speed and can parse large XML files quickly, making it ideal for performance-sensitive applications.

  • xmlbuilder:

    xmlbuilder is efficient for generating XML but performance can vary based on the complexity of the XML being built.

  • xml2js:

    xml2js is generally slower than fast-xml-parser, as it focuses on ease of use rather than raw performance, making it suitable for smaller XML files.

  • xmlbuilder2:

    xmlbuilder2 improves upon its predecessor with better performance metrics, especially in async contexts.

  • libxmljs:

    libxmljs offers good performance but may be slower than fast-xml-parser due to its comprehensive feature set and additional processing capabilities.

Ease of Use

  • fast-xml-parser:

    fast-xml-parser provides a simple API that is easy to understand, making it accessible for developers who need quick XML parsing without a steep learning curve.

  • xmlbuilder:

    xmlbuilder has a fluent API that simplifies the process of creating XML documents, making it intuitive for developers to use.

  • xml2js:

    xml2js is known for its straightforward API, allowing developers to easily convert XML to JavaScript objects and vice versa, making it very user-friendly.

  • xmlbuilder2:

    xmlbuilder2 continues the trend of user-friendliness with an even more modern API that supports async operations, making it easier to integrate into contemporary JavaScript applications.

  • libxmljs:

    libxmljs has a more complex API due to its extensive features, which may require more time to learn and master, especially for beginners.

Feature Set

  • fast-xml-parser:

    fast-xml-parser focuses on parsing and does not include features like XPath or XSLT, making it lightweight but limited in functionality.

  • xmlbuilder:

    xmlbuilder is specifically designed for building XML documents and does not include parsing capabilities, focusing solely on document creation.

  • xml2js:

    xml2js provides basic parsing and building capabilities but lacks advanced features like XPath or validation, focusing instead on simplicity.

  • xmlbuilder2:

    xmlbuilder2 enhances the building experience with a modern API and better support for promises, but it still does not include parsing capabilities.

  • libxmljs:

    libxmljs is feature-rich, supporting XPath queries, XSLT transformations, and schema validation, making it suitable for complex XML processing tasks.

Community and Support

  • fast-xml-parser:

    fast-xml-parser has a growing community and decent documentation, but it may not have as extensive support as some of the more established libraries.

  • xmlbuilder:

    xmlbuilder has a solid user base and sufficient documentation, making it easy to find examples and support.

  • xml2js:

    xml2js is widely used and well-documented, providing ample resources and community support for developers.

  • xmlbuilder2:

    xmlbuilder2 benefits from the popularity of its predecessor and has a supportive community, along with updated documentation for modern usage.

  • libxmljs:

    libxmljs has a strong community and good documentation, making it easier to find help and resources for complex tasks.

Compatibility

  • fast-xml-parser:

    fast-xml-parser is compatible with both Node.js and browser environments, making it versatile for different projects.

  • xmlbuilder:

    xmlbuilder is compatible with Node.js and can be used in browser environments with some adjustments, making it versatile for XML creation.

  • xml2js:

    xml2js works well in both Node.js and browser contexts, providing flexibility for developers working in various environments.

  • xmlbuilder2:

    xmlbuilder2 is designed for modern JavaScript and works seamlessly in Node.js and browser environments, supporting both ES5 and ES6.

  • libxmljs:

    libxmljs is primarily designed for Node.js and may not work in browser environments, limiting its use in client-side applications.

How to Choose: fast-xml-parser vs xmlbuilder vs xml2js vs xmlbuilder2 vs libxmljs
  • fast-xml-parser:

    Choose fast-xml-parser if you need a lightweight and high-performance XML parser that is easy to use and can handle large XML files efficiently. It is ideal for applications where speed is crucial and where you can work with a simpler API.

  • xmlbuilder:

    Use xmlbuilder if you need to create XML documents programmatically. It provides a fluent API for building XML structures and is great for generating XML from scratch, especially when you need to ensure the output is well-formed.

  • xml2js:

    Select xml2js if you prefer a simple and straightforward way to convert XML to JavaScript objects and vice versa. It is user-friendly and works well for basic XML parsing needs without overwhelming complexity.

  • xmlbuilder2:

    Choose xmlbuilder2 for a more modern and flexible approach to building XML documents. It offers an improved API and better support for promises and async/await, making it suitable for contemporary JavaScript applications.

  • libxmljs:

    Opt for libxmljs if you require a comprehensive XML library that supports XPath, XSLT, and schema validation. It is suitable for complex XML processing tasks where you need robust features and performance, but it may have a steeper learning curve.

NPM total downloads

Validate XML, Parse XML to JS Object, or Build XML from JS Object without C/C++ based libraries and no callback.

FXP logo
  • Validate XML data syntactically. Use detailed-xml-validator to verify business rules.
  • Parse XML to JS Objectand vice versa
  • Common JS, ESM, and browser compatible
  • Faster than any other pure JS implementation.

It can handle big files (tested up to 100mb). XML Entities, HTML entities, and DOCTYPE entites are supported. Unpaired tags (Eg <br> in HTML), stop nodes (Eg <script> in HTML) are supported. It can also preserve Order of tags in JS object
