Feature Comparison: dom-serializer vs htmlparser2 vs xmlbuilder vs cheerio

Parsing Capability

  • dom-serializer:

    Dom-serializer does not parse documents; instead, it focuses on converting DOM nodes back into string format. It is essential for outputting manipulated documents after changes have been made, ensuring that the final result is correctly formatted as HTML or XML.

  • htmlparser2:

    Htmlparser2 is designed for high-performance parsing of both HTML and XML. It can handle malformed HTML gracefully, making it a robust choice for applications that need to process a wide variety of document structures. It also supports streaming, which is beneficial for large documents.

  • xmlbuilder:

    Xmlbuilder specializes in creating XML documents from scratch. It allows developers to build XML structures in a straightforward manner, providing a clear API for defining elements, attributes, and nesting, which is essential for generating well-formed XML.

  • cheerio:

    Cheerio provides a fast and lightweight way to parse HTML documents. It uses a jQuery-like syntax, allowing for easy traversal and manipulation of the DOM. It is particularly effective for web scraping tasks, enabling developers to extract data from web pages effortlessly.

Performance

  • dom-serializer:

    Dom-serializer is lightweight and efficient, focusing solely on converting DOM nodes to strings. Its performance is generally high since it does not involve complex parsing operations.

  • htmlparser2:

    Htmlparser2 is known for its performance, especially with large documents. It can parse documents in a streaming fashion, allowing for efficient memory usage and faster processing of large or complex HTML and XML files.

  • xmlbuilder:

    Xmlbuilder is efficient for generating XML documents, but performance can vary based on the complexity of the structure being built. It is generally fast for standard use cases but may require optimization for very large XML outputs.

  • cheerio:

    Cheerio is optimized for speed, making it suitable for applications that require quick DOM manipulation. However, it operates in memory, which may not be ideal for very large documents compared to streaming parsers.

Ease of Use

  • dom-serializer:

    Dom-serializer has a straightforward API that is easy to understand, making it simple to convert DOM nodes to strings. Its focus on serialization means there is less complexity involved in its usage compared to full parsing libraries.

  • htmlparser2:

    Htmlparser2 has a steeper learning curve due to its more complex API and the need for understanding streaming parsing. However, it offers great flexibility and power once mastered, making it suitable for advanced use cases.

  • xmlbuilder:

    Xmlbuilder is designed to be intuitive, allowing developers to build XML structures in a clear and concise manner. Its API is straightforward, making it easy to create complex XML documents without deep XML knowledge.

  • cheerio:

    Cheerio's jQuery-like syntax makes it very approachable for developers familiar with jQuery. This ease of use allows for quick learning and efficient manipulation of HTML documents without needing extensive knowledge of the underlying parsing mechanics.

Use Cases

  • dom-serializer:

    Dom-serializer is primarily used in conjunction with other libraries to output manipulated DOM structures. It is essential in workflows where the final output needs to be serialized back into HTML or XML after processing.

  • htmlparser2:

    Htmlparser2 is suitable for applications that require robust parsing of both well-formed and malformed HTML/XML. It is often used in web crawlers, data extraction tools, and any application needing reliable document parsing.

  • xmlbuilder:

    Xmlbuilder is perfect for applications that need to generate XML documents dynamically. It is commonly used in APIs, configuration files, and any scenario where XML output is required.

  • cheerio:

    Cheerio is ideal for web scraping, data extraction, and any scenario where HTML manipulation is required. Its ability to traverse and modify the DOM makes it a go-to choice for developers working with web data.

Community and Support

  • dom-serializer:

    Dom-serializer is less commonly used as a standalone library, but it is well-documented and supported as part of the ecosystem of libraries that manipulate the DOM.

  • htmlparser2:

    Htmlparser2 has a solid community and is actively maintained. It is widely used in various projects, ensuring that developers can find support and resources easily.

  • xmlbuilder:

    Xmlbuilder is also well-supported, with a good number of users and documentation available. It is a reliable choice for generating XML, backed by community contributions.

  • cheerio:

    Cheerio has a strong community and is widely used in the web scraping domain. This means ample resources, tutorials, and community support are available for developers.

How to Choose: dom-serializer vs htmlparser2 vs xmlbuilder vs cheerio
  • dom-serializer:

    Opt for dom-serializer when you need to convert a DOM structure back into a string format. This is particularly useful when you have manipulated a document and want to output the final result as HTML or XML.

  • htmlparser2:

    Select htmlparser2 for a robust and efficient parsing solution that can handle both HTML and XML. It's suitable for projects requiring high performance and flexibility, especially when dealing with malformed HTML documents.

  • xmlbuilder:

    Use xmlbuilder if your primary goal is to create XML documents programmatically. It provides a simple and intuitive API for building XML structures, making it perfect for generating complex XML outputs.

  • cheerio:

    Choose Cheerio if you need a fast and flexible library for manipulating HTML documents using a jQuery-like syntax. It's ideal for web scraping and DOM manipulation tasks where you want to traverse and modify the document easily.

README for dom-serializer

dom-serializer Build Status

Renders a domhandler DOM node or an array of domhandler DOM nodes to a string.

import render from "dom-serializer";

// OR

const render = require("dom-serializer").default;

API

render

render(node: Node | Node[], options?: Options): string

Renders a DOM node or an array of DOM nodes to a string.

Can be thought of as the equivalent of the outerHTML of the passed node(s).

Parameters:

| Name | Type | Default value | Description | | :-------- | :--------------------------------- | :------------ | :----------------------------- | | node | Node | Node[] | - | Node to be rendered. | | options | DomSerializerOptions | {} | Changes serialization behavior |

Returns: string

Options

encodeEntities

Optional decodeEntities: boolean | "utf8"

Encode characters that are either reserved in HTML or XML.

If xmlMode is true or the value not 'utf8', characters outside of the utf8 range will be encoded as well.

default decodeEntities


decodeEntities

Optional decodeEntities: boolean

Option inherited from parsing; will be used as the default value for encodeEntities.

default true


emptyAttrs

Optional emptyAttrs: boolean

Print an empty attribute's value.

default xmlMode

example With emptyAttrs: false: <input checked>

example With emptyAttrs: true: <input checked="">


selfClosingTags

Optional selfClosingTags: boolean

Print self-closing tags for tags without contents.

default xmlMode

example With selfClosingTags: false: <foo></foo>

example With selfClosingTags: true: <foo />


xmlMode

Optional xmlMode: boolean | "foreign"

Treat the input as an XML document; enables the emptyAttrs and selfClosingTags options.

If the value is "foreign", it will try to correct mixed-case attribute names.

default false
