GNU M4 features and specs

• Portability
  GNU M4 is highly portable and can run on almost any Unix-like operating system, which makes it versatile for various environments.
• Macro Capabilities
  It offers powerful macro processing features that are useful for a wide range of text processing tasks, such as configuring scripts, code generation, and templating.
• Simplicity
  M4 is relatively simple to use for basic macro processing tasks, which makes it accessible to new users and suitable for straightforward applications.
• Integration
  GNU M4 often integrates well with other tools and scripts, making it a useful component in build systems and automated workflows.

Possible disadvantages of GNU M4

• Limited Built-in Functions
  Compared to more modern scripting languages, M4 lacks a wide range of built-in functions and features, which may limit its use for more complex tasks.
• Steep Learning Curve
  While simple tasks are easy to set up, mastering M4 for more advanced uses can require a deeper understanding of its syntax and capabilities.
• Debugging Difficulty
  Debugging macros in M4 can be challenging, especially for large scripts, due to the lack of advanced debugging tools and support.
• Performance Considerations
  For very large and complex scripts, performance may become an issue, as M4 is not optimized for handling large-scale data manipulation compared to more modern alternatives.

Xidel features and specs

• Versatile Data Extraction
  Xidel supports extracting data from numerous formats such as XML, HTML, JSON, and various web services which makes it adaptable for different scraping tasks.
• Powerful Query Languages
  It utilizes powerful query languages like XPath, XQuery, and JSONiq, allowing for complex data extraction and transformation operations.
• Command-Line Interface
  Its CLI nature makes it suitable for integration into scripts and automatons, which is useful for developers and power users.
• Open Source
  Being open-source software, Xidel can be modified and improved by the community, and it’s freely available for anyone to use and redistribute.

Possible disadvantages of Xidel

• Steep Learning Curve
  For those who are not familiar with XPath, XQuery, or JSONiq, there might be a steep learning curve to effectively use Xidel.
• Limited GUI
  As a command-line tool, Xidel lacks a graphical user interface, which might not be as user-friendly for those who prefer visual tools.
• Less Community Support
  Compared to more popular web scraping tools like Beautiful Soup or Scrapy, Xidel has a smaller community, which might make finding help or resources more difficult.
• Platform Compatibility
  While Xidel is designed to be cross-platform, ensuring it runs smoothly across all operating systems without specific configurations can sometimes be challenging.
