Convert XML DOCBOOK to TEXT MARKDOWNPHPEXTRA

DocBook XML, a subset of XML (Extensible Markup Language), serves as a markup language tailored for technical documentation. Developed in the early 90s, it was designed to standardize documentation across various software systems. Its uses include creating structured documents like books, articles, and manuals, ensuring consistency and ease of content transformation across different formats such as HTML, PDF, and EPUB. This standardization facilitates collaboration among developers and writers, enhances content reuse, and simplifies documentation maintenance.

The TEXT file extension, associated with PHP Markdown Extra Documentation, refers to plain text files used to write and store documentation. These files are simple, human-readable, and can be easily converted to HTML using Markdown syntax. The TEXT extension is commonly used for README files, configuration files, and other documentation purposes. Markdown Extra enhances the basic Markdown syntax with additional features like tables, footnotes, and definition lists, making it a powerful tool for creating well-structured documentation.
