Convert OPML to WIKI XWIKI

OPML, or Outline Processor Markup Language, is a file format utilized primarily for outlining data structures. Initially developed in 2000 by UserLand Software, OPML was designed to facilitate the exchange of outline-based information between different software applications. Its uses have expanded over time, notably in organizing RSS feed lists and managing hierarchical data. The OPML file extension denotes XML-based documents that offer simplicity and interoperability in transferring structured information across diverse platforms. In essence, OPML serves as a versatile tool in the realm of data organization and syndication.

The XWiki Markup Language (WIKI) file extension is used in XWiki, an open-source enterprise wiki and collaborative platform. It facilitates the creation and formatting of wiki pages, enabling text formatting, embedding images, creating tables, and linking to other pages. The syntax was introduced to simplify content management and enhance collaboration. Over time, it has evolved to include advanced features like macros and scripting capabilities. This extension is integral to XWiki's functionality, supporting a wide range of applications from knowledge management to project documentation.
