Convert OPML to TXT

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.

A TXT file, short for "Text", is a digital document that contains plain text without any formatting. It is universally compatible across different operating systems and software applications, making it ideal for storing data in a simple, accessible format. The history of TXT files dates back to the earliest days of computing, where simplicity and interoperability were paramount. Widely used for coding, scripting, documentation, and data exchange, TXT files remain a fundamental component in various IT environments due to their efficiency and versatility.
