Convert OPML to UOT

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 UOT (Uniform Office Document) file extension is used for documents created in the Uniform Office Format (UOF), an open standard developed for Chinese office productivity applications. It uses an XML format to describe the document and is compressed to reduce file size. UOT files can be opened by OpenOffice and its variants. The format is similar to the OASIS OpenDocument format but is not compatible with it.
