Migrating from HTML to XML

As the Internet world shifts its focus to XML and related technologies, what happens to HTML? Everywhere you go, products are becoming 'XMLitized' as vendors rush to gain market share. While this is great for companies that are only now beginning to build their infrastructures, what about the rest of us whose sites have existed for years, accumulating documents architected on old HTML technology? How are we to take our millions and millions of HTML documents and bring them into the next generation of Internet computing? Fortunately, the market for tools in this space is growing, and technologies like Extensible Hypertext Markup Language (XHTML) are making it easier to migrate your repository of existing HTML documents.
