XML

Introduction

---

From W3C, eXtensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to replace HTML and meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere. There are so many standards based on XML, see a survey of XML standards on IBM developerWorks.

See also WebStandard for XML validators.
