Extensible Stylesheet Language Transformations, or XSLT, is an XML-based language used for the transformation of XML documents. The original document is not changed; rather, a new document is created based on the content of an existing one. The new document may be serialized (output) by the processor in standard XML syntax or in another format, such as HTML or plain text. XSLT is most often used to convert data between different XML schemas or to convert XML data into web pages or PDF documents.
XSLT was produced as a result of the Extensible Stylesheet Language (XSL) development effort within W3C during 1998–1999, which also produced XSL Formatting Objects (XSL-FO) and the XML Path Language, XPath. The editor of the first version (and in effect the chief designer of the language) was James Clark. The version most widely used today is XSLT 1.0, which was published as a Recommendation by the W3C on 16 November 1999. A greatly expanded version 2.0, under the editorship of Michael Kay, reached the status of a Candidate Recommendation from W3C on 3 November 2005.

XSLT를 잘 이용하는 곳의 하나로 feedburner를 뽑고 싶다. 한때 MS XSLT 구현 방법에 대해서 말도 많고 탈도 많았으나... 뭐 어쨋든 나름대로들 잘 사용하고 있는 듯 보임.
MSXML 을 이용해서 만들어진 XML을 HTML로 변환하여 얻어내는 것이 가능함. MSDN 참조
XML+CSS 로는 데이터의 바꾸는 것이 불가능하지만 XSLT를 이용할 경우 아예 XML 구조 자체를 변경하는 것이 가능하다. - eternalbleu
