Due to its superiority in extensibility and flexibility,XML has become the language over the internet. With more and more XML documents produced,the problem exists to transform them to other documents of various structures. This paper discusses and compares four methods to transform XML documents,then introduces XSLT,a W3C recommendation, by giving examples and outlining a project in brief.展开更多
