在JSP、ASP和PHP网站网页中使用XHTML
时间:2008-01-12 编辑:简简单单 来源:一聚教程网
A wise programmer once said, "The one constant in computing is change." There couldn't be a truer
statement. This article is about such change, specifically moving from HTML to the next generation, XHTML
(Extensible Hypertext Markup Language).
This article includes the following sections:

The analysis is from a server-side perspective, meaning it applies equally well to ASP, JSP, PHP or other
server-side driven projects.
An Introduction to XHTML
XHTML (now in version 1.1) is the merging of HTML 4 and XML. It represents such an important advancement
that the World Wide Web Consortium (W3C), the international standards body for the web, is replacing HTML
with XHTML as the standard tool for creating web pages.
XHTML is built to open doors to other formats. For example, XHTML can be used to format content for
pagers, whereas HTML cannot. XHTML will replace WAP and other markup languages. It is a cornerstone in the
revolutionary change in thinking beginning to occur in web site design. Instead of viewing a web site as a
stand alone data island, XHTML will expand web applications, allowing web sites to control and send
information which will drive countless devices, presentation styles and other web sites. XHTML is the
starting point for this tremendous change we are about to experience in how we use the web.
Using XHTML has many advantages over using HTML. Because of its structure, XHTML is faster. Its well
formed documents result in quicker and smaller parsers. These smaller parsers waste less time verifying
and doing logic sorting that's required for hodge podge HTML documents. While faster results are not
available yet, expect improved performance from the next generation of XHTML-based browsers.
