Optimized Presentation of XML Content
The internal representation of static web site content or dynamic data displayed on a web site is increasingly stored in XML format due to ever-widening support of XML in scripting languages, web browsers, and SQL databases. Before this semantically structured data is presented to the end user, it’s almost always transformed into browser-friendly HTML markup.
All of these solutions are suboptimal for the following reasons:
- If you perform XML-to-HTML conversion on the web server, you’re wasting server CPU cycles and increasing the page download time. (HTML output is almost always significantly larger than the corresponding XML data.)
In the following sections, you’ll learn how you can use the XSLT technology to reduce the document download time and server CPU utilizations for most of your visitors, while at the same time retaining compatibility with older browsers and ensuring visibility to search engines.
