XSLT allows you to create formatting structures which interpret and modify the existing XML elements. Learn about the syntax of XSLT elements, how the namespace attribute differs depending on the browser in use, and how to transform original XML elements.
Before this will actually work, you need to link the XLST file to the existing XML file, to do this, open the original XML file (news.xml if you're following on from the previous article) and add the following line of code directly below the XML declaration at the top:
Now save this file with the name transformedNews.xml and then open it in a browser. You should see a page with the Today's News heading at the top of the page, and the two news stories with their associated headings below this. If you open the XSL file, it will look very similar to a flat XML file, with the declaration and tags in blue and the elements in red. Additionally, XSLT elements will appear in a nice shade of purple.
