XSL entry

1.xsl --- xml style sheet

The HTML page uses a predetermined identity (tags), which means that all tags have a clear meaning, such as

is another line

is the title font. All browsers know how to resolve and display HTML web pages.

However, XML does not have a fixed logo, we can build our own identity, so the browser cannot automatically parse them, such as

3.xsl - what it can do?

XSL can be used to define how the XML document is displayed, and the XML document can be converted into an HTML file identified by the browser. It is usually, XSL is to achieve this conversion by translating each XML element "translated" as an HTML element. .

XSL can add new elements to the output file, or move the element. XSL can also rearrange or index data, which can detect and determine which elements are displayed, how much is displayed.
