When developing a system, it is common to get its description by code, for example, to get an error message from an error number.

This is called the separation of data and display, which is very good. When we want to change the wind, we only need to change the XSL and do not need to add a new copy of data. But sometimes there are special cases. For example, we have this strange requirement-writing XMLXSL to a file. There was no result after Baidu; suddenly, there was no popular Q A website

3. long data search time. HTML is mainly used to control the display of web pages. as a result, the same data has different storage formats on different web pages. in this way, you cannot quickly find the desired information during data search.
4. HTML does not support double-byte or multi-country text. For example,

To learn XSL, you must be familiar with XPath. XSL is as simple and powerful as XPath and is easy to learn.
