Motivation: I first thought of making a binary tree because I needed to make a company structure chart. The previous approach was to draw a picture directly using graphics software. It looks great, but you need to paint a new one every time there are changes. On the other hand, the display and layout of the lines on the webpage are quite limited. The dynamic generated data is very difficult to layout and positioning, and it is also unsatisfactory in beauty. After making various attempts, I decided to use XML+XSL as data operations; use VML to beautify the lines and use JavaScript to locate the object.

#: In order to facilitate users to view a large number of data, we will use dynamic paging, so the paging function is the most common and most commonly used functional module we have seen on the website. In the past, information paging was connected to the database, and every click required the support of the background database.

4. XML Volume Practical Tips (2): Dynamic Query
Introduction: The query function is the most common and commonly used functional module we have seen on the website.
