Xml file parsing (output in RootTableViewController after parsing), tableviewcontroller

Xml file parsing (output in RootTableViewController after parsing), tableviewcontroller

 

 

This is the xml file, region, and latitude and longitude obtained from Meituan.

After you click the region, you can view the longitude and latitude. Because I am lazy and have ready-made text boxes, all of them are lazy.

 

Below are some boring code.
