) '& D _, l2aa? /M1 {2q just finished a small project using Ajax. The entire small project uses javascr javaspt as the client, PHP as the server, XMLHttpRequest as the interaction tool, and XML as the data transmission format. After that, I will make a brief summary and briefly analyze the advantages and disadvantages of using XML as the transmission format.

2. Both the server and client need to spend a lot of code to parse XML, regardless of the exception and complexity of the server and client code, and it is not easy to maintain the Java Chinese site Community Portal ry5kwob 'f6z
3. The method for parsing XML between different browsers on the client is inconsistent. You need to repeat a lot of code.
