Load and parse XML data using AJAX in jQuery

Use AJAX in jQuery to load XML data and parse/******* 1. Content-Type

02 in many cases, the problem of Content-Type cannot be resolved.

03 if it is an xml file, skip this step.

04 to dynamically generate XML, you must set it to text/xml. Otherwise, text/html is the common text by default.

05 set the Content-Type in common languages *********/

06

07 header ("Content-Type: text/xml"); // php

08 response. ContentType = "text/xml" // asp

09 response. setHeader ("ContentType", "text/xml"); // jsp

11 2. xml structure.

12 XML must be closed. It is very important!
