Retrieving an XML document using Ajax
Retrieving an XML document using Ajax
http://www.javascriptkit.com/dhtmltutors/ajaxgetpost3.shtml
When making a server request in Ajax, the data returned can be in either
plain text/html, or an XML document instead. The later is technically
just a text file as well, but with some special instructions, Ajax can
retrieve that well formed XML text file and return it back to you as a
XML object. This enables the XML data to be easily parsed using
standard DOM
methods
.

"):
<?xml version="1.0" encoding="ISO-8859-1"?>

对于带有表空间xmlns的xml文件的解析，用正常解析文件的方法总是失效，不起作用，无法获得元素。
下面给出两种方法解析此类文件：
1.按正常解析xml文件的方法，需要注意几点：

只可以先取到根元素，一级一级往下取，eg：
Element root = document.g ......
