推荐答案

我建议尽可能使用真正的支持名称空间的XML解析器，尤其是在处理外部服务时.例如，不能保证名称空间前缀会随着时间的推移保持不变.

I recommend using a real namespace-aware XML parser if at all possible, especially when dealing with external services. There is no guarantee that the namespace prefix will remain constant over time, for example.

大多数JavaScript DOM解析器将包含getElementsByTagNameNS()，可让您查找具有实际名称空间的元素.

Most JavaScript DOM parsers will include getElementsByTagNameNS(), which will let you find elements with the actual namespace.

假设您的数据位于xml_file中，则该过程可能类似于以下内容.

The process might look something like this, assuming your data was in xml_file.

var namespace = 'http://aws.example.com/';
var parser = new DOMParser(); // Webkit, IE has its own
var xml = parser.parseFromString(xml_file, "text/xml");    
var year = xml.getElementsByTagNameNS(namespace, 'year')[0]; // returns the first aws:year element
var year_value = year.getAttribute('number');
