android天气预报 sax解析报错,该如何处理

android天气预报 sax解析报错

天气预报API地址：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getWeatherbyCityName?theCityName=beijing

<?xml version="1.0" encoding="utf-8" ?> - <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://WebXml.com.cn/">
<string>直辖市</string> 

<string>北京</string> 

<string>54511</string> 

。。。。。

</ArrayOfString>

整个天气预报的XML只有一个<string>元素，代码看了很久感觉没什么问题，onclick后报异常。后来单步调试运行发现 执行完第一次startElement后立马就报错了。DEBUG视图 弹出一个ExpatParser.startElement（。。。）的标签页 内部标注了一行文本“Source not found.”
我这个代码应该怎么改~~真心不知道怎么办了
