当我基于PHP的web服务时，我得到了解析的一些问题。我从2天仍然陷入困境。我无法在Activity中获得任何输出。当我在Handler中打印时，我成功打印了变量。
这里有一些logcate：SAX解析器提出了一些错误

看来你的XML格式不正确格式化（可能有特殊字符）。我会建议记录xml，并确保你得到正确的xml。 – kosa 2012-02-08 16:07:03
你可以显示你正在尝试解析的XML吗？ – 2012-02-08 16:11:35
如果你的xml格式正确，我会看看这里：http://stackoverflow.com/questions/8827006/sax-expatparserparseexception。 – javanna 2012-02-08 18:02:21
