我有一些xml我正试图用Python2.7解析。XML的格式如下。在代码中(也包括在下面),如果我尝试使用collection.getAttribute('ProjectId')
打印,我会得到id号,但是一旦我将collection分配给tags
,然后通过一个循环运行它,我就不能得到输出(没有错误消息)。有什么线索吗?在

代码:
^{pr2}$
由于
collection.getElementsByTagName("SummaryReport")
不返回任何内容,因此没有输出:这是有意义的,因为
collection
已经引用了SummaryReport
元素,并且它没有同名的后代元素。在更新:
简单的
^{pr2}$for
循环可以很好地遍历Level
元素并打印值,例如:相关问题 更多 >
