解析重复子元素python

Question

我试图使用Python解析包含重复子元素的XML文档。当我试图解析数据时，它会创建一个空文件。如果我注释掉重复的子元素代码（请参阅下面python脚本中粗体部分），则文档将正确生成。有人能帮忙吗？在

Python脚本

Answer 1

示例XML和python代码在结构上不匹配。或者

• XML中缺少一个结束的</Gross>标记（应该在<HistoricReturns>部分开始之前）——在这种情况下，代码是正确的或者
• 代码应该是for node6 in node3.findall('./HistoricReturns'):，即node3，而不是{}

注意：XML示例不完整（它不是格式良好的XML），因为它缺少Gross、FRPerformanceShareClassCurrency和{}的结束标记，因此无法确定地回答问题。希望这有帮助。在
