Question

因此在使用Yahoo的Sports API进行查询后，我开始尝试使用python中的lxml解析XML：我已经尝试在将它们存储在根目录中后获取元素，如果我只是使用它，我可以访问子标记索引;但是调用root.find（“season”）这样的东西什么也不返回。基于我读过的其他帖子，我相信这可能与xml文件中使用的命名空间有关。我应该如何处理这个问题，以便获得我需要的元素？

编辑：我很抱歉不够清楚。我试图看看NFL QB Andrew Luck。代码访问root [0] [1]。 root [0]应该是播放器标签，但播放器标签内有很多子节点，因此root [0] [0]是它的第一个子节点，player_key标签，root [0] [1]是播放器标签的第二个子节点，应该是player_id标签。

但是调用root [0] .find（'player_id'）或find的任何变体，iter方法都不会返回任何内容。

再次感谢您的帮助！

以下是xml代码
