当我传递特定参数时，使用ElementTree的iter()解析XML找不到我的标签

试图返回属性&标记中的值.按照ElementTree文档逐字逐句地进行任何操作都不会产生任何效果.没有错误，它只是运行并且不打印任何内容.如果我不带参数运行iter()，它将打印每个标签，但是带参数则不执行任何操作.不知道发生了什么.findall()也不起作用.

Trying to return attribute & values from a tag. Following the ElementTree documentation to word for word is producing nothing. No errors, it just runs and doesn't print anything. If I run iter() with no arguments it prints every single tag, but with an argument it does nothing. Not sure what's going on. The findall() doesn't work either.

如果我使用文档的XML，它可以正常工作，但不能与我的XML一起工作.我所看到的唯一区别是，文档xml的标签位于同一括号内.

If I use the doc's XML it works fine, but not with mine. Only difference I see are tags closed in the same bracket for the doc XML.

毫无疑问，我正在使用正确的Python版本，所以我很茫然.下面是我首先使用的XML，第二是Doc XML，以及运行它的代码.

I'm using the right version of Python without a doubt, so i'm at a loss. Below is my XML first, Doc XML 2nd, and the code to run it.
