从我的文件中"junk"的字符串报告中解析XML，我不知道如何找到它

Question

我正在尝试用元素树解析一个XML字符串。这个字符串来自许多连接在一起的dict值。没有根节点，但第一次运行良好。

我第一次这么做的时候就奏效了：

for value in data.values():
myxml = ' '.join(value)
tree = ET.fromstring(myxml)

但对于同样的情况，只是另一本字典，它不起作用。我的代码很简单：

values = [x for x in dict_fasi.values()]
myxml_fasi = ' '.join(values)
tree2 = ET.fromstring(myxml_fasi)

我也像以前一样尝试了循环，但没有成功。错误显示：xml.etree.ElementTree.ParseError:文档元素后的垃圾：第8行第20列。

第8行应为：

</new_line> <new_line>

XML字符串是：

<new_line>

相反，工作的第一个XML字符串是这样的：

也许这是new_line标签打开和关闭的问题，但我不知道如何解决

Answer 1

错误消息中的术语"垃圾"似乎是一个相当不公平的价值判断；但这意味着解析器希望看到一个顶级元素，当它到达该元素(以及任何尾随注释或PI(的末尾时，它希望看到文件的末尾。如果有另一个元素开始标记，那么它就不是一个格式良好的XML文档。

你说你知道没有根节点，但你似乎没有意识到这会使文档格式不正确。你说它第一次起作用：嗯，它不应该起作用。
