Python 从xml获取用户数据

我想从xml中提取行。以下是一个例子：

<userData code="viPartListRailML" value="1">
            <partRailML s="0.0000000000000000e+00" id="0"/>
            <partRailML s="2.0000000000000000e+01" id="1"/>
            <partRailML s="9.4137883373059267e+01" id="2"/>
        </userData>
        <userData code="viBaliseList" value="1">
        </userData>
        <userData code="viAxleCounterList" value="1">
        </userData>

预期结果如下：

<userData code="viPartListRailML" value="1"><partRailML s="0.0000000000000000e+00" id="0"/><partRailML s="2.0000000000000000e+01" id="1"/><partRailML s="9.4137883373059267e+01" id="2"/></userData>

你能帮我找出我的错误吗

您期望的输出是什么？您需要从xml文件中获取带标记的整行？是的，我需要它，就像选择

userData

是基于什么<代码>viPartListRailML？

<userData code="viPartListRailML" value="1"><partRailML s="0.0000000000000000e+00" id="0"/><partRailML s="2.0000000000000000e+01" id="1"/><partRailML s="9.4137883373059267e+01" id="2"/></userData>
