使用python在xml文件中插入新行

我想在xml文件中的任何MeasureSymbolGroup行之间插入一行代码。我有一些代码，但工作不正常

我的代码：

tree = ET.parse(PATH_XML_FILE)
root = tree.getroot()
for sub in sorted(my_array):
    setSubValue = False
    for neighbor in root.iter('Command'):
        if "SWF" in str(neighbor.attrib):                
            if re.search(r"\b" + re.escape(sub) + r"\b", neighbor.text): # match whole word only
                setSubValue = True
                break

    if setSubValue == False:
        print sub
        f = ET.Element('Command Cmd="MeasureSymbolGroup" FlexType="SWF" LogIt="true"' + sub +'\n')

        neighbor.insert(1, f)
tree.write(output.xml')

其中my_数组是一个包含字符串列表的数组

基本xml文件：

<?xml version="1.0" encoding="utf-8"?>
<T1Automation>
    <Title>AutomationTest</Title>
    <LogFilePath>..\Result\log.html</LogFilePath>
    <Script Name="Group Measurement" GuiVisible="true" ShowTraces="true" StoreTraces="true" ShutdownConnection="false">
        <Commands>
            <Command Cmd="PrintTime" />            

            <Command Cmd="MeasureSymbolGroup" FlexType="SWF" LogIt="true">aaa</Command>             
            <Command Cmd="MeasureSymbolGroup" FlexType="SWF" LogIt="true">bbb</Command>

xml解析器会忽略标记之间的空间，那么为什么要特别关注您遇到的问题呢？请发布一个简单的例子。你看到我的新更新的例子文件了吗？请检查一次并给出一些想法。您尚未提供完整的代码或对您尝试执行的操作的清晰描述。Hello@Bhansa，我想在aaa bbb之间插入一行新行，但在我的代码中，它将在此代码之后插入。ccc ddd eee，但在这些行之后插入
