使用python将XML文件拆分为多个给定标记（例如：标记）

Question

嗨，我有一个大的xml文件，在这里我想分割成多个文件的xml文件的基础上的id（这里id是唯一的）。现在我有3个唯一的标记ID的xml文件，我想分裂他们。你知道吗

我的档案如下

main.xml文件

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tal xmlns="http://hello.com" schemaVersion="5.0.0" refSchemaFile="tal.xsd" status="Executable">
    <ExecProperties supportsParallelMostFlash="false"/>
    <talLine id="tl_1" status="Executable" baseVariant="DKOMBI8" diagAddress="60">
        <blFlash status="Executable">
            <blFlashTA status="Executable">
                <sgbmid>
                    <processClass>BTLD</processClass>

                </sgbmid>
            </blFlashTA>
        </blFlash>
    </talLine>
    <talLine id="tl_2" status="Executable" baseVariant="DKOMBI8" diagAddress="60">

            <swDeployTA status="Executable">

我需要每个“id”-在一个单独的文件与页眉和页脚（你可以观察下面的文件）的数据，上面是一个示例文件。我需要一个像下面这样的文件

1.xml

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tal xmlns="http://hello.com" schemaVersion="5.0.0" refSchemaFile="tal.xsd" status="Executable">
    <ExecProperties supportsParallelMostFlash="false"/>
    <talLine id="tl_1" status="Executable" baseVariant="DKOMBI8" diagAddress="60">
        <blFlash status="Executable">
            <blFlashTA status="Executable">
                <sgbmid>
                    <processClass>BTLD</processClass>
                    <id>00007732</id>
                    <mainVersion>2</mainVersion>
                    <subVersion>3</subVersion>
                    <patchVersion>11</patchVersion>
                </sgbmid>
            </blFlashTA>
            <blFlashTA status="Executable">
                <sgbmid>
                    <processClass>FLSL</processClass>
                    <id>00007735</id>
                    <mainVersion>2</mainVersion>
                    <subVersion>3</subVersion>
                    <patchVersion>11</patchVersion>
                </sgbmid>
            </blFlashTA>
        </blFlash>
    </talLine>
    <executionTime actualEndTime="0" actualStartTime="0" plannedEndTime="0" plannedStartTime="0"/>
    <installedECUList_Ist/>
    <installedECUList_Soll/>
</tal>

2.xml文件

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tal xmlns="http://hello.com" schemaVersion="5.0.0" refSchemaFile="tal.xsd" status="Executable">
    <ExecProperties supportsParallelMostFlash="false"/>
    <talLine id="tl_3" status="Executable" baseVariant="DKOMBI8" diagAddress="60">
        <cdDeploy status="Executable">
            <cdDeployTA status="Executable">
                <sgbmid>
                    <processClass>CAFD</processClass>
                    <id>00006d4e</id>
                    <mainVersion>0</mainVersion>
                    <subVersion>4</subVersion>
                    <patchVersion>11</patchVersion>
                </sgbmid>
            </cdDeployTA>
        </cdDeploy>
    </talLine>
    <executionTime actualEndTime="0" actualStartTime="0" plannedEndTime="0" plannedStartTime="0"/>
    <installedECUList_Ist/>
    <installedECUList_Soll/>
</tal>

3.xml

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tal xmlns="http://hello.com" schemaVersion="5.0.0" refSchemaFile="tal.xsd" status="Executable">
    <ExecProperties supportsParallelMostFlash="false"/>
    <talLine id="tl_2" status="Executable" baseVariant="DKOMBI8" diagAddress="60">
        <swDeploy status="Executable">
            <swDeployTA status="Executable">
                <sgbmid>
                    <processClass>SWFL</processClass>
                    <id>00007736</id>
                    <mainVersion>2</mainVersion>
                    <subVersion>3</subVersion>
                    <patchVersion>11</patchVersion>
                </sgbmid>
            </swDeployTA>
            <swDeployTA status="Executable">
                <sgbmid>
                    <processClass>SWFL</processClass>
                    <id>00007bfc</id>
                    <mainVersion>2</mainVersion>
                    <subVersion>3</subVersion>
                    <patchVersion>11</patchVersion>
                </sgbmid>
            </swDeployTA>
        </swDeploy>
    </talLine>
    <executionTime actualEndTime="0" actualStartTime="0" plannedEndTime="0" plannedStartTime="0"/>
    <installedECUList_Ist/>
    <installedECUList_Soll/>
</tal>

我试图用id删除一些特定的标记数据，但没有成功。你能给我一些更好的方法来实现我的目标吗。你知道吗

import xml.etree.ElementTree as ET
tree = ET.parse('main.xml')
root = tree.getroot()
mydata = root.find(".talLine[@id='tl_1']")
mydata.remove(mydata)

提前谢谢。你知道吗

Answer 1

我们只需要从根目录中找出标记的索引，清除它们并保存到新的xml文件中

import xml.etree.ElementTree as ET
mytree=ET.parse('D://talfiles//TAL_High_Hud_Dcs_002_003_011.xml')
myroot=mytree.getroot()
myroot[1].clear()
myroot[2].clear()
mytree.write('D://talfiles//1.xml')

然后输出将保存到新文件中

1.xml文件

<ns0:tal xmlns:ns0="http:hello.com" refSchemaFile="tal.xsd" schemaVersion="5.0.0" status="Executable">
<ns0:ExecProperties supportsParallelMostFlash="false" />
<ns0:talLine /><ns0:talLine /><ns0:talLine baseVariant="DKOMBI8" diagAddress="60" id="tl_3" status="Executable">
    <ns0:cdDeploy status="Executable">
        <ns0:cdDeployTA status="Executable">
            <ns0:sgbmid>
                <ns0:processClass>CAFD</ns0:processClass>
                <ns0:id>00006d4e</ns0:id>
                <ns0:mainVersion>0</ns0:mainVersion>
                <ns0:subVersion>4</ns0:subVersion>
                <ns0:patchVersion>11</ns0:patchVersion>
            </ns0:sgbmid>
        </ns0:cdDeployTA>
    </ns0:cdDeploy>
</ns0:talLine>
<ns0:executionTime actualEndTime="0" actualStartTime="0" plannedEndTime="0" plannedStartTime="0" />
<ns0:installedECUList_Ist />
<ns0:installedECUList_Soll />

但是这里我们面临的挑战是，我们需要避免在输出xml文件的每一行中使用ns0字符串
