将XML文件分割成多个给定标签，例如：使用python的标签

Question

[我有一个大的xml文件，在这里我想根据id将xml文件分成多个文件（这里的id是唯一的）。目前有一个带有3个唯一标记ID的xml文件，我想将它们拆分。

我的文件如下

main.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">

我需要在具有页眉和页脚的单个文件中找到每个“ id”数据（您可以观察以下文件），上面是示例文件。我需要如下所示的随地吐痰的文件

1.xml

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>

    <talLine id="tl_1" status="Executable" baseVariant="DKOMBI8" diagAddress="60">
        <blFlash status="Executable">
            <blFlashTA status="Executable">
                <sgbmid>

我试图删除一些带有ID的特殊标签数据，但没有运气。您能为我提出实现目标的更好方法吗？

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

提前感谢。

Answer 1

我们只需要从根目录中找到标签的索引并清除它们，然后保存到新的xml文件中

import xml.etree.ElementTree as ET

mytree = ET.parse（'D：//talfiles//TAL_High_Hud_Dcs_002_003_011.xml'）
