使用Python minidom修改XML

Question

下面是一个示例XML文件：

<Project attri1="build">
    <Import Project="blahblah" xmlns="someURI" />
    <Property>
        ...
    </Property>
    <Property>
        ...
    </Property>
    ...
    <ItemGroup>
        <Folder Include="Scripts" />
        <Folder Include="Scripts/1.0" />
        <Folder Include="Scripts/2.0/" />
        ...
    </ItemGroup>
      ... some irrelevant ItemGroup is here
    <ItemGroup>
         <None Include="Scripts/1.0/001.sql" />
         <None Include="Scripts/2.0/002.sql" />
    </ItemGroup>
    ...
</Project>

上面的XML文件基于visualstudio的sqlproj文件的模板。是基于什么样的节点来区分的。在

我想使用Python的xml.dom.minidom库，并最终重写原始sqlproj文件。在

怎么做？在

如果您建议其他内置库，请举例说明，谢谢。在

关于如何区分ItemGroups，您没有提供足够的信息，但我假设这是基于内部节点的类型。在

下面是如何将新的Folder标记插入到Folders和None的ItemGroup中。其思想是找到第一个Folder和{}标记，获取父标记和appendChild到它：

import xml.dom.minidom

data = """<Project attri1="build">
    <Import Project="blahblah" xmlns="someURI" />
    <ItemGroup>
        <Folder Include="Scripts" />
        <Folder Include="Scripts/1.0" />
        <Folder Include="Scripts/2.0/" />
    </ItemGroup>
    <ItemGroup/>
    <ItemGroup>
         <None Include="Scripts/1.0/001.sql" />
         <None Include="Scripts/2.0/002.sql" />
    </ItemGroup>
</Project>"""

dom = xml.dom.minidom.parseString(data)

new_folder = dom.createElement('Folder')
new_folder.setAttribute('Include', 'newpath')

folder = dom.getElementsByTagName('Folder')[0]
folder.parentNode.appendChild(new_folder)

new_script = dom.createElement('Folder')
new_script.setAttribute('Include', 'newsql')

none = dom.getElementsByTagName('None')[0]
none.parentNode.appendChild(new_script)

print dom.toprettyxml()

它打印：
