Print all xml child node using python

Question

I want to print all the values of the "ClCompiler" child of "ItemGroup" of my xml file.

my python code

tree = minidom.parse(project_path)
itemgroup = tree.getElementsByTagName('ItemGroup')
print (itemgroup[0].toxml())

my result

<ItemGroup Label="ProjectConfigurations">
    <ProjectConfiguration Include="Debug|Win32">
        <Configuration>Debug</Configuration>
        <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="Release|Win32">
        <Configuration>Release</Configuration>
        <Platform>Win32</Platform>
    </ProjectConfiguration>
</ItemGroup>
<ItemGroup>
    <ClCompile Include="../../avmedia/source/framework/MediaControlBase.cxx"/>
    <ClCompile Include="../../avmedia/source/framework/mediacontrol.cxx"/>
    <ClCompile Include="../../avmedia/source/framework/mediaitem.cxx"/>
    <ClCompile Include="../../avmedia/source/framework/mediamisc.cxx"/>
</ItemGroup>

ecc

expected result

    <ClCompile Include="../../basic/source/basmgr/basmgr.cxx"/>         
    <ClCompile Include="../../basic/source/basmgr/vbahelper.cxx"/>      
    <ClCompile Include="../../basic/source/classes/codecompletecache.cxx"/>

ecc

part of my xml

<ItemGroup>
    <ClCompile Include="../../basic/source/basmgr/basicmanagerrepository.cxx"/>
    <ClCompile Include="../../basic/source/basmgr/basmgr.cxx"/>
    <ClCompile Include="../../basic/source/basmgr/vbahelper.cxx"/>
    <ClCompile Include="../../basic/source/classes/codecompletecache.cxx"/>
</ItemGroup>

An alternate solution using ElementTree,

import xml.etree.ElementTree as ET
root = ET.fromstring('''\
<ItemGroup>
<ClCompile Include="../../avmedia/source/framework/MediaControlBase.cxx"/>
<ClCompile Include="../../avmedia/source/framework/mediacontrol.cxx"/>
<ClCompile Include="../../avmedia/source/framework/mediaitem.cxx"/>
<ClCompile Include="../../avmedia/source/framework/mediamisc.cxx"/>
</ItemGroup>
''')

for child in root.iter('ClCompile'):
    print(ET.tostring(child))

While parsing from file,

import xml.etree.ElementTree as ET
tree=ET.parse('text.xml')
root = tree.getroot()
for child in root.iter('ClCompile'):
    print(ET.tostring(child))

You made it half way.
You found all the ItemGroup nodes in the document. Now, you have to iterate through each of them and find its ClCompile children (most likely only one of them will have such children).

Here's the code:

from xml.dom import minidom

project_path = "./a.vcxproj"
item_group_tag = "ItemGroup"
cl_compile_tag = "ClCompile"


def main():
    tree = minidom.parse(project_path)
    item_group_nodes = tree.getElementsByTagName(item_group_tag)
    for idx, item_group_node in enumerate(item_group_nodes):
        print("{} {} ------------------".format(item_group_tag, idx))
        cl_compile_nodes = item_group_node.getElementsByTagName(cl_compile_tag)
        for cl_compile_node in cl_compile_nodes:
            print("\t{}".format(cl_compile_node.toxml()))


if __name__ == "__main__":
    main()

Notes:

I ran the code with Python 3.4 (since no version was mentioned in the question). 2.7 compatibility will require some minor changes.
I did my tests on a VStudio project where the second search tag was ClInclude, but I guess that's an fairly old version.
The 1^st print line is only for illustrating the parent ItemGroup node. Comment it out to achieve your desired output.
Needless to say that you should modify project_path to point to your project file.
