Get the confs

Input collapsed: 
from surun_tools.glob1 import glob_files
glob_files("*.vcxproj")

[WindowsPath('C:/src/surun/src/PC/InstallSuRun.vcxproj'),

some confs are test projects. filter out them

proj_files = list(filter(lambda x: "test" not in str(x), glob_files("*.vcxproj")))
proj_files

Select a demo proj file

ext_proj = glob_files("*.vcxproj")[2]

print(ext_proj)

Test gradually

remove("ItemGroup/ProjectConfiguration")

remove("PropertyGroup")

remove("ImportGroup")

remove("ItemDefinitionGroup")

remove("ItemGroup/CustomBuild/ExcludedFromBuild")

Put it all together

from pathlib import Path
for i in proj_files:
    tree2 = etree.parse(i, parser)
    ns = {"default": "http://schemas.microsoft.com/developer/msbuild/2003"}

    def remove(tag, tag2="Condition"):
        tag = "/".join(map(lambda x: "default:" + x, tag.split("/")))
        root = tree2.getroot()

        for j in root.findall(f"{tag}", ns):
            if tag2 not in j.attrib:
                continue
            if not is_correct_conf(j.attrib[tag2]):
                j.getparent().remove(j)

        tree2.write(i, encoding="utf-8", xml_declaration=True)

        content = Path(i).read_text(encoding="utf8")
        content = content.replace("ns0:", "").replace(":ns0", "").replace('/>', ' />')
        Path(i).write_text(content, encoding="utf8")
    remove("ItemGroup/ProjectConfiguration")
    remove("PropertyGroup")
    remove("ImportGroup")
    remove("ItemDefinitionGroup")
    remove("ItemGroup/CustomBuild/ExcludedFromBuild")

for sln files

remove these:

GlobalSection(SolutionConfigurationPlatforms) = preSolution
		Debug|Win32 = Debug|Win32 <-
		Debug|x64 = Debug|x64     <-
...
EndGlobalSection

for this file we can see that only conf contains | symbol. we can use that.

sln:Path = glob_files("*.sln")[0]
print(sln)

C:\src\surun\src\PC\SuRun.sln

content = sln.read_text(encoding="utf8")
text = []
for i in content.split("\n"):
    if "|" in i:
        if not is_correct_conf(i):
            continue
        else:
            text.append(i)
    else:
        text.append(i)
sln.write_text("\n".join(text), encoding="utf8")
