Change tag value in .csproj file with python

Question

my idea to replace named tag UrlPublish to my needed path on .csproj file , i need to do it 10 times(path1, path2, path3...) to create 10 different msbuild deployment manifests. i have a following code:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="15.0" DefaultTargets="Build">
  <Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')"/>
  <!--This section defines project-level properties.AssemblyNameName of the output assembly.ConfigurationSpecifies a default value for debug.OutputTypeMust be "Library" for VSTO.PlatformSpecifies what CPU the output of this project can run on.NoStandardLibrariesSet to "false" for VSTO.RootNamespaceIn C#, this specifies the namespace given to new files. In VB, all objects arewrapped in this namespace at runtime.-->

I try to using Python and xml parser. But if i try to find a PublishUrl tag i don't get changes ... my python code is :

   import xml.etree.ElementTree as ET
    tree = ET.parse('file.csproj')
    root = tree.getroot()
    elem = tree.findall(".//PublishUrl")
    print(elem)

How can i parse .csproj file? its not xml and i don't understand how can i replace tag value.

Answer 1

The problem is with xmlns. Try:

    import xml.etree.ElementTree as ET
    tree = ET.parse('file.csproj')
    root = tree.getroot()
    elem = tree.findall(".//{http://schemas.microsoft.com/developer/msbuild/2003}PublishUrl")
    print(elem)
