Remove unwanted (empty) xmlns attribute added by appendChild

Question

I have this code:

function setupProject($projectFile) {
  [xml]$root = Get-Content $projectFile;

  $project = $root.Project;

  $beforeBuild = $root.CreateE         


        

Answer 1

As answered by Michael Kay, the best way to remove this unwanted namespace is creating the new child element in the same namespace as its parent:

function setupProject($projectFile) {
  [xml]$root = Get-Content $projectFile;

  $project = $root.Project;

  # UPDATE THIS LINE $beforeBuild = $root.CreateElement("Target", "");
  $beforeBuild = $root.CreateElement("Target", $project.NamespaceURI);
  $beforeBuild.SetAttribute("name", "BeforeBuild");
  $beforeBuild.RemoveAttribute("xmlns");
  $project.AppendChild($beforeBuild);

  $root.Save($projectFile);
}
