XMLDocument.Save adds return carriages to XML when elements are blank

This fixed it for me...

XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(@"C:\test.xml");//Save the xml and then cleanupXmlWriterSettings settings = new XmlWriterSettings { Indent = true };XmlWriter writer = XmlWriter.Create(@"C:\test.xml", settings);xmlDoc.Save(writer);

You control that through the XMLWriter within the Settings Property.

Check out this example along with the following references.http://msdn.microsoft.com/en-us/library/ms162618.aspx

Probably too late, but I referred to the solution given by Arvo Bowen. Arvo's solution is in C#, I wrote the same in Powershell Syntax

# $dest_file is the path to the destination file$xml_dest = [XML] (Get-Content $dest_file)##   Operations done on $xml_dest#$settings = new-object System.Xml.XmlWriterSettings$settings.CloseOutput = $true$settings.Indent = $true$writer = [System.Xml.XmlWriter]::Create($dest_file, $settings)$xml_dest.Save($writer)$writer.Close()

It solved my two problems:

• One, problem stated above i.e. newline character being added to null/empty values.
• Second, no end tag being created for null/empty values.ex: <tag1>$null</tag1> would actually be written in file as <tag />Refer this thread: Can we force XmlWriter to issue <my-tag></my-tag> rather than <my-tag/>?
