     foreach (var node in doc.SelectNodes("//string"))

                if (elem.InnerText == "software-package")
                {
                    var versionElement = elem.NextSibling.NextSibling as XmlElement;
                    if (versionElement != null)
                    {
                        versionElement.InnerText = "PCDownload Url";

I think your issue has to do with the XmlDocument.Save() method. As you already know, XML and plist files are slightly different, but the Save() method is trying to apply XML properties to your plist when saving.

Here are some options:

1) Use regular expressions. Buffer the file contents into a byte[], make your changes using regular expressions, and then write that buffer to .plist.

2) Parse the document using the XML parser, but don't use the built in Save() method. This may still result in unwanted modifications in the plist file, but it's worth a shot.
