XmlWriterSettings.NewLineOnAttributes is ignored on writing xmlns:* attributes #74840
Description
Description
As described in the title.
XmlWriterSettings.NewLineOnAttributes is applied to normal attributes properly, but seems not to be applied to xmlns attributes.
This problem seems to occur with both case of xmlns="..." and xmlns:nsname="...".
Reproduction Steps
Code for reproduction:
using System.Xml;
using System.Xml.Linq;
var nsSvg = (XNamespace)"http://www.w3.org/2000/svg";
var nsXLink = (XNamespace)"http://www.w3.org/1999/xlink";
var doc = new XDocument(
new XDeclaration("1.0", "utf-8", null),
new XElement(
nsSvg + "svg",
new XAttribute("version", "1.1"),
new XAttribute("width", "10"),
new XAttribute(XNamespace.Xmlns + "xlink", nsXLink.NamespaceName),
new XAttribute("height", "10"),
new XElement(nsSvg + "g")
)
);
var settings = new XmlWriterSettings() {
CloseOutput = false,
Indent = true,
IndentChars = " ",
NewLineChars = "\n",
NewLineOnAttributes = true
};
using (var writer = XmlWriter.Create(Console.Out, settings)) {
doc.Save(writer);
}
Console.WriteLine();Note: The same problem occurs with XDocument created from XDocument.Load.
var reader = new StringReader(@"<?xml version=""1.0"" encoding=""utf-8""?>
<svg
version=""1.1""
xmlns=""http://www.w3.org/2000/svg""
width=""10""
xmlns:xlink=""http://www.w3.org/1999/xlink""
height=""10""
>
<g />
</svg>
");
var doc = XDocument.Load(reader);Expected behavior
<?xml version="1.0" encoding="utf-8"?>
<svg
version="1.1"
width="10"
xmlns:xlink="http://www.w3.org/1999/xlink"
height="10"
xmlns="http://www.w3.org/2000/svg">
<g />
</svg>Actual behavior
<?xml version="1.0" encoding="utf-8"?>
<svg
version="1.1"
width="10" xmlns:xlink="http://www.w3.org/1999/xlink"
height="10" xmlns="http://www.w3.org/2000/svg">
