XMLGuy is a fluent, lightweight, flexible XML builder for .NET. It is heavily inspired by xmlbuilder-js.

• Upgrade to Visual Studio 2017
• Target Framework:
  • .Net Stanndard 2.0

var doc = new XmlDocument();

doc.Begin("organisation")
	.Add("staff")
		.Add("member", new { name = "Joe Smith", age = "45" }).Up()
		.Add("member", new { name = "Jane Smith", age = "48" }).Up()
		.Up()
	.Add("offices")
		.Add("office", new { name = "Head Office", location = "Balmain, Sydney" }).Up()
		.Up()
	.Add("revenue", "0").Up()
	.Add("description").CData("This organisation is a world class leader in excellence").Up()
	.Add("investors");

Console.WriteLine(doc.ToString(true)); // enable pretty formatting

This will produce

<?xml version="1.0" encoding="utf-8"?>
<organisation >
	<staff >
		<member name="Joe Smith" age="45"  />
		<member name="Jane Smith" age="48"  />
	</staff>
	<offices >
		<office name="Head Office" location="Balmain, Sydney"  />
	</offices>
	<revenue >0</revenue>
	<description >
		<![CDATA[This organisation is a world class leader in excellence]]>
	</description>
	<investors  />
</organisation>

You can download and build the source yourself.

As far as I know, XMLGuy produces valid XML for elements, attributes, text values and CData values.

It does not have an explict way of handling namespaces, but you can add them manually like this:

var doc = new XmlDocument();

var rss = doc.Begin("rss");
rss.Attributes = new Dictionary<string, string>()
{
	{"xmlns:content", "http://purl.org/rss/1.0/modules/content/"},
	{"xmlns:wfw", "http://wellformedweb.org/CommentAPI/"},
	{"xmlns:dc", "http://purl.org/dc/elements/1.1/"},
};

XMLGuy has not yet been extensively tested.

There are other libraries that attempt to make XML in .NET nicer to deal with, but they rely on the underlying .NET XML classes, which can make them a little clunky and inflexible. XMLGuy, on the other hand, simply builds up strings, so you're not bound by the limitations of those classes. Of course, this extra flexibility can mean that you can create invalid XML documents.

I also prefer the fluent paradigm that I borrowed from xmlbuilder-js.
