将输出与 Linq 分隔到 Xml

Question

如何使用 Linq to Xml 强制一些节点之间的额外间距？我希望输出以下内容：

<root>

    <group>
        <leaf />
    </group>

    <group>
        <leaf />
    </group>

</root>

通过添加 Empty XText，它只会破坏格式。

var root =
    new XElement("root",
        new XText(""),
        new XElement("group",
            new XElement("leaf")),
        new XText(""),
        new XElement("group",
            new XElement("leaf")),
        new XText(""));

Console.WriteLine(root.ToString());

导致

<root><group><child /></group><group><child /></group></root>

Answer 1

这是一个解决方案，但它并不漂亮......

将 XText 更改为 XComment 并执行类似的操作...

 
    var root =
        new XElement("root",
            new XComment(""),
            new XElement("group",
                new XElement("leaf")),
            new XComment(""),
            new XElement("group",
                new XElement("leaf")),
            new XComment(""));

    Console.WriteLine(XElementToText(root));


    private string XElementToText(XElement element)
    {
        var sb = new StringBuilder();
        using (var writer = XmlWriter.Create(sb, 
            new XmlWriterSettings {Indent = true}))
        {
            element.WriteTo(writer);
        }
        return sb.ToString().Replace("<!---->", string.Empty);
    }

Answer 2

using (var writer = XmlWriter.Create(
    Console.Out,
    new XmlWriterSettings { Indent = true })
{
    root.WriteTo(writer);
}

Answer 3

将XmlTextWriter（Formatting 设置为Formatting.Indented）传递给root.WriteTo()。

例如：

using(var writer = new XmlTextWriter(Console.Out));
{
    writer.Formatting = Formatting.Indented;
    root.WriteTo(writer);
}
