如何在 C# 中使用 XMLWriter 将字符串（XML 节点格式化为无根节点）编写为节点？

Question

我正在尝试使用 XMLWriter

将字符串（只不过是 XML 节点）写入新的 XML 文件

XmlWriter writer = XmlWriter.Create(@"C:\Test.XML")
writer.WriteStartDocument();
writer.WriteStartElement("Test");

string scontent = "<A a="Hello"></A><B b="Hello"></B>";
XmlReader content = XmlReader.Create(new StringReader(scontent));
writer.WriteNode(content, true);
//Here only my first node comes in the new XML but I want complete scontent
writer.WriteEndElement();

预期输出：

<Test>
<A a="Hello"></A>
<B b="Hello"></B>
</Test>

Answer 1

试试这个...在 ""

之前使用 \

XmlWriter writer = XmlWriter.Create(@"C:\Test.XML")
writer.WriteStartDocument();
writer.WriteStartElement("Test");

string scontent = "<A a=\"Hello\"></A><B b=\"Hello\"></B>";
XmlReader content = XmlReader.Create(new StringReader(scontent));
writer.WriteNode(content, true);
//Here only my first node comes in the new XML but I want complete scontent
writer.WriteEndElement();

您必须指定 ConformanceLevel，因为您的 xml 没有根元素。

也总是应该处理所有使用的资源。

using (XmlWriter writer = XmlWriter.Create(@"C:\Test.XML"))
{
    writer.WriteStartDocument();
    writer.WriteStartElement("Test");

    string scontent = "<A a=\"Hello\"></A><B b=\"Hello\"></B>";

    var settings = new XmlReaderSettings();
    settings.ConformanceLevel = ConformanceLevel.Fragment;

    using (StringReader stringReader = new StringReader(scontent))
    using (XmlReader xmlReader = XmlReader.Create(stringReader, settings))
    {
        writer.WriteNode(xmlReader, true);
    }

    writer.WriteEndElement();
}

此外，您可以使用XmlWriterSettings添加缩进。
