C＃XmlReader无法读取“

Question

我写了一个XML解析器，在InnerXml中，我得到了这样的文本：

<Name ...><<interface>>Employee</Name>
<!-- "<<interface>>Employee" is the InnerXml Text and I need it as string -->

我的阅读文字代码如下：

        public ClassObject AnalyzeName(XmlReader reader)
        {
            // new Class object where the name will be stored
           ClassObject classObject = new ClassObject();

            // XMLReader 
            while (reader.Read())
            {
                if (reader.Name == "Name" && reader.NodeType == XmlNodeType.Element)
                {
                    className = getName(reader.ReadSubtree());
                    classObject.name = className;
                }
           }
         return classObject;
       }



     string getName(XmlReader reader)
        {
            string className;
            while (reader.Read())
            {
                if (reader.HasValue)
                {
                    className += reader.Value;
                }
            }
            return className;
        }

但是在我的XmlTextReader阅读此行之后，我得到一个例外：

Nachricht: 
    System.Xml.XmlException : Ein Name darf nicht mit dem Zeichen '<', hexadezimaler Wert 0x3C, beginnen.

这意味着'

<Name...>&lt;&lt;interface&gt;&gt;Employee</Name> <!-- instead of <<interface>> -->

整个.grapml文件（这是一个不同的xml表示法：（位于y：NodeLabel）

Answer 1

在评论之后，我写了一个简单的代码片段，效果很好

var xmlReader = XmlReader.Create("...");
bool canRead = xmlReader.ReadToDescendant("y:NodeLabel");
if (canRead)
{
    var content = xmlReader.ReadElementContentAsString();
}
