使用XmlReader C#查看元素的所有文本

Question

我正在使用XmlReader迭代一些XML.一些XML实际上是HTML,我想从节点获取文本内容.

示例XML:

<?xml version="1.0" encoding="UTF-8"?>
<data>
  <p>Here is some <b>data</b></p>
</data>

示例代码:

using (XmlReader reader = new XmlReader(myUrl))
{
  while (reader.Read()) 
  {
    if (reader.Name == "p")
    { 
      // I want to get all the TEXT contents from the this node
      myVar = reader.Value;
    }
  }
}

这不能得到我所有的内容.我如何从中获取所有内容

节点在那种情况下？

Answer 1

使用ReadInnerXml:

        StringReader myUrl = new StringReader(@"<?xml version=""1.0"" encoding=""UTF-8""?>
<data>
  <p>Here is some <b>data</b></p>
</data>");
        using (XmlReader reader = XmlReader.Create(myUrl))
        {
            while (reader.Read())
            {
                if (reader.Name == "p")
                {
                    // I want to get all the TEXT contents from the this node
                    Console.WriteLine(reader.ReadInnerXml());
                }
            }
        }

或者如果你想跳过这个<b>,你可以使用辅助读取器作为子树,只读取文本节点:

        StringReader myUrl = new StringReader(@"<?xml version=""1.0"" encoding=""UTF-8""?>
<data>
  <p>Here is some <b>data</b></p>
</data>");
        StringBuilder myVar = new StringBuilder();
        using (XmlReader reader = XmlReader.Create(myUrl))
        {
            while (reader.Read())
            {
                if (reader.Name == "p")
                {
                    XmlReader pReader = reader.ReadSubtree();
                    while (pReader.Read())
                    {
                        if (pReader.NodeType == XmlNodeType.Text)
                        {
                            myVar.Append(pReader.Value);
                        }
                    }
                }
            }
        }

        Console.WriteLine(myVar.ToString());
