XML 文档中存在错误 (1, 1) [英] There is an error in XML document (1, 1)

问题描述

我一直在尝试从 XML 读取数据.当我尝试反序列化它时，出现以下错误:

I have been trying to read data from XML. When I try to deserialize it, I get the following error:

XML 文档 (1, 1) 中存在错误."

"There is an error in XML document (1, 1)."

为了您的参考，我附上了我的整个代码以及我的 xml 文件.

For your reference, I am attaching my entire code as well as my xml file.

C# 代码:

CarCollection cars = null;
string path = @"C:\Users\harsha\Desktop\Doc.xml";
XmlSerializer serializer = new XmlSerializer(typeof(CarCollection));
var reader = XmlReader.Create(path);
cars = (CarCollection)serializer.Deserialize(reader);
reader.Close();

另外，数据结构如下:

namespace XMLDataReader
{
   [Serializable()]
   public class Car
   {
       [System.Xml.Serialization.XmlElement("StockNumber")]
       public string StockNumber { get; set; }

       [System.Xml.Serialization.XmlElement("Make")]
       public string Make { get; set; }

       [System.Xml.Serialization.XmlElement("Model")]
       public string Model { get; set; }
   }

   [Serializable()]
   [System.Xml.Serialization.XmlRoot("CarCollection")]
   public class CarCollection
   {
       [XmlArray("Cars")]
       [XmlArrayItem("Car", typeof(Car))]
       public Car[] Car { get; set; }
   }

XML 文件:

   <CarCollection>
<Cars>
  <Car>
    <StockNumber>1020</StockNumber>
    <Make>Nissan</Make>
    <Model>Sentra</Model>
  </Car>
  <Car>
    <StockNumber>1010</StockNumber>
    <Make>Toyota</Make>
    <Model>Corolla</Model>
  </Car>
  <Car>
    <StockNumber>1111</StockNumber>
    <Make>Honda</Make>
    <Model>Accord</Model>
  </Car>
</Cars>
</CarCollection>

等待一些帮助.提前致谢！

Waiting for some help. Thanks in advance!

推荐答案

就我而言，不知何故，序列化程序中存在错误.我不确定是库还是逻辑.

In my case, somehow, there is a bug in the serializer. I am not sure whether it's the library or the logic.

检查你是否有和我一样的情况:

To check whether you have the same case like me:

• 从您的数据库列中复制您的 XML，
• 打开记事本，
• 将 xml 粘贴到记事本中，
• 保存

它会告诉你它有问题:

如果继续按确定，则再次打开文件.那里会有一个问号:

If you continue to press Ok, then open the file again. There will be a question mark there:

为了解决这个问题，在反序列化xml字符串之前，我只是检查第一个字符是否是天使括号.如果不是，则删除该字符:

To solve this, before deserializing the xml string, I simply check whether the first character is an angel bracket or not. If not, then remove that character:

private static string Validate(string xml)
{
    if (string.IsNullOrEmpty(xml))
        return xml;

    try
    {
        var index = xml.IndexOf('<');
        if (index > 0)
            xml = xml.Substring(index);
    }
    catch { }

    return xml;
}
