c# - XmlTextReader ignores second and third Profile element

Question

I have the following XML file:

<?xml version="1.0"?><!--This document contains the profiles that have been created.--><Profiles>
  <Profile>
    <name>One</name>
    <date>Two</date>
  </Profile>
  <Profile>
    <name>One</name>
    <date>Two</date>
  </Profile>
  <Profile>
    <name>One</name>
    <date>Two</date>
  </Profile>
</Profiles>

The problem is that when I use XmlTextReader, it only reads the first profile and ignore the second and third.

    public ArrayList ReadProfiles() {

  ArrayList result = new ArrayList();
  Hashtable currentProfile = null;

  string currentName = "";
  string currentValue = "";  

  XmlTextReader textReader = new XmlTextReader(profilesPath);
  // Read until end of file
        while (textReader.Read()) {
   switch(textReader.NodeType) {

   case XmlNodeType.Text: {
    currentValue = textReader.Value;
    Debug.Log("found text = " + currentValue);
    }
    break;

   case XmlNodeType.Element: {
    currentName = textReader.Name;
    switch(currentName) {

    case "Profiles": 
     Debug.Log("found profiles");
     break;
    case "Profile":
     Debug.Log("found profile");
     break;
    case "name":
     Debug.Log("found name");
     break;
    case "date":
     Debug.Log ("found date");
     break;
    default:
     Debug.Log("default in");
     break;
    }
   }
    break;
   case XmlNodeType.Comment:
    Debug.Log("found comment");
    break;
   case XmlNodeType.EndElement:
    Debug.Log("found end element" + textReader.Name.ToString());
    break;
   default:
    Debug.Log("default out");
    break;
   }
  }

  textReader.Close();

  return result;
 }

so I get:

Answer 1

我的测试输出具有完全相同的代码和数据。将 Debug.Log 替换为 Writeline。

default out
found comment
found profiles
default out
found profile
default out
found name
found text = One
found end elementname
default out
found date
found text = Two
found end elementdate
default out
found end elementProfile
default out
found profile
default out
found name
found text = One
found end elementname
default out
found date
found text = Two
found end elementdate
default out
found end elementProfile
default out
found profile
default out
found name
found text = One
found end elementname
default out
found date
found text = Two
found end elementdate
default out
found end elementProfile
default out
found end elementProfiles
default out

这不是有效的 XML。XML 规范只允许一个根节点（处理指令不算作节点），并且您的输入流包含多个根节点。如果你把它通过验证器，它会呕吐。
