Besoin d'aide sur l'utilisation de XPathNavigator en C#?

Question

Mon fichier XML est comme suit. Il a mélangé le schéma et les éléments normaux.

<?xml version="1.0" encoding="utf-8"?> 
<!-- R1 --> 
<ax:root xmlns:ax="http://amecn/software/realtime/ax"> 
    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <xsd:element name="EquipmentConstants"> 
     <xsd:complexType> 
     <xsd:sequence> 
      <xsd:element minOccurs="0" maxOccurs="unbounded" ref="EquipmentConstant" /> 
     </xsd:sequence> 
     </xsd:complexType> 
     <xsd:unique name="id"> 
     <xsd:selector xpath=".//EquipmentConstant" /> 
     <xsd:field xpath="@id" /> 
     </xsd:unique> 
    </xsd:element> 
    ...... 
    ...... 
    </xsd:schema> 
    <EquipmentConstants xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <EquipmentConstant id="0"> 
     <Name>SerialNumber</Name> 
     <Group>SYSTEM</Group> 
     <Data> 
     <Value min="0" max="10000000" scale_factor="0" unit="U_NO_UNITS" permission="NolimitedAndNoChangeable" type="xsd_string" enum="" flag="0">0</Value> 
     </Data> 
     <Description>Serial Number</Description> 
    </EquipmentConstant> 
    ..... 
    ..... 
    </EquipmentConstants> 
</ax:root> 

Mon code C# comme ci-dessous. Je veux boucler les éléments de départ (par passer tout le contenu du schéma)

<EquipmentConstants xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

XPathDocument doc = new XPathDocument("test.xml"); 
       XPathNavigator navigator = doc.CreateNavigator(); 

       navigator.MoveToRoot(); // <?xml version="1.0" encoding="utf-8"?> 
       //navigator.MoveToFirstChild(); // <!-- R1 --> 
       // 1st, I tried to use MoveToChield(), But I failed to move there. 
       navigator.MoveToChild("EquipmentConstants"); 
       // Then, I also tried to use SelectSingleNode(). But I failed too. 
       navigator.SelectSingleNode("ax/EquipmentConstants"); 
       while (navigator.MoveToNext()) 
       { 
       // do something. 
       } 

Pourriez-vous s'il vous plaît me donner quelques suggestions. Je vous remercie.

Answer 1

Ma solution comme ci-dessous.

  XPathDocument doc = new XPathDocument("test.xml"); 
      XPathNavigator navigator = doc.CreateNavigator(); 

      navigator.MoveToRoot(); // <?xml version="1.0" encoding="utf-8"?> 
      navigator.MoveToFirstChild(); // <!-- R1 --> 
      navigator.MoveToNext(); // <ax:root xmlns:ax="http://amecn/software/realtime/ax"> 
      navigator.MoveToChild("EquipmentConstants", ""); // <EquipmentConstants xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 

      navigator.MoveToFirstChild(); // <EquipmentConstant id="0"> 
      do 
      { 
      // Loop body; 
      } while (navigator.MoveToNext());

 XPathNavigator navigator = doc.CreateNavigator(); 
     if (navigator == null) 
     { 
      return; 
     } 
     foreach (XPathNavigator nav in 
      navigator.Select("/" + "EquipmentConstants" + "/" + "EquipmentConstant")) 
     { 

     }
