如何遍历XML文件中的每个子节点? [英] How can I iterate though each child node in an XML file?

问题描述

我有一个XML文件，我想遍历每个子节点收集信息的过程.

I have an XML File and i would like to iterate though each child node gathering information.

这是我的C#代码，它仅拾取一个节点，FieldData我想在其子节点上使用foreach.

Here is my C# code it only picks up one node, the FieldData i would like to use a foreach on its child nodes.

public void LoadXML() {
    if (File.Exists("Data.xml")) {
        //Reading XML
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load("Data.xml");

        //Think something needs to reference Child nodes, so i may Foreach though them

        XmlNodeList dataNodes = xmlDoc.SelectNodes("//FieldData"); 
        TagContents[] ArrayNode;

        foreach(XmlNode node in dataNodes) {
            int Count = 0;
            //int Max = node.ChildNodes.Count;
            ArrayNode = new TagContents[Max];

            ArrayNode[Count].TagName = node.Name;
            ArrayNode[Count].TagValue = node.SelectSingleNode(ArrayNode[Count].TagName).InnerText;
            Count = Count + 1;        
        }
    } else {
        MessageBox.Show("Could not find file Data.xml");
    }
}

我的XML看起来像:

My XML Looks Something like:

<?xml version="1.0"?>
<FieldData>
  <property_details_branch IncludeInPDFExport="Yes" Mod="20010101010101"/>
  <property_details_inspection_date IncludeInPDFExport="Yes" Mod="20120726200230">20120727220230+0200</property_details_inspection_date>
  <property_details_type_of_ownership IncludeInPDFExport="Yes" Mod="20120726134107">Freehold</property_details_type_of_ownership>
</FieldData>

推荐答案

您正在迭代FieldData节点，并且只有一个.要迭代其子节点，请输入:

You're iterating the FieldData nodes and you have only one. To iterate its child nodes write:

foreach (XmlNode node in dataNodes)
{
     foreach (XmlNode childNode in node.ChildNodes)
     {
