C#中從HTML產生DOM TreeView的代碼

dom|treeview

由於最近需要使用C#處理IE的相關操作,因此積累了一些代碼,下面的代碼是從HTML代碼中產生DOM TreeView的例子:

//該過程將被遞迴調用
  //dom_node是當前的HTML DOM節點
  //tree_node是當前插入樹的結點
  private void InsertDOMNodes(IHTMLDOMNode parentnode,TreeNode tree_node)
  {
  
   int sibing=0;//當前結點在兄弟結點之間的順序,所有的結點之間通過","隔開
   if(parentnode.hasChildNodes())
   {
    //level++;
    //pathstring = pathstring +","+ level;
    IHTMLDOMChildrenCollection allchild = (IHTMLDOMChildrenCollection)parentnode.childNodes;
    int length = allchild.length;
    for(int i=0;i<length;i++)
    {
     string instring = pathstring;
     instring = instring +","+ sibing++;
     IHTMLDOMNode child_node = (IHTMLDOMNode)allchild.item(i);
     TreeNode tempnode = tree_node.Nodes.Add(child_node.nodeName +"_"+instring);
     //string tmp =
     InsertDOMNodes(child_node,tempnode);
     pathstring = instring;
    }
   }
  }
  private void eVIPSBrowser_DocumentComplete(object sender, AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
  {
   pathstring ="0";
   level = 0;
   DOMTreeView.Nodes.Clear();
   IHTMLDocument3 HTMLDocument =(IHTMLDocument3)eVIPSBrowser.Document;
   IHTMLDOMNode rootDomNode = (IHTMLDOMNode)HTMLDocument.documentElement;
  
   TreeNode root = DOMTreeView.Nodes.Add("HTML"+"_"+pathstring);
   InsertDOMNodes(rootDomNode,root);
  }
