由于最近需要使用C#處理IE的相關(guān)操作,因此積累了一些代碼,下面的代碼是從HTML代碼中生成DOM TreeView的例子:

//該過程將被遞歸調(diào)用
  //dom_node是當(dāng)前的HTML DOM節(jié)點
  //tree_node是當(dāng)前插入樹的結(jié)點
  PRivate void InsertDOMNodes(IHTMLDOMNode parentnode,TreeNode tree_node)
  {
  
   int sibing=0;//當(dāng)前結(jié)點在兄弟結(jié)點之間的順序,所有的結(jié)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);
  }
