Answer 1

HtmlElement he = wb.Document.All["regMarketForm"];
                for (int i = 0; i < he.All.Count; i++)
                {
                    if (he.All[i].GetAttribute("属性").IndexOf("值") >= 0)
                    {
                    }
                }

Answer 2

编列表单里的所有超链接：
HtmlElementCollection hc = this.webBrow.Document.Links;
            foreach (HtmlElement he in hc)
            {
                if (he.GetAttribute("href").Contains("OfficeDocBrower.aspx"))
                {
                    //he.SetAttribute("target", "");
                    //he.OuterHtml.Replace("target=_blank", "");
                }
    }

Answer 3

不要针对这段HTML,谁知道别的表单name属性是什么？我要能“遍历表单元素”的程序！

Answer 4

那就webClient GET HTML下来，检索<form></form>的位置

Answer 5

string type="",s="";
            HtmlDocument htm = this.webBrowser1.Document;
            HtmlElementCollection all = htm.All;
            for (int i = 0; i < all.Count; i++)
            {
                HtmlElement elem = all[i];
                if (elem.TagName.ToLower() == type)
                {
                   s=elem.GetAttribute("name").ToString();
                }
             } 
HtmlElementCollection htmlTabs = webBrowser1.Document.GetElementsByTagName("table");
            if(htmlTabs!=null&&htmlTabs.length>0)
            {
                HtmlElement htmlTable = htmlElements[0];
                HtmlElementCollection htmlRows = htmlElement.GetElementsByTagName("tr");
                HtmlElementCollection htmlCells = null;
                foreach (HtmlElement htmlRow in htmlRows)
                {
                        htmlCells = htmlRow.GetElementsByTagName("td");                 
                        foreach (HtmlElement htmlCell in htmlCells)
                        {
                            if (htmlCell.InnerText!=null)
                            {
                                strValue = htmlCell.InnerText.Trim();                
                                                     
                            }                        
                        }
                }
            }
递归遍历

Answer 6

完全是瞎扯，要需要用正则，我干嘛还要整DOM.

Answer 7

HtmlDocument doc = webBrowser1.Document;
            HtmlElementCollection forms= doc.Forms;
foreach (HtmlElement form in forms)
{
            foreach (HtmlElement element in form.All)
            {
                if (element.GetAttribute("type") == "hidden")
                {
                    Console.WriteLine(element.GetAttribute("name"));
                    Console.WriteLine(element.GetAttribute("value"));
                }
            }
}

Answer 8

strValue?哪儿来的, htmlElements哪来的?

Answer 9

 HtmlElementCollection elements = myWebBrowser.Document.All;
            foreach (HtmlElement element in elements)
            {
                if ("hidden" == element.GetAttribute("type"))
                {
                    string str = "name=" + element.GetAttribute("name")
                    + " value=" + element.GetAttribute("value");                    listBox1.Items.Add(str);
                }
            }
这段代码有什么问题？

Answer 10

foreach(HtmlElement element in form.All)
{
}
