使用C＃用于XPATH的目标是什么？

Question

目标：当我单击按钮时，它应该转到我想要的站点，然后在文本框中输入文本=“ test”（id =“ 1648750690212editingInput”）。

我能够用Chrome中的硒扩展来完成它，但是目标是XPATH：iDrelative，看起来像xpath = // table [@id ='gridlist_headers']]/thead/thead/tr [2]/td [2 ]/div/div [2]/跨度/输入。

问题：如何格式化C＃中的XPATH来实现这一目标？

html ＆lt; input type =“ text” class =“ ui-igedit输入ui-igedit-placephorder ui-iggrid-filterereditor” label =“ text Editor”样式=“高度：100％; text-align：left;”＆gt;

c＃

        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://fakesite.com");
            driver.FindElement(By.XPath("//table[@id='gridList_headers']/thead/tr[2]/td[2]/div/div[2]/span/input")).SendKeys("test");
        }```

Answer 1

通常输入字段使用发布请求
因此，您可以将文本带有get request并将其发布回到服务器中的

简单请求请求

using System.Net;

...

using (var wb = new WebClient())
{
    var response = wb.DownloadString(url);
}

简单的

using System.Net;
using System.Collections.Specialized;

...

using (var wb = new WebClient())
{
    var data = new NameValueCollection();
    data["username"] = "myUser";
    data["password"] = "myPassword";

    var response = wb.UploadValues(url, "POST", data);
    string responseInString = Encoding.UTF8.GetString(response);
}

帖子请求，正如您在XPATH上所要求的，您可以将其与Regex一起使用，它将为您提供在HTML文件上的强大搜索

{
// first use regex to get a part of html
// the (.*) matches every character between the two strings
// you get its value by using ".Groups(1).Value;"       
var tagsac = Regex.Match(page_Source_Str, Regex.Escape("<div class=\"video-metadata video-tags-list ordered-label-list cropped\"><ul>") + "(.*)" + Regex.Escape("</ul></div>")).Groups(1).Value;

// now you add the tag back to use xpath       
var tags = "<div class=\"video-metadata video-tags-list ordered-label-list cropped\"><ul>" + tagsac + "</ul></div>";
    
// now using xpath
var xml = XElement.Load(new System.IO.StringReader((tags)));
// you dig down elements to what you want    
var k = xml.<ul>.<li>.ToList;

// you get the html element value or attribute value like so    
var Tag_List = k.FindAll(c => (XElement)c.<a>.Attributes.FirstOrDefault.Value.StartsWith("/tags")).Select(xc => xc.<a>.FirstOrDefault.Value.ToLower.Replace("-", " ")).ToList;
    }
