Question

我在搜索innerHTML元素时遇到了一些麻烦。编辑:(我的意思是从innerHTML中搜索元素。）

目标：查找变量内部的ID

我的英语不好，我希望大家都明白。

//All css elements
var itemHolder = WebDriver.FindElementsByClassName("itemHolder");
//Get singleElement from itemHolder
foreach (var element in itemHolder)
{
    //i think that easy to understand
    if (!element.GetAttribute("style").Equals("display: none;"))
    {
        var innerHtml = element.GetAttribute("innerHTML");
        //simply regex for find the right one element
        string reg = @"(item app730 context2)";
        bool command = Regex.IsMatch(innerHtml, reg, RegexOptions.IgnoreCase);
        if (command)
        {
            Console.WriteLine(element.GetAttribute("innerHTML"));
            var inner = element.GetAttribute("innerHTML");
            //inner = <div style='border - color: rgb(210, 210, 210); z - index: 3; position: relative; ' class='item app730 context2' id='item730_2_3294048593'></div>

           //now i need id from inner, how can i do it?
           //first variant: Regex inner, found item730_2_3294048593, that is a hard way i find. im bad in regex
           //Regex Example: strike = Regex.Match(inner, "(id=')[a-zA-Z_0-9]{20}").ToString();

           //second and i think bether variant but do not have a plan how to start: P
           // 1. convert inner to html elements
           // 2. search id
           //var found = Regex.Match(inner, "");

            break;
        }

    }
}

我希望有人可以帮助我，非常感谢！问候Ivorysmoker

Answer 1

我假设您有这样的HTML布局：

<div id="outer">
    <div id="inner">
        hello
    </div>
</div>

如果是这种情况，您可以使用IWebElement的{{1}}方法查找子元素：

FindElement

请注意，XPath for inner在开头有一个句点，表示任何结果必须是我们搜索的元素的子元素。

从那里你可以IWebElement outer = FindElement(By.XPath("//*[@id='outer']")); IWebElement inner = outer.FindElement(By.XPath("./div"));来获取你的身份。

Answer 2

扩展Ben Chand的答案。请原谅这个伪代码：

IWebElement outer = By.XPath("//*[@class='itemHolder']");
....
public By getInnerByIndex(int index) {
    By inner = By.XPath(".//div[@id='innerHtml'][" + index + "]");
    By innerLocator = new ByChained(outer, inner);
    return innerLocator;
}

Answer 3

我从innerHTML获取ID的方法。（动态内容）

 var strike = Regex.Match(inner, "(id=')[a-zA-Z_0-9]{20}");
                    result = strike.ToString().Replace("id='", "");

Regex Out：id ='item730_2_3294048593 Regex Out替换：item730_2_3294048593

感谢所有答案！
