Java selenium 使用 xpath 查找元素 [英] Java selenium find element with xpath

问题描述

我正在开发一个网络应用程序，我需要找到一个特定的元素，但我无法用我的 xpath 找到它.这是我试图找到元素的 html 代码

<tr><th class="详细信息"><label>名称</label></th><td class="数据"><div id="..."><div id="..."></div><input id="..." type="text">
</td></tr>.....

我成功找到了它，但是当我注意到 ID 是自动生成的时，我被卡住了.我试图解决这个问题，找到包含文本名称"的标签，然后找到兄弟姐妹但什么也没有.这是我的 xpath:

//*[text()[contains(.,'Name')]]/../following-sibling::td

解决方案

你应该尝试使用下面的 xpath :-

String xpath = "(.//label[text() = 'Name']/following::input)[1]";

或

String xpath = ".//label[text() = 'Name']/../following-sibling::td//input";

或

String xpath = "(.//input[preceding::label[text() = 'Name'])[1]";

或

String xpath = ".//input[ancestor::td[preceding-sibling::th/label[text() = 'Name']]]";

您可以使用上述 xpath 中的任何一个来查找所需的输入元素，如下所示:-

browser.findElement(By.xpath(xpath));

all I'm delevoping a web app and I need to find a specific element but I can't find it out with my xpath. This is the html code where I'm trying to find the element

<table>
    <tr>
        <th class="details">
            <label>Name</label>
        </th>
        <td class="data">
            <div id="...">
                <div id="..."></div>
                <input id="..." type="text">
            </div>
        </td>
    </tr>
 ..........
</table>

I successfully found it but when I noticed that the ids are autogenerated I got stuck. I tried to solve this problem finding the label which contains the text 'Name' and then finding the siblings but nothing. This is my xpath:

//*[text()[contains(.,'Name')]]/../following-sibling::td

解决方案

You should try using below xpath :-

String xpath = "(.//label[text() = 'Name']/following::input)[1]";

Or

String xpath = ".//label[text() = 'Name']/../following-sibling::td//input";

Or

String xpath = "(.//input[preceding::label[text() = 'Name'])[1]";

Or

String xpath = ".//input[ancestor::td[preceding-sibling::th/label[text() = 'Name']]]";

You can use anyone of these above xpath to find desire input element as below :-

browser.findElement(By.xpath(xpath));
