如何使用Selenium WebDriver和Autohotkey获取HTML中的元素总数? [英] How to get the total number of elements in a HTML with Selenium WebDriver and Autohotkey?
问题描述
我试图通过给定的类获取HTML页面中的项目总数.我正在使用Selenium和Autohotkey
I am trying to get the total number of items in an HTML page by a given class. I am using Selenium and Autohotkey to do it
我已经搜索了很多这个主题，但是还没有找到自己的解决方案
I've searched a lot of this topic but haven't found my particular solution
我研究的大多数建议和答案都包含解决方案，但适用于Java或其他语言，不适用于Autohotkey(尽管在这种情况下它们具有相似的结构)
Most of suggestions and answers I researched included solutions but for Java or other language, not for Autohotkey (Although they have similar structures in this case)
使用此代码进行处理:
<html>
<body>
<div id="pancakes">
<button class="button">Blueberry</button><br><br>
<button class="button">Banana</button><br><br>
<button class="button">Strawberry</button><br><br>
<button class="button">Yumi</button><br><br>
</div>
</body>
</html>
要通过类从元素中获取文本，可以这样做:
For getting the text from a element by class it can be done by this:
driver.findElementByClass("button").Attribute("innerText")
输出:蓝莓
现在，要使用Xpath获取类的某个项，如下:
Now, for getting a certain item of a class using Xpath, is as follows:
driver.findElementsByXpath("//*[contains(@id,'pancakes')]/button").item[1].Attribute("innerText")
输出:草莓
我需要获取按钮"的总数.因此，我需要一个输出，该输出为我提供" 4 "(因为有 4个按钮" )
What I need is to get the total number of "buttons". So I need an output that gives me "4" (since there is 4 "buttons")
我还没有办法在Autohotkey中做到这一点.我见过针对其他语言的解决方案，例如
I havent find a way to do this in Autohotkey. I've seen solutions for other languages like
A
len(driver.find_elements_by_xpath('//a'))
B
WebElement webElement = driver.findElement(By.xpath("//form[@id='form1']/div[4]"));
//Get list of table elements using tagName
List<WebElement> list = webElement.findElements(By.tagName("table"));
C
IList<IWebElement> selectElements = driver.FindElements(By.TagName("select"));
foreach (IWebElement select in selectElements)
{
var selectElement = new SelectElement(select);
Console.WriteLine(selectElement.SelectedOption.Text);
}
更多，但由于这些函数和变量(例如len()，IList等)，这不适用于Autohokey
and more but this doesn't work with Autohokey because of those functions and variables (like len(), IList, and others)
我希望通过任何可能的方式获取仅项目总数
I am expecting to get just the total number of items by any way possible
我正在考虑尚未建立的Selenium的某些功能，我也不知道(例如某些-在行的末尾-".len"，.size"，.count"，但不是其中有为我工作的人)
I am thinking on maybe some function for Selenium I haven't founded yet and I dont know about (like some -at the end of the line- ".len",".size",".count" but non of them worked for me)
任何建议都值得欢迎和感谢，谢谢！
Any suggestions are welcome and appreciated, thanks!
哇，我只是错过了 .Count "
这就是我想要的
driver.findElementsByXpath("//*[contains(@id,'pancakes')]/button").Count()
感谢化脓
推荐答案
您可以使用 Count()方法获取与xpath匹配的元素数.
You can use Count() method to get the number of elements matching your xpath.
driver.findElementsByXpath("//*[contains(@id,'pancakes')]/button").Count()
您可以参考以获取更多信息.
you can refer to this for more information.
