使用 find_element_by_xpath 查找元素

Question

我试图通过 xpath 查找元素，但它 return 什么也没有。似乎所有 find_elements 方法都有效，除了 xpath。我正在尝试查找可点击的文本 Ponderosa Campground。

def searchCondition():
elem = driver.find_elements_by_xpath("//div[@aria-label='PONDEROSA CAMPGROUND']")
elem.click()

这里是 URL 我试图找到元素的地方。 https://www.recreation.gov/search?q=Ponderosa%20Campground

<div data-component="FocusManager" tabindex="-1" style="outline: none;">
<div class="flex-grid search-outer-wrap" data-component="FlexRow">
<div class="flex-col-12" data-component="FlexCol">
<div class="rec-flex-card-wrap " id="rec-card-233118_campground">
<a data-card="true" class="rec-flex-card-image-wrap" href="/camping/campgrounds/233118" target="_blank" rel="noopener noreferrer" alt="PONDEROSA CAMPGROUND">
<div data-component="FauxImage" class="sarsa-faux-image rec-flex-card-image-wrap-faux-image" role="img" aria-label="PONDEROSA CAMPGROUND" style="min-height: 155px; background-image: url(&quot;https://cdn.recreation.gov/public/images/76799.jpg&quot;);"></div></a>
<div class="rec-flex-card-content-wrap"><a href="/camping/campgrounds/233118" target="_blank" rel="noopener noreferrer" aria-label="PONDEROSA CAMPGROUND - 2.6 stars /    / night">

这是完整的脚本。

    if elem.isDisplayed():
        print(elem)
        elem.click()
    else:
        print("no availability")
        searchCondition()

    time.sleep(20)

Answer 1

您必须将 xpath 指向交互元素，例如 a、input、button 并且必须在预期条件下引发一些明确的等待，以检查元素是否已全部设置为执行点击操作。例如-

WebDriverWait(web, 20).until(EC.element_to_be_clickable((By.XPATH,"//a[@alt='PONDEROSA CAMPGROUND']")))

elem = web.find_element_by_xpath("//a[@alt='PONDEROSA CAMPGROUND']")

elem.click()

点击图片后会打开如下新标签页。看到这个操作在点击操作后添加一些wait sometime -

使用 find_element_by_xpath 查找元素
