从 Xpath 访问文本

Question

我在返回通过 xpath 找到的文本时遇到问题。首先我需要通过css选择器找到元素：

ticker1 = browser.find_element_by_css_selector('[data-id="1"]')
print(ticker1.get_attribute('innerHTML'))

<div class="header_card"><div class="header_card_title">Day's Title<i class="fa fa-info-circle 
toolTrigger" data-title="Day's Title" data- 
id="DaysTitle-tooltip" data-model="what-is-this"></i></div><div 
class="header_card_trend_symbol headerTrend" data-title="" data-id="1" data-process="" 
data-categories="" data-datapoints=""><i class="fa fa-arrow-circle-o-down ph_trend_red"></i></div> 
<div class="header_card_metric_value" data-id="1"><span>$0</span></div></div><div 
class="header_bars_container"><a href="#" class="dropdown-toggle" data-toggle="dropdown" 
data-boundary="viewport" role="button" aria-haspopup="true" aria-expanded="false"><i class="fa fa- 
bars optionsIconDropDown"></i></a><ul class="dropdown-menu drop-sm" style="position: relative; right: 
10px; top: -16px !important; "><li></li><li><a href="#" class="headerTrend" data-title="Prior Day's 
Production" data-id="1" data-open="" data-process="" data-categories="" data-datapoints="">Trend</a> 
</li></ul></div>

然后我通过 xpath 访问子元素

t1l = ticker1.find_element_by_xpath(".//div[@class='header_card_title']")
print(t1l.get_attribute('innerHTML'))

Day's Title<i class="fa fa-info-circle toolTrigger" data-title="Day's Title" 
data-id="PriorDaysProduction-tooltip" data-model="what-is-this"></i>

我试过.text，get_attribute('text')，get_attribute('values')都返回''

Answer 1

想通了

它是get_attribute('innerText')，虽然不知道为什么。

Answer 2

你离得很近。您需要提取 text 属性，而不是 get_attribute('innerHTML')，如下所示：

t1l = ticker1.find_element_by_xpath(".//div[@class='header_card_title']")
print(t1l.text)

理想情况下，要打印文本Day's Title，您必须为visibility_of_element_located() 诱导WebDriverWait，您可以使用以下Locator Strategies 之一：

print(WebDriverWait(ticker1, 20).until(EC.visibility_of_element_located((By.XPATH, ".//div[@class='header_card_title']"))).text)

您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
