Selenium元素定位--Xpath

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div id="A">
    <div id="B">
        <div>parent to child</div>
    </div>
</div>
</body>
</html>

1、通过开发者工具直接copy 2、串联的方式定位元素；

from selenium import webdriver
from time import sleep

'''
串联查找的方式
'''

driver = webdriver.Chrome()
driver.get('E:\XueXi\ZDH\DaiMa\DaiMa\CZBK\one\myhtml2.html')

mytext = driver.find_element_by_id('B').find_element_by_tag_name('div').text
print(mytext)
sleep(3)
driver.quit()

3、通过父元素定位子元素；

from selenium import webdriver
from time import sleep

'''
通过父元素定位子元素
'''

driver = webdriver.Chrome()
driver.get('E:\XueXi\ZDH\DaiMa\DaiMa\CZBK\one\myhtml2.html')

mytext = driver.find_element_by_xpath("//div[@id='B']/div").text
print(mytext)
driver.quit()

from selenium import webdriver
from time import sleep

'''
通过父元素定位子元素,xpath轴
'''

driver = webdriver.Chrome()
driver.get('E:\XueXi\ZDH\DaiMa\DaiMa\CZBK\one\myhtml2.html')

mytext = driver.find_element_by_xpath("//div[@id='B']/child::div").text
print(mytext)
driver.quit()

4、通过子元素定位父元素；

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div id="A">
    <!--子节点定位父节点-->
    <div>
        <div>child to parent
            <div>
                <div id="C"></div>
            </div>
        </div>
    </div>
</div>
</body>
</html>

from selenium import webdriver

# "由子节点定位父节点"

driver = webdriver.Chrome()
driver.get('E:\XueXi\ZDH\DaiMa\DaiMa\CZBK\one\myhtml3.html')

# 1.xpath: `.`代表当前节点; '..'代表父节点
mytext = driver.find_element_by_xpath("//div[@id='C']/../..").text
print(mytext)

# 2.xpath轴 parent
mytext1 = driver.find_element_by_xpath("//div[@id='C']/parent::div/parent::div").text
print(mytext1)

driver.quit()

5、通过弟弟节点定位哥哥节点元素；

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
        <!--下面两个节点用于兄弟节点定位-->
    <div>brother 1</div>
    <div id="D"></div>
    <div>brother 2</div>
</body>
</html>

from selenium import webdriver

"""
通过弟弟定位哥哥
"""

driver = webdriver.Chrome()
driver.get('E:\XueXi\ZDH\DaiMa\DaiMa\CZBK\one\myhtml4.html')

# 1.xpath,通过父节点获取其哥哥节点
mytext = driver.find_element_by_xpath("//div[@id='D']/../div[1]").text
print(mytext)

# 2.xpath轴 preceding-sibling
mytext1 = driver.find_element_by_xpath("//div[@id='D']/preceding-sibling::div[1]").text
print(mytext1)

driver.quit()

6、通过哥哥节点定位弟弟节点元素：

from selenium import webdriver

"""
哥哥定位弟弟示例
"""

driver = webdriver.Chrome()
driver.get('E:\XueXi\ZDH\DaiMa\DaiMa\CZBK\one\myhtml4.html')

# 1.xpath，通过父节点获取其弟弟节点
mytext = driver.find_element_by_xpath("//div[@id='D']/../div[3]").text
print(mytext)

# 2.xpath轴 following-sibling
mytext1 = driver.find_element_by_xpath("//div[@id='D']/following-sibling::div[1]").text
print(mytext1)

driver.quit()
