Robot Framwork - SeleniumLibrary基于Python3元素里面查找元素,文字,属性

参考地址:https://blog.csdn.net/max229max/article/details/82852155

Robot Framwork中Selenium2Library已升级到SeleniumLibrary同样没有提供在通过get webelement获得已有元素列表中查找元素的方法,比如在用户列表框中通过勋章属性确定用户类别,并获取用户名

查找了很多资料只有一个类似的需求参考,Selenium2Library的版本.python升级SeleniumLibrary很多用法不一样,参考代码运行不通.自己研究了一番参考源码,找到两种解决方案:

①在D:\Program Files\Python36\Lib\site-packages\SeleniumLibrary\keywords\element.py源码中参考get_webelement添加两个函数传入parent即可通过父元素查找子元素

class ElementKeywords(LibraryComponent):

# 从父元素中查找子元素文字信息

    @keyword(name='Get Text In Element')

def get_text_in_element(self, element, locator):

"""

        :paramelement:

        :paramlocator:

        :return:

Example:

| ${text}= | `Get Text In Element` | element | locator(xpath=.//div[@class="break"]) |

"""

        return self.find_element(locator,parent=element).text

# 从父元素获取属性值

    @keyword(name='Get Attribute In Element')

def get_attribute_in_element(self, element, locator, attribute):

"""Returns the value of ``attribute`` from the element ``locator``.

See the `Locating elements` section for details about the locator

syntax.

Example:

| ${id}= | `Get Element Attribute` | css:h1 | id |

"""

        return self.find_element(locator,parent=element).get_attribute(attribute)

@keyword(name='Get WebElement')

def get_webelement(self, locator):

"""Returns the first WebElement matching the given ``locator``.

See the `Locating elements` section for details about the locator

syntax.

"""

        return self.find_element(locator)

②参考源码自己编写工具包

图片如下

from selenium.webdriver.remote.webelementimport WebElement

from SeleniumLibrary.locatorsimport ElementFinder

import SeleniumLibrary

try:

str()# attempt to evaluate basestring

    def isstr(s):

return isinstance(s, str)

except NameError:

def isstr(s):

return isinstance(s, str)

class ElementUtil(SeleniumLibrary.SeleniumLibrary):

def finder(self):

driver = ElementFinder(self)

return driver

# 通过元素查找元素获取文本值

def get_text_in_ele(element, locator):

"""Returns the first child WebElement matching the given locator in given parent WebElement.

element: should be an parent element

locator: should be an child locator string

See `introduction` for details about locating elements.

Examples:

| ${element} | Get Text In Element | parent element | child locator |

"""

    return _element_find_in_element(element, locator, True, True).text

# Python3中获取属性方式,通过元素查找元素获取属性值

def get_element_attribute_in_element(element, locator, attribute_name):

"""Returns the value of ``attribute`` from the element ``locator``.

See the `Locating elements` section for details about the locator

syntax.

Example:

| ${id}= | `Get Element Attribute In Element` | parent | css:h1 | id |

Passing attribute name as part of the ``locator`` was removed

in SeleniumLibrary 3.2. The explicit ``attribute`` argument

should be used instead.

"""

    # ek = ElementKeywords()

    #升级Python3后locator和属性名需单独传入

    # locator, attribute_name = ek.parse_attribute_locator(attribute_locator)

# locator, attribute_name = ElementFinder(self)._parse_locator(attribute_locator)

# print(locator,attribute_name)

    element = _element_find_in_element(element, locator, True, False)

if elementis None:

raise ValueError("Element '%s' not found." % (locator))

return element.get_attribute(attribute_name)

# 私有方法元素查找元素,继承SeleniumLibrary.SeleniumLibrary创建元素查找实例ElementFinder

def _element_find_in_element(element, locator, first_only, required, tag=None):

print(type(element))

if isinstance(element, WebElement):

browser = element

if isstr(locator):

try:

driver = ElementUtil().finder()

elements = driver.find(locator, tag=tag, first_only=first_only, required=required, parent=browser)

return elements

except:

pass

两种方案都运行成功了
