Selenium和Python中的XPATH问题

Question

我正在尝试自动化一些服务组件--现在。我正在做的大多数事情都是工作的，除了下面的例外。

从网站上获取下面的代码片段。

    <select aria-required="true" 
                    aria-labelledby="label.cmdb_ci_netgear.u_criticality"
                    ng-non-bindable="true" name="cmdb_ci_netgear.u_criticality" 
                    id="cmdb_ci_netgear.u_criticality" 
                    onchange="onChange('cmdb_ci_netgear.u_criticality');" style="; " 
                    class="form-control" mandatory="true" aria-readonly="false">
        <option value="" role="option">-- None --</option>
        <option value="Level_1" role="option">Level 1</option>
        <option value="Level_2" role="option">Level 2</option>
        <option value="Level_3" role="option">Level 3</option>
        <option value="Level_4" role="option">Level 4</option>
        <option value="Level_5" role="option">Level 5</option>
        <option value="Level_6" role="option">Level 6</option>
        <option value="0" role="option">0</option>
        <option value="Not_Agreed" role="option">Not Agreed</option>
        <option value="level 1" role="option">level 1</option>
        <option value="1" role="option">1</option>
        <option value="3843" role="option">3843</option>
    </select>

如果我检查超文本标记语言并复制Level_(1-6)选项的XPATH，我会得到下面的关系。

    code =      <option value="Level_1" role="option">Level 1</option>
    xpath =     //*[@id="cmdb_ci_netgear.u_criticality"]/option[2]      

    code =      <option value="Level_2" role="option">Level 2</option>
    xpath =     //*[@id="cmdb_ci_netgear.u_criticality"]/option[3]          

    code =      <option value="Level_3" role="option">Level 3</option>
    xpath =     //*[@id="cmdb_ci_netgear.u_criticality"]/option[4]          

    code =      <option value="Level_4" role="option">Level 4</option>
    xpath =     //*[@id="cmdb_ci_netgear.u_criticality"]/option[5]          

    code =      <option value="Level_5" role="option">Level 5</option>
    xpath =     //*[@id="cmdb_ci_netgear.u_criticality"]/option[6]          

    code =      <option value="Level_6" role="option">Level 6</option>
    xpath =     //*[@id="cmdb_ci_netgear.u_criticality"]/option[7]      

这是我运行的代码，用来匹配来自其他地方的存储值，以更新相应的XPath

def CI_Create(self,ci_id,Catols):
    self.CI_field_excludes = ['install_status','u_visible_to', 'discovery_source','device_type','u_environment']
    self.ci_ids = ci_id
    self.Catol = Catols
    self.browser.get("https://rttmstest.service-now.com/cmdb_ci_netgear.do")
    sleep(5)
    for i in self.Catol:
        sleep(5)
        print('processing '+ i)
        if i == 'u_criticality':
            print('criticality text is ' + self.Catol['u_criticality'][1])
            if self.Catol[i][1] == 'Level_1':
                print('xxx - process criticality as Level_1')
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.u_criticality"]/option[2]').click()
            elif self.Catol[i][1] == 'Level_2':
                print('xxx - process criticality as Level_2')
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.u_criticality"]/option[3]').click()
            elif self.Catol[i][1] == 'Level_3':
                print('xxx - process criticality as Level_3')
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.u_criticality"]/option[4]').click()
            elif self.Catol[i][1] == 'Level_4':
                print('xxx - process criticality as Level_4')
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.u_criticality"]/option[5]').click()
            elif self.Catol[i][1] == 'Level_5':
                print('xxx - process criticality as Level_5')
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.u_criticality"]/option[6]').click()
            elif self.Catol[i][1] == 'Level_6':
                print('xxx - process criticality as Level_6')
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.u_criticality"]/option[7]').click()
            else:
                print('CRITICAL Failure to select criticality')
        if i in self.CI_field_excludes:
            print('excluding '+i)
            if i == 'discovery_source':
                print('processing lower '+i)
                self.browser.find_element_by_xpath('//*[@id="cmdb_ci_netgear.discovery_source"]/option[3]').click()
            else:
                continue
        else:
            print('processed under else '+i)
            self.browser.find_element_by_xpath(self.Catol[i][0]).send_keys(self.Catol[i][1])
    # self.browser.find_element_by_xpath(device_save_modification).click()
    sleep(5)
    return

所有的指纹和睡眠都是我试图获得理智，为什么选择是关闭的。下面是self.catol调用的精简版本

    CMDB_CAT = {'name': ['//*[@id="cmdb_ci_netgear.name"]', 'somename'],
    'u_managed_b': ['//*[@id="sys_display.cmdb_ci_netgear.u_managed_by"]', 'IT'],
    'u_common_name' : ['//*[@id="cmdb_ci_netgear.u_common_name"]', 'somecommonname'],
    'u_visible_to' : ['//*[@id="cmdb_ci_netgear.u_visible_to"]', 'IT'],
    'install_status' : ['//*[@id="cmdb_ci_netgear.install_status"]', 'Active'],
    'u_criticality' : ['//*[@id="cmdb_ci_netgear.u_criticality"]', 'Level_3'],
    }

如果u_criticality为“Level_3”，则应设置'//*@id="cmdb_ci_netgear.u_criticality"/option4'.

一切都表明这正在发生，除了字段显示“4级”作为选择。

感谢任何人的帮助。

您可以使用selenium select类来选择项目并以well.Please的形式获取文本值。如果有此帮助，请按照options.See进行检查。

from selenium.webdriver.support.ui import Select
select=Select(driver.find_element_by_id('cmdb_ci_netgear.u_criticality'))
select.select_by_index(3) # First item of the select index is always 0
print(select.first_selected_option.text)

或

select=Select(driver.find_element_by_id('cmdb_ci_netgear.u_criticality'))
select.select_by_value("Level_3")
print(select.first_selected_option.text)

或

element = driver.find_element_by_xpath("//select[@id='cmdb_ci_netgear.u_criticality']")
all_options = element.find_elements_by_tag_name("option")
for option in all_options:
    print("Value is: %s" % option.get_attribute("value"))
    option.click()
