Selenium/Python:如何获取一个类中与另一个类处于同一级别的按钮的所有实例？

Question

在此特定页面上，出现了两个span class=“频道名称”。在同一级别上的每个span类下，都有多个div class=“contract ng scope ng隔离作用域ui draggable ui draggablehandle”的实例。在每一个下，我试图检索所有按钮类文本（即B），HTML代码提取的最后一行。

HTML代码：

<span class="channel-name">
<div class="contract ng-scope ng-isolate-scope ui-draggable ui-draggable-handle" ng-repeat="contract in data.channel.contracts track by $index" drag-data="contract" mit-draggable="">
  <div class="ng-isolate-scope ui-droppable" ng-class="{'invisible': atMaxContractsPerChannel(data.channel)}" drop-success="addToContractTop" drop-data="{verticalSeq: $index, contract: contract, priority: data.priority}" mit-droppable="">
    <div class="drop-zone-placeholder"></div>
    <mit-contract class="ng-isolate-scope" data="{verticalSeq: $index, contract: contract, channel: data.channel, currentProgram: data.currentProgram, programBackup: data.programBackup}">
      <div class="ibox-content no-margins " tooltip-placement="top" tooltip-class="beacon-body-uib-tooltip" tooltip-append-to-body="true" uib-tooltip-template="ui.views.infoTooltip" tooltip-is-open="errorAndHovering" tooltip-trigger="none" mit-err="{errs:[{event:'contract_0-0', context:'validateProgram'}], errClass:'mit-err-right-border'}">
        <button class="name btn-link ng-binding ng-isolate-scope" tooltip-class="beacon-body-uib-tooltip" tooltip-placement="left" tooltip-append-to-body="true" uib-tooltip="Edit" ng-disabled="disableEdit()" mit-mini-modal="" ng-click="editContract(contract)">B</button>

这是我的python代码。它现在所做的就是检查列名，以确保它搜索的是正确的频道名称，如果是这样的话，检索它下面的第一个按钮名称并返回它，我知道我用的是错误的方式，任何帮助都将不胜感激！

def get_contract_name_in_inuring_column(self, column_name):
        elements = self.page_loc.find_elements_by_xpath("//span[@class='channel-name']")
        count = 0
        for element in elements:
            if element.find_elements_by_xpath(".//input[@name='name']")[0].get_attribute('value') == column_name:
                return self.page_loc.presence_of_all_css('button[ng-click="editContract(contract)"]')[count].text
            count += 1

为了检索第一个和第二个按钮，下面是XPath。

(.//button[@class='name btn-link ng-binding ng-isolate-scope'][@tooltip-class='beacon-body-uib-tooltip'])[1] 
(.//button[@class='name btn-link ng-binding ng-isolate-scope'][@tooltip-class='beacon-body-uib-tooltip'])[2]
