Selenium：如何使用FindElementByXPath来识别元素

Question

我需要单击导出器。

这是html代码，

<div class="ui-dialog-buttonset">
  <button type="button" title="" style="" class="call-to-action ui-button ui-corner-all ui-widget button-default">Exportar</button>
  <button type="button" title="" class="ui-button ui-corner-all ui-widget button-cancel">Cancelar</button>
</div>

Answer 1

要定位文本为 Exportar 的元素，您可以使用以下任一定位器策略：

• < p>css_selector：

  div.ui-dialog-buttonset > Button.call-to-action.ui-button.ui-corner-all.ui-widget.button-default
  

• xpath：

  //button[@class='call-to-action ui-button ui-corner-all ui-widget button-default' and text()='Exportar']
  

Answer 2

试试这个：

driver.find_element_by_xpath('//button[@class="call-to-action ui-button ui-corner-all ui-widget button-default"]').click()
