使用python使用selenium webdriver通过xpath查找元素

我想用python将文件上传到onedrive上。但我找不到上传按钮。在驱动程序中找到xpath元素，但在编写代码时引发超时异常

HTML代码：

<div class="CommandBarItem beak-anchor command is-focused" data-bind="css: { 'is-toggled': isOpen() || isToggled(), 'is-disabled': isDisabled, 'is-disabled-invisible': isInvisibleWhenDisabled, 'is-open': isOpen, 'is-focused': focused, 'CommandBarItem--hasPayload': $component.hasPayload, 'icon-only': hasIconOnly, 'is-current-view': isCurrentView, 'is-pivot': isCurrentView !== null, 'is-last-pivot': isLastPivot }, class: commandClass() ? 'od-Command--' + commandClass() : '', hasFocus: isActive, raiseEventOnChange: { eventName: 'layoutChange', bubbleEvent: true, data: layoutChanged }, dismiss: { isOpen: isOpen, isAutomatic: payload &amp;&amp; payload.autoDismiss, timeout: payload &amp;&amp; payload.timeout, dismissOnResize: false, dismissOnScroll: false }, with: targetCommand(), attr: { tabindex: tabindex, role: role, 'aria-label': $parent.accessibleLabel, 'aria-haspopup': visibleChildren().length > 0 || !!payload, 'aria-selected': isOpen(), 'aria-pressed': isToggled(), 'data-automationid': automationId, 'aria-expanded': visibleChildren().length > 0 ? isOpen().toString() : false, id: newFeatureExperienceAnchor }, teachingBubble: teachingBubble, tooltip: { content: $data.tooltip, isTooltipDisabled: isOpen }" tabindex="0" role="menuitem" aria-label="Upload. Upload files from your computer to this location" aria-haspopup="true" data-automationid="" aria-expanded="false">
   <div class="CommandBarItem-linkWrapper">
      <div class="CommandBarItem-link" data-bind="measure: { measure: $parent.measurementReady, async: true }, click: onClick, automation: 'link'" data-automationid="link">
         <!--ko if: $parent.icon--><span class="CommandBarItem-icon" data-bind="component: { name: 'od-icon-glyph', params: { icon: $parent.icon, badge: $parent.iconBadge } }, attr: { 'is-flipped': $parent.positionIconRight }"><i class="od-IconGlyph ms-Icon ms-Icon--Upload css-46 od-IconGlyph--visible" data-bind="class: iconClasses, attr: { 'data-icon-name': icon }, css: { 'od-IconGlyph--badged': badge, 'od-IconGlyph--visible': icon }, with: badge" data-icon-name="Upload"></i></span><!--/ko--><!--ko if: $parent.iconUrl--><!--/ko--><!--ko if: $parent.label()--><span class="CommandBarItem-commandText" data-bind="text: $parent.label, attr: { 'is-flipped': $parent.positionIconRight, 'role': $parent.hasDynamicText ?

      <!--ko if: $data.inputType() === ActionInputType.htmlFileUpload--><!--/ko--><!--ko if: $data.inputType() === ActionInputType.folderUpload--><!--/ko-->
   </div>
   <!--ko if: children().length && isOpen() && !isClipped()--><!--/ko--><!--ko if: $component.hasPayload--><!--/ko-->
</div>

driver.implicitly_wait(30)
try:
 df = wait.until ( EC.presence_of_element_located ( (By.XPATH, '//*[@id="appRoot"]//div[@class="CommandBarItem beak-anchor command is-focused" and @aria-label="Upload. Upload files from your computer to this location"]')))
 df.click ()

但是它不起作用并抛出超时异常

有一种解决方法，您可以获取元素的位置，然后使用该位置单击该元素。或者您可以尝试使用javascript executer调用onclick方法。

如果您尝试自己调试，会发生什么？每个浏览器都应该有某种XPATH扩展，以查看您的查询是否匹配。当您有一个

等待时，为什么您是
驱动程序。隐式等待（30）
