在python selenium中使用父/同级查找元素

Question

我正在使用python中的selenium来清理一个使用angular js设计的web页面，因此没有健壮的元素标识符，如id等。我完全依赖于css选择器（是动态的）和XPath。

我有以下代码-

<div class="dpm-form-row ng-star-inserted">
<dpm-input-number class="flex-6">
<dpm-input-label>
<label>Fixed Rate</label>
</dpm-input-label>
<dpm-input-number-bare>
<input size="1" type="text" placeholder="" class="ng-pristine ng-valid ng-touched">
</dpm-input-number-bare>
</dpm-input-number>
<div class="flex-6">
</div>
</div>

它基本上是一个名为“固定比率”的标签，后面跟着一个输入文本框。 我正想抢的就是那个盒子。

我已经设法使用以下代码获取标签，我在使用父/兄弟逻辑获取框时遇到了麻烦-

element = driver.find_element_by_xpath('//*[contains(text(),"Fixed Rate")]')

Answer 1

从你前面的问题转贴。 原始解决方案:

//input[@class="ng-pristine ng-valid ng-touched"][../preceding-sibling::dpm-input-label[1]/label[.="Fixed Rate"]]

3使用follow-sibling轴的XPath:

//dpm-input-label[label[.="Fixed Rate"]]/following-sibling::dpm-input-number-bare[1]/input
//dpm-input-label[label[contains(.,"Fixed Rate")]]/following-sibling::dpm-input-number-bare[1]/input
//dpm-input-label[contains(.,"Fixed Rate")]/following-sibling::dpm-input-number-bare[1]/input

3 XPath使用preceding-sibling轴和多个包含输入元素的:

//input[contains(@class,"ng-pristine") and contains(@class,"ng-valid") and contains(@class,"ng-touched")][../preceding-sibling::dpm-input-label[1]/label[.="Fixed Rate"]]
//input[contains(@class,"ng-pristine") and contains(@class,"ng-valid") and contains(@class,"ng-touched")][../preceding-sibling::dpm-input-label[1]/label[contains(.,"Fixed Rate")]]
//input[contains(@class,"ng-pristine") and contains(@class,"ng-valid") and contains(@class,"ng-touched")][../preceding-sibling::dpm-input-label[1][contains(.,"Fixed Rate")]]

4使用前轴的XPath:

//input[@class="ng-pristine ng-valid ng-touched"][preceding::label[1][.="Fixed Rate"]]
//input[@class="ng-pristine ng-valid ng-touched"][preceding::label[1][contains(.,"Fixed Rate")]]
//input[contains(@class,"ng-pristine") and contains(@class,"ng-valid") and contains(@class,"ng-touched")][preceding::label[1][.="Fixed Rate"]]
//input[contains(@class,"ng-pristine") and contains(@class,"ng-valid") and contains(@class,"ng-touched")][preceding::label[1][contains(.,"Fixed Rate")]]
