Question

私はxpathの問題に苦しんでいます。コードが処理されているiframe内に含まれています

webElement = Driver.FindElement(By.XPath("//*[contains(text(),'AAA1 Output')]//preceding::label/input[@class='ng-untouched ng-pristine ng-valid'][@type='checkbox']")); 

webElement = Driver.FindElement(By.XPath("//*[.,'AAA1 Output')]//preceding::label/input[@class='ng-untouched ng-pristine ng-valid'][@type='checkbox']")); 

webElement = Driver.FindElement(By.XPath("//*[contains(text(),'AAA1 Output')]//preceding::input[@class='ng-untouched ng-pristine ng-valid'][@type='checkbox']")); 

webElement = Driver.FindElement(By.XPath("//*[.,'AAA1 Output')]//preceding::input[@class='ng-untouched ng-pristine ng-valid'][@type='checkbox']")); 

webElement = Driver.Instance.FindElement(By.XPath("//div[@class='panel panel-info']//following::tr[contains(., 'AAA1 Output')]/td[1]")); 

webElement = Driver.Instance.FindElement(By.XPath("//[contains(.,'ABC Output']//following::tr[contains(., 'AAA1 Output')]/td[1]")); 

：私はチェックボックスをクリックして、リスト内の最初の行を見つけようとしている

<div _ngcontent-c10 class="panel panel-info"> 
    <div _ngcontent-c10 class="panel-heading"> ABC Output </div> 
<div _ngcontent-c10 class="panel-body"> 
<form _ngcontent-c10 novalidate class="ng-untouched ng-pristine ng-valid"> 
<div _ngcontent-c10 class="row"> 
<table _ngcontent-c10 class="table tb-striped"> 
<tbody _ngcontent-c10> 
<tr _ngcontent-c10=""> 
      <td _ngcontent-c10="" class="td-fixed-width-35"> 
      <label _ngcontent-c10=""> 
       <input _ngcontent-c10="" type="checkbox" value="" class="ng-untouched ng-pristine ng-valid"> 
      </label> 
     </td> 
     <td _ngcontent-c10="" class="td-fixed-width-20 no-side-padding"> 
      <img _ngcontent-c10="" class="outputLogo" src="https://qa-server/Services/content/logos/AAAA1.png" alt="AAA1"> 
     </td> 
     <td _ngcontent-c10="" class="td-text-bold"> 
      AAA1 Output 
      <!----> 
     </td> 
</tr> 
<tr _ngcontent-c10=""> 
      <td _ngcontent-c10="" class="td-fixed-width-35"> 
      <label _ngcontent-c10=""> 
       <input _ngcontent-c10="" type="checkbox" value="" class="ng-untouched ng-pristine ng-valid"> 
      </label> 
     </td> 
     <td _ngcontent-c10="" class="td-fixed-width-20 no-side-padding"> 
      <img _ngcontent-c10="" class="outputLogo" src="https://qa-server/Services/content/logos/BBB1.png" alt="BBB1"> 
     </td> 
     <td _ngcontent-c10="" class="td-text-bold"> 
      BBB1 Output 
      <!----> 
     </td> 
</tr> 
<tr _ngcontent-c10=""> 
      <td _ngcontent-c10="" class="td-fixed-width-35"> 
      <label _ngcontent-c10=""> 
       <input _ngcontent-c10="" type="checkbox" value="" class="ng-untouched ng-pristine ng-valid"> 
      </label> 
     </td> 
     <td _ngcontent-c10="" class="td-fixed-width-20 no-side-padding"> 
      <img _ngcontent-c10="" class="outputLogo" src="https://qa-server/Services/content/logos/CCC1.png" alt="CCC1"> 
     </td> 
     <td _ngcontent-c10="" class="td-text-bold"> 
      CCC1 Output 
      <!----> 
     </td> 
</tr> 

、これらは、私はすでに試したものです

しかし、最初の要素のチェックボックスをクリックすることはできません。
