Question

在某些情况下，某些列可能会丢失，因此我们为获取表数据而创建的XPath将获取不正确的数据。

例如：如果我需要获取总收入，那么Xpth将是

.//*[@id='sessionForm:dataTable_data']/tr/td[7]/div

但假设在＆＃34; Total Revenue＆＃34;之前有一列？字段丢失，然后XPath将更改为.//*[@id='sessionForm:dataTable_data']/tr/td[6]/div但在我的脚本中，它将为我提供错误列的值。

表格后面的HTML如下所示：

<div class="ui-datatable-scrollable-body" tabindex="-1" style="margin-right: 0px; width: 680px;">
 <table role="grid">
   <thead class="ui-datatable-scrollable-theadclone" style="height: 0px;">
     <tr role="row">
      <th id="sessionForm:dataTable:userid_clone" class="ui-state-default ui-sortable-column" style="width:58px" aria-label="User Id: activate to sort column ascending" role="columnheader" tabindex="0" aria-sort="other">
        <span class="ui-column-title">User Id</span>
      </th>
      <th id="sessionForm:dataTable:Enterprisename_clone" class="ui-state-default ui-sortable-column" style="width:70px" aria-label="Enterprise: activate to sort column ascending" role="columnheader" tabindex="0" aria-sort="other">
        <span class="ui-column-title">Enterprise</span>
      </th>
      <th id="sessionForm:dataTable:startTime_clone" class="ui-state-default ui-sortable-column" style="width:56px" aria-label="Start Time: activate to sort column ascending" role="columnheader" tabindex="0" aria-sort="other">
        <span class="ui-column-title">Start Time</span>
      </th>
      <th id="sessionForm:dataTable:endTime_clone" class="ui-state-default ui-sortable-column" style="width:60px" aria-label="End Time: activate to sort column ascending" role="columnheader" tabindex="0" aria-sort="other">

        <span class="ui-sortable-column-icon ui-icon ui-icon-carat-2-n-s"/>
      </th>
      <th id="sessionForm:dataTable:dynamicColumns:2" class="ui-state-default ui-sortable-column" style="width:80px" aria-label="Session ID: activate to sort column ascending" role="columnheader" aria-sort="other">
        <span class="ui-column-title">Session ID</span>
        <span class="ui-sortable-column-icon ui-icon ui-icon-carat-2-n-s"/>
      </th>
    </tr>
 </thead>
<tbody id="sessionForm:dataTable_data" class="ui-datatable-data ui-widget-content">
<tr class="ui-widget-content ui-datatable-even" role="row" data-ri="0">
<td role="gridcell">

<td role="gridcell">

<td role="gridcell">

<td role="gridcell">
<span title="0.0">0.0</span>

<td role="gridcell">
<span title="41">41</span>

</tr>
<tr class="ui-widget-content ui-datatable-odd" role="row" data-ri="1">
<td role="gridcell">

<td role="gridcell">
<span title="abc_enterprise">abc_enterprise</span>

<td role="gridcell">
<div class="numeric">01/23/2018 14:30:00 </div>
</td>
<td role="gridcell">
<div class="numeric">01/23/2018 15:45:00 </div>
</td>
<td role="gridcell">
<span title="0.0">0.0</span>
</td>
<td role="gridcell">
<span title="40">40</span>
</td>
</tr>

这是部分HTML代码，仅供参考。

我需要根据表标题为表列创建XPath，首先我读取表头并根据标题上的位置获取该列的所有值。

Answer 1

您可以使用以下内容：

.//*[@id='sessionForm:dataTable_data']/tr/td[position()=count(//span[@class='ui-column-title' and text()='Total Revenue']/../preceding-sibling::*)+1]/div

在此xpath中，它将获取Total Revenue的列号，然后使用它来获取该列值。因此，假设一列在它之前消失，那么该值将自动减少1.

希望这有帮助。

Answer 2

Java示例：

// List of title columns
List<WebElement> columns = driver.findElements(By.xpath(".//span[@class='ui-column-title']"));
int i = 1;
boolean stop = False;
WebElement elem = null;
while(i<columns.size() && !stop){
    elem = columns.get(i-1);
    // if the elem has the title stop the loop
    if (elem.getText().equalsIgnoreCase("Total Revenue")){
        stop = True;
    }
}
// The i variable has the right position to take the values for the column
List<WebElement> Revenue_rows = driver.findElements(By.xpath('.//td[(position() > (i-1)) AND (position()<= i)]'))

根据表标题为表数据创建XPATH
