c# - 如何使用 Selenium Webdriver 根据目标行获取表格单元格文本

Question

我正在尝试根据单元格索引和行标识符获取表格单元格的文本。在下面的示例表中，我想获取与单元格“text6”位于同一行的单元格的文本。这是我正在处理的表格示例:

<table cellspacing="0" cellpadding="0" class="fixedTable" id="PackageTable_dataTable" style="width: 1262px;">
<tbody class="tableData" id="PackageTable_dataBody">
<tr height="24px" uid="section1" index="0" class="alternateRow">
<td><div style="overflow: hidden; width: 193px;"><span title="text1">text1</span></div></td>
<td><div style="overflow: hidden; width: 57px;"><span title="text2">text2</span></div></td>
<td><div style="overflow: hidden; width: 115px;"><span title="text3">text3</span></div></td>
</tr>
<tr height="24px" uid="section2" index="1" class="alternateRow">
<td><div style="overflow: hidden; width: 193px;"><span title="text4">text4</span></div></td>
<td><div style="overflow: hidden; width: 57px;"><span title="text5">text5</span></div></td>
<td><div style="overflow: hidden; width: 115px;"><span title="text6">text6</span></div></td>
</tr>
<tr height="24px" uid="section3" index="2" class="alternateRow">
<td><div style="overflow: hidden; width: 193px;"><span title="text7">text7</span></div></td>
<td><div style="overflow: hidden; width: 57px;"><span title="text8">text8</span></div></td>
<td><div style="overflow: hidden; width: 115px;"><span title="text9">text9</span></div></td>
</tr>
</tbody>
</table>

这是我的非工作代码:

public static string returnTableCellValue(string TableID, string TableRowIdentifier, int targetCellIndex)
        {
            string cellValue = string.Empty;
            try
            {
                IWebElement baseTable = Global.driver.FindElement(By.Id(TableID));
                // gets all table rows
                ICollection<IWebElement> rows = baseTable.FindElements(By.TagName("tr"));
                // for every row
                foreach (IWebElement row in rows)
                {
                    if (row.FindElement(By.XPath("//span[text()='" + TableRowIdentifier + "']")).Displayed)
                    {
                        Global.log.WriteLine("row identifier found!");
                        IWebElement key = row.FindElement(By.XPath("//td[" + targetCellIndex + "]"));
                        IWebElement keySpan = key.FindElement(By.TagName("span"));
                        cellValue = keySpan.Text;
                    }
                }
                return cellValue;
            }

            catch (Exception ex)
            {
                Global.log.WriteLine("returnTableCellValue exception: " + ex.ToString());
                return string.Empty;
            }
        }

知道怎么做吗？

Answer 1

代码中的以下行将在 FindElement 未找到符合条件的元素的第一行抛出 NoSuchElementException。

if (row.FindElement(By.XPath("//span[text()='" + tableRowIdentifier + "']")).Displayed)

改为使用 FindElements()，如下所示:

IWebElement matchedRow = null;
try
{
    foreach(var row in rows)
    {
        if(row.FindElements(By.XPath("td/span")).FirstOrDefault(cell => cell.Text.Trim().Equals(TableRowIdentifier)) != null)
        {
            matchedRow = row;
            break;
        }
    }
}
catch (NoSuchElementException)
{
    //couldnot find 
    matchedRow = null;
}

if(matchedRow !=null)
{
    cellValue = matchedRow.FindElement(By.XPath(string.Format("td[{0}]/span",targetCellIndex)).Text;
}

return cellValue;
