java - Selenium 网络驱动程序 : Help getting specific row data from a table

Question

我有一个包含 12 列的表，其中一列名为“数量”，我需要做的是找出哪一列是数量列，然后从表中获取该列的所有数据。

这是我编写的一些粗略代码，但目前它只是为我提供表中的所有数据，而不是我需要的部分。

// Get the table name
WebElement table = driver.findElement(By.className("compact"));

        // Get all the Table headers and look for one the element called quantity.
        List<WebElement> allHeaders = table.findElements(By.tagName("th"));
        System.out.println("This is the total numbers of headers" + allHeaders.size());
        int quantityHead = 0;

        // Get the column where the quantity is listed
        for(WebElement header : allHeaders)
        {
            quantityHead++;
            if(header.getText().equalsIgnoreCase("Quantity"))
            {
                System.out.println(header.getText());
                System.out.println(quantityHead + " is the column number for the quantity");
            }
        }

        // Now get all the TR elements from the table
        List<WebElement> allRows = table.findElements(By.tagName("tr"));
        System.out.println("This is how many allRows: " + allRows.size());

        // This is how many items are in the order item table. number of rows - 1 coz top row is the headings
        int z = allRows.size() - 1;
        System.out.println("This is how many items are in the table : " + z );

        // Work out the cells we need to get by
        //  iterate over all the td
        for (WebElement row : allRows) {

            // now we have all the td
            List<WebElement> cells = row.findElements(By.tagName("td"));

            for (WebElement cell : cells) {

             for(int x=0; x <= allHeaders.size(); x++)
             {
                 int y = x;

                 // if y = the value where the qty header is then output the text of that cell
                 if(y == quantityHead )
                 {
                     System.out.println();
                     System.out.println("The quanity is: " + cell.getText());
                 }
             }
         }
        }

首先确定数量在表中的列位置。然后通过xpath找到元素

WebElement table = driver.findElement(By.className("compact"));

List<WebElement> th=table.findElements(By.tagName("th"));
    int col_position=0;
    for(int i=0;i<th.size();i++){
        if("quantity".equalsIgnoreCase(th.get(i).getText())){
            col_position=i+1;
            break;
        }
    } 
List<WebElement> FirstColumns = table.findElements(By.xpath("//tr/td["+col_position+"]"));
    for(WebElement e: FirstColumns){
        System.out.println(e.getText());
    }    

希望这有帮助
