Answer 1

试试这个：

public class TestWebtable {

    public static void main(String[] args) {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.espncricinfo.com/indian-premier-league-2016/engine/match/981019.html");

    int rowNum = 0;

    List<WebElement> lstElements = driver.findElements(By.XPath(".//*[@id='full-scorecard']/div[2]/div/table[1]/tbody/tr/td[contains(@class,'batsman-name')]/a"));
        rowNum = lstElements.Count;

    System.out.println("Total rows are : " + rowNum);
   }
}

Answer 2

我试过了，但你的代码没有用，但无论如何我用谷歌搜索，我发现这个答案满足了我的需求：

WebDriver 驱动 = new FirefoxDriver();

 @BeforeTest
 public void setup() throws Exception {
  driver.manage().window().maximize();
  driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
  driver.get("http://www.espncricinfo.com/indian-premier-league-2016/engine/match/981019.html");
 }

 @AfterTest
 public void tearDown() throws Exception {
  driver.quit();
 }

 @Test
 public void Handle_Dynamic_Webtable() {

  //To locate table.
  WebElement mytable = driver.findElement(By.xpath(".//*[@id='full-scorecard']/div[2]/div/table[1][@class='batting-table innings']"));
  //To locate rows of table.
  List<WebElement> rows_table = mytable.findElements(By.tagName("tr"));
  //To calculate no of rows In table.
  int rows_count = rows_table.size();

  //Loop will execute till the last row of table.
  for (int row=0; row<rows_count; row++){
   //To locate columns(cells) of that specific row.
   List<WebElement> Columns_row = rows_table.get(row).findElements(By.tagName("td"));
   //To calculate no of columns(cells) In that specific row.
   int columns_count = Columns_row.size();
   System.out.println("Number of cells In Row "+row+" are "+columns_count);

   //Loop will execute till the last cell of that specific row.
   for (int column=0; column<columns_count; column++){
    //To retrieve text from that specific cell.
    String celtext = Columns_row.get(column).getText();
    System.out.println("Cell Value Of row number "+row+" and column number "+column+" Is "+celtext);
   }
   System.out.println("--------------------------------------------------");

试试这个

driver.get("http://www.espncricinfo.com/indian-premier-league-2016/engine/match/981019.html");

    int i = 2;
    int rowNum = 0;
    while (true) {

        try {
            driver.findElement(
                    By.xpath(".//*[@id='full-scorecard']/div[2]/div/table[1]/tbody/tr[" + i + "]/td[2]/a"));

            i = i + 2;
            rowNum++;
        } catch (Exception e) {
            break;
        }

    }
    System.out.println("Total rows are : " + rowNum);
