10 月，3 周 Questions & Answers 
List <WebElement> rnum = dr.findElements(By.xpath("//*[@id='leftcontainer']/table/tbody/tr"));
        for(int i=1;i<rnum.size();i++){

            List <WebElement> rowcells = dr.findElements(By.xpath("//*[@id='leftcontainer']/table/tbody/tr[rnum]/td"));

            for(int cnum=0;cnum<rowcells.size();cnum++){
                System.out.println(rowcells.get(cnum).getText());

            }

        }

当我运行这个脚本时，它抛出了一个错误

我试了两次，但都没用

    以下是您的webtable的答案

    List <WebElement> rnum = 
    dr.findElements(By.xpath("//*[@id='leftcontainer']/table/tbody/tr"));

for(int i=0; i<rnum.size(); i++){

    List <WebElement> rowcells = dr.findElements(By.xpath("//*[@id='leftcontainer']/table/tbody/tr[i]/td"));

    for(int cnum=0;cnum<rowcells.size();cnum++){
            System.out.println(rowcells.get(cnum).getText());
    }
}
