如何使用网络驱动程序将边表数据从网络打印到excel的列标题

Question

Issue下面的代码允许我打印列标题或将 Web 表数据打印到 csv 文件中，具体取决于我是否选择了"th"或"td"标签，但不能同时选择两者。

我的问题 如何让它在我的 CSV 输出中同时将"th"和"td"文本打印为 csv？

法典我已经尝试了 2 个版本的代码，但结果是相同的。两个版本都附上了。

代码版本 1

public class WebToCSV {
static WebDriver driver = new FirefoxDriver();
    public static void main(String[] args) throws Throwable   {
        //driver.navigate().to("http://goo.gl/El1PIV");
        driver.navigate().to("http://www.bloomberg.com/markets/stocks/futures");
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        WebElement table = driver.findElement(By.cssSelector
                ("div[class='data-tables first']"));
        List<WebElement> irow = table.findElements
                (By.cssSelector("div[class='data-tables first']  tr"));
        System.out.println("No. of rows in the table are: " + irow.size());
        // Create excel workbook and sheet.
        FileOutputStream fos = new FileOutputStream
                ("/Users/HARSHENDU/Desktop/Selenium_Practice/Stats.csv");
        XSSFWorkbook wb = new XSSFWorkbook();
        XSSFSheet ws = wb.createSheet("WriteToXL");
        for(int r=0; r<irow.size(); r++) {
            WebElement webRow = irow.get(r);
            System.out.println(webRow.getText());
            XSSFRow row = ws.createRow(r);
            List<WebElement> allCells = webRow.findElements(By.tagName("td"));
            for(int c=0; c<allCells.size(); c++) {
                WebElement webCell = allCells.get(c);
                String text = webCell.getText();
                XSSFCell excelCell = row.createCell(c);
                excelCell.setCellValue(text);
            }
            System.out.println("");
        }
        fos.flush();
        wb.write(fos);
        fos.close();
        end();
}
    public static void end() {
        driver.close();
        driver.quit();
    }

}

代码版本 2此版本有 2 组 for 循环，第一组用于以 csv 格式打印列标题，第二组用于打印 webtable 中的所有数据。

public class StatsToxL {
static WebDriver driver = new FirefoxDriver();
public static void main(String[] args) throws Throwable   {
    //driver.navigate().to("http://goo.gl/El1PIV");
    driver.navigate().to("http://www.bloomberg.com/markets/stocks/futures");
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    WebElement table = driver.findElement(By.cssSelector
            ("div[class='data-tables first']"));
    // Get webtable header column row.
    List<WebElement> irow2 = table.findElements
            (By.cssSelector("div[class='data-tables first'] thead tr "));
    System.out.println("No. of rows in the header are: " + irow2.size());
    // Get all webtable rows
    List<WebElement> irow = table.findElements
            (By.cssSelector("div[class='data-tables first'] tbody tr"));
    int iRowCount = irow.size();
    System.out.println("No. of rows in the table are: " + iRowCount);
    // Create excel workbook and sheet.
    FileOutputStream fos = new FileOutputStream
            ("/Users/HARSHENDU/Desktop/Selenium_Practice/Stats.csv");
    XSSFWorkbook wb = new XSSFWorkbook();
    XSSFSheet ws = wb.createSheet("WriteToXL");
    // Iterate over webtable header row and header cells.
    for(int r2=0; r2<irow2.size(); r2++) {
    WebElement webRow2 = irow2.get(r2);
        System.out.println(webRow2.getText());
        XSSFRow row2 = ws.createRow(r2);
        List<WebElement> allCells2 = webRow2.findElements(By.tagName("th"));
        for(int c2=0; c2<allCells2.size(); c2++) {
            WebElement webCell = allCells2.get(c2);
            String text2 = webCell.getText();
            XSSFCell excelCell2 = row2.createCell(c2);
            excelCell2.setCellValue(text2);
        }
        System.out.println("");
        fos.flush();
        wb.write(fos);
    }
    // Iterate over webtable rows and cells.
    for(int r=0; r<iRowCount; r++) {
        WebElement webRow = irow.get(r);
        System.out.println(webRow.getText());
        XSSFRow row = ws.createRow(r);
        List<WebElement> allCells = webRow.findElements(By.tagName("td"));
        for(int c=0; c<allCells.size(); c++) {
            WebElement webCell = allCells.get(c);
            String text = webCell.getText();
            XSSFCell excelCell = row.createCell(c);
            excelCell.setCellValue(text);
        }
        System.out.println("");
    }
    fos.flush();
    wb.write(fos);
    fos.close();
    end();
}
public static void end() {
    driver.close();
    driver.quit();
}
}

Answer 1

更改

webRow.findElements(By.tagName("td"))

自

webRow.findElements(By.xpath("//td | //th"))
