使用 Apache POI-Selenium Web 驱动程序将动态 Web 元素写入 XLSX

Question

您好，我正在开发 Selenium Webdriver，我有一个带有下拉菜单的网站，必须选择下拉值，然后单击一个按钮来加载整个页面。页面加载后，必须使用 xpath 从网页中查找文本。我想将下拉文本写入 xlx 文件，并且我想将文本（从 xpath 中找到）写入 xlx。这两个值都是动态的。如何开始，任何代码都可以帮助我。 不使用 maven 和 selenium 我想将数据写入 excel 文件 下面是我要写入excel文件的元素的屏幕截图

我已经写了获取下拉值和 xpath 文本- 想将StockScrip和Pattern写入excel文件

很久以前就尝试过类似的东西，使用 Apache POI lib，你也可以使用 JExcel，但据我所知它几乎没有限制。

在我的网站上找到场景：mylearnings.net

为了完整起见，在此处添加相同的内容：

场景：

• 考虑一个 Excel 文件，其中包含一个表格，其中包含脚本名称、CostPrice、Quantity、Price 、Valuation(PriceQuantity)、Profit(Valuation-(CostPriceQuantity)) 等列。
• 需要每天更新不同股票的价格单元，并据此计算估值和利润。

• 以下是此场景的代码。即使您没有得到场景，代码也会使用 cmets 更新，因此您将了解如何使用 HSSF API 的不同功能。

  public static void writeToExcelHSSF(String filename)
  {
  try{
      //Create a workbook, as here we are trying to modify an Existing file need to provide FileInputStream as argument               
      HSSFWorkbook wb = new HSSFWorkbook(new FileInputStream(path + xlsFile));
  
      //FileOutputStream will be needed while writing changes back to a xls file
      FileOutputStream stream = new FileOutputStream(path + "final1.xls");
  
      //Get sheet by providing index of the sheet
      HSSFSheet sheet = wb.getSheetAt(0);
  
      //Creating a evaluator, it will be used to evaluate formula of a cell
      HSSFFormulaEvaluator evaluator = new HSSFFormulaEvaluator(wb); 
  
      //Get numder of rows of a sheet 
      int rows = sheet.getPhysicalNumberOfRows();
      System.out.println("Sheet " + wb.getNumberOfSheets() + " \"" + wb.getSheetName(0) + "\" has " + rows    + " row(s).");
  
      //Create a row object;
      HSSFRow row;
  
      //Different cell objects
      HSSFCell scriptCell;
      HSSFCell priceCell;
      HSSFCell valuationCell;
      HSSFCell profitCell;
      String scriptName;
  
      for(int k=1;k< rows;k++){
  
                  //get row based on index(row number)    
                  row = sheet.getRow(k);
  
                  //get particular cell of a row                  
                  scriptCell = row.getCell(9);
  
                  //get string value from the cell
                  scriptName =scriptCell.getStringCellValue();
  
                  priceCell =row.getCell(5);
                  valuationCell =row.getCell(6);
                  profitCell =row.getCell(7);
  
                  //set value in a cell, (here parseStocks is just a user defined function to fetch value of a stock)
                  priceCell.setCellValue(parseStocks(path + filename,scriptName));
  
                  //Trigger cache clearance, so evaluation of formula on this cell is done with latest value
                  evaluator.notifyUpdateCell(priceCell);
  
                  //Re-evaluate formula of a cell
                  evaluator.evaluateFormulaCell(valuationCell);
                  evaluator.evaluateFormulaCell(profitCell);
      }
  
      //writing back workbook to output stream
      wb.write(stream);
      stream.close();
  }
  catch( IOException e)
  {
  e.printStackTrace();
  }   
  }
