任务-从AMAZON打印所有产品描述和价格我使用列表并使用for循环对其进行迭代

发生-仅打印一种产品信息和价格，并打印直到for循环符合条件

代码：

List<WebElement> products = driver.findElements(By.xpath("//div[@class=\"s-result-list s-search-results sg-row\"]//descendant::span[@class=\"a-size-base-plus a-color-base a-text-normal\"]"));
        int count = products.size();
        System.out.println(count);


    //using XLS reader class to make runtime excel sheet and add column
    Xls_Reader reader = new Xls_Reader(prop.getProperty("Excel"));
    if (!reader.isSheetExist("ProductData")) {
        reader.addSheet("ProductData");
        reader.addColumn("ProductData", "Name of Product");
        reader.addColumn("ProductData", "Price of Product");
    }

    // for loop to set cell data of product description and product price
    for (int i = 0; i <= count; i++) {
        String prod_desc = driver.findElement(By.xpath("//span[@class=\"a-size-base-plus a-color-base a-text-normal\"]")).getText();
        System.out.println("Done111");
        reader.setCellData("ProductData", "Name of Product", i, prod_desc);

        String prod_price= driver.findElement(By.xpath("//div[@class=\"a-section a-spacing-none a-text-center\"]//descendant::span[@class=\"a-price-whole\"]"
        )).getText(); System.out.println(prod_price);
        reader.setCellData("ProductData", "Price of Product", i, prod_price);            
    }
    }
    catch(Exception e) {
        e.printStackTrace();
    }

结果：

您可以添加html吗。这将有助于解决您的问题

与此同时，请尝试以下操作：

library(dplyr)
library(tidyr)
df1 %>%
  pivot_longer(cols  = -X1) %>% 
  separate_rows(value, sep="(?<=\\]),\\s*") %>%
  transmute(Group = LETTERS[row_number()], ID = value) %>%
  mutate(ID = str_extract_all(ID, "\\d+")) %>% 
  unnest(c(ID))
# A tibble: 13 x 2
#   Group ID   
#   <chr> <chr>
# 1 A     1    
# 2 A     2    
# 3 A     3    
# 4 B     4    
# 5 B     6    
# 6 B     5    
# 7 C     7    
# 8 C     8    
# 9 D     9    
#10 D     10   
#11 D     11   
#12 D     12   
#13 D     13

Answer 2

在xpath之后，您将从首页获得所有描述的列表

List<WebElement> descriptions = driver.findElements(By.xpath(".//span[@class='a-size-base-plus a-color-base a-text-normal']"));

使用xpath之后，您将获得所有价格的列表

List<WebElement> prices = driver.findElements(By.xpath(".//span[@class='a-price-whole']"));

由于描述列表和价格列表的计数都将相同，因此，我们将迭代循环并从两个列表的每个元素中获取文本。

for(int i = 0; i < descriptions.size(); i++) {
        String desc = descriptions.get(i).getText();
        String price = prices.get(i).getText();
        System.out.println(desc +":"+ price);
}

无法使用xpath获取产品列表
