import java.util.*;
    import java.util.concurrent.TimeUnit;    
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.firefox.FirefoxDriver;
    public class downloaddemo {
        String text ;
        String text1 ;
        WebDriver driver;
        void getTextU()
        {
            Scanner s = new Scanner(System.in);
            System.out.println("Enter Text");
            text = s.nextLine();
            text1 = text + " pdf " ; 
            System.out.println(" Searching for " + text1  +  " .......... ");
        }

        public void invokeBrowser()
        {
            System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.19.0-win64\\geckodriver.exe");
            driver = new FirefoxDriver();
            driver.manage().deleteAllCookies();
            driver.manage().window().maximize();
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
            driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS );
            driver.get("https://www.google.com");
            search();

        }
        public void search()
        {
            driver.findElement(By.xpath("//input[@id='lst-ib' and @class='gsfi']")).click(); 

            System.out.println(text1);
            driver.findElement(By.id("lst-ib")).sendKeys(text1);

            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            driver.findElement(By.xpath("//input[@value='Google Search' or  @aria-label='Google Search']")).click();
            //driver.findElement(By.xpath("//span[@class='_ogd b w xsm'] and //a[@href='']")).click();
            /*List<WebElement> list = driver.findElements(By.xpath("//span[@class='_ogd b w xsm']//a[@href]"));
            for (WebElement e : list) {
                String link = e.getAttribute("href");
                System.out.println(e.getTagName() + "=" + link + " , " + e.getText());
            }*/

        }

        public static void main(String[] args) {
            // TODO Auto-generated method stub
            downloaddemo d  = new downloaddemo();
            d.getTextU();
            d.invokeBrowser();
        }

    }

it shows output as follows:

• [pdf] Java The Complete Reference, Seventh Edition.
• [pdf] Java - Oracle.
• [pdf] java - Dr. Ramesh R. Manza.

The problem is how can I load any one of the link which is pdf, the problem is that each anchor tag has different href value .
or
how can I download all pdf .

Answer 1

Using this code I take all the pdf link

    public class testing_solution
    {
           public static WebDriver driver;

            public static void main(String[] args) throws InterruptedException {
                    driver =new ChromeDriver();
                    driver.get("https://www.google.com/search?q=selenium+pdf&rlz=1C1CHZL_enBD739BD739&oq=selenium+pdf&aqs=chrome..69i57j69i60l2j0l3.3815j0j7&sourceid=chrome&ie=UTF-8");
                    List<WebElement> list = driver.findElements(By.xpath(".//*[@class='f kv _SWb']/cite"));

             for (WebElement e : list) {
                 if(e.getText().endsWith(".pdf")){

                     System.out.println(e.getText());
                 }

        }}

First I take the link of the link then check if the link is pdf then I print all the link.

And I get Following Output

Hope it will help you....
