java - How make System.out.println collect links only with child p tags?

Question

How make System.out.println show only links with /p/ ? I'm trying to write a program that would display all links by hashtag on Instagram. I was able to parse all links with the "a" tag. How can I now select links to a photo where /P/ is available?

        String hashtag = null;

        driver.get("https://www.instagram.com/explore/tags/"+hashtag);


        String link_include= "/p/";
       List<WebElement> all_links = driver.findElements(By.tagName("a"));

             if (all_links.contains(link_include)){
                    //What do I need to write here for the variable to show links only with the /p/ ?can I use the append method? And How ?
                }
            }

    }

To create a list of the <a> tags having a clild <p> tag you can use either of the following Locator Strategies:

• xpath:

  List<WebElement> all_links = driver.findElements(By.xpath("//a[.//p]"));
  

• To print the link texts using Java8's stream() and getText():

  System.out.println(driver.findElements(By.xpath("//a[.//p]")).stream().map(element->element.getText()).collect(Collectors.toList()));

Ideally you need to induce WebDriverWait for the visibilityOfAllElementsLocatedBy() and you can use either of the following Locator Strategies:

• xpath:

  List<WebElement> all_links = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.xpath("//a[.//p]")));
  

• To print the link texts using Java8's stream() and getAttribute("innerHTML"):

  System.out.println(new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.xpath("//a[.//p]"))).stream().map(element->element.getAttribute("innerHTML")).collect(Collectors.toList()));
