In Perl, regular expressions (regex) are a powerful tool for parsing and manipulating text. Below is a basic example of using Perl regex to parse text. Please note that the regex patterns and the parsing logic depend on the specific structure of your text data.

Let's assume you have a simple text string with information about people, and you want to extract names and ages. Here's an example:

use strict;
use warnings;

my $text = "John Doe, age 30; Jane Smith, age 25; Bob Johnson, age 40";

# Define a regex pattern to match names and ages
my $pattern = qr/(\w+\s+\w+),\s+age\s+(\d+)/;

# Use the regex pattern to extract information
while ($text =~ /$pattern/g) {
    my $name = $1;
    my $age = $2;
    print "Name: $name, Age: $age\n";
}

In this example:

• The text contains information about people, where each entry is separated by a semicolon.

• The regex pattern (\w+\s+\w+),\s+age\s+(\d+) is used to match names and ages. Breaking down the pattern:

  • (\w+\s+\w+): Matches names consisting of one or more word characters (letters, digits, underscores) separated by whitespace.
  • ,: Matches the comma separating the name and age.
  • \s+age\s+: Matches the string "age" surrounded by whitespace.
  • (\d+): Matches one or more digits representing the age.

• The while ($text =~ /$pattern/g) loop iterates through matches found in the text.

• Inside the loop, $1 and $2 capture the matched name and age, respectively.

When scraping dates from a website using Java, the SimpleDateFormat class is commonly used for parsing and formatting dates. Below is an example demonstrating how to scrape dates from a webpage and parse them using SimpleDateFormat. Additionally, you can use a library like Jsoup for HTML parsing.

Make sure to replace the URL, HTML parsing logic, and date format patterns with your specific requirements.

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateScrapingExample {

    public static void main(String[] args) {
        String url = "https://example.com"; // Replace with the URL of the webpage containing dates

        try {
            // Fetch HTML content using Jsoup
            Document document = Jsoup.connect(url).get();

            // Replace the following logic with the actual HTML parsing logic for dates
            Element dateElement = document.selectFirst(".date-selector"); // Replace with the appropriate selector
            String dateString = dateElement.text(); // Get the text content of the element

            // Parse the date using SimpleDateFormat
            SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            Date parsedDate = inputFormat.parse(dateString);

            // Format the date for display
            SimpleDateFormat outputFormat = new SimpleDateFormat("EEE, MMM d, yyyy 'at' h:mm a");
            String formattedDate = outputFormat.format(parsedDate);

            // Print the formatted date
            System.out.println("Scraped Date: " + formattedDate);
        } catch (IOException | ParseException e) {
            e.printStackTrace();
        }
    }
}

In this example:

• We use the Jsoup library to fetch the HTML content from the specified URL.
• We assume there is an HTML element with a class name of "date-selector" containing the date text. Adjust the selector based on the structure of the webpage you are scraping.
• The SimpleDateFormat class is used to parse the scraped date string into a Date object using the specified input format.
• Another SimpleDateFormat is used to format the date into a more readable output format.

Note: Make sure to handle exceptions appropriately, and adjust the date format patterns according to the actual format used on the webpage.

If Selenium is returning a blank page when you query it, there could be several reasons for this issue. Here are some common causes and solutions:

1. Timing Issues

Selenium might be trying to interact with the page before it has fully loaded. Ensure that you use explicit waits (WebDriverWait) to wait for the elements to be present, visible, or interactive before interacting with them.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome()
driver.get("https://example.com")

# Wait for the page title to be present
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.TAG_NAME, 'title')))

# Continue with your script...

2. Incorrect Locator or Query

Double-check your locators and queries to ensure that you are selecting the correct elements. Incorrect locators might lead to the selection of non-existent or hidden elements.

3. Browser Window Size

In headless mode or when the browser window is too small, elements might not be visible. Ensure that your script maximizes the browser window or sets an appropriate window size.

driver.maximize_window()

4. JavaScript Errors

Check the browser console for any JavaScript errors that might be affecting the page. Use console.log statements in JavaScript to debug if needed.

console.log("Debug message from JavaScript");

5. Network Issues

Network issues might prevent the page from loading completely. Ensure that your network connection is stable.

6. Browser Extensions

Certain browser extensions might interfere with Selenium. Disable extensions or use a clean browser profile for testing.

7. Headless Mode Issues

If you are running Selenium in headless mode, try running the script in non-headless mode to see if the issue persists. Some websites may behave differently in headless mode.

8. Check for Captchas or Security Measures

Some websites use captchas or additional security measures that could interfere with automated scripts. Ensure that your script is not encountering captchas.

9. Web Page Structure Changes

Web pages are dynamic, and changes in the structure of the page might affect your script. Inspect the HTML source code of the page to ensure that your locators are still valid.

10. Logging

Add logging statements to your script to output information at different stages. This can help in identifying where the issue might be occurring.

11. Browser Version Compatibility

Ensure that your Selenium WebDriver version is compatible with the browser version you are using. Update your WebDriver if necessary.

To connect your router to a proxy server, follow these steps:

1. Access router admin interface (usually 192.168.1.1)
2. Log in with default or custom credentials
3. Navigate to LAN/Network settings
4. Find and open Proxy Server settings
5. Enter proxy server type, IP, port, and authentication if needed
6. Save and apply changes
7. Update device proxy settings to use router's proxy server

To deactivate the proxy server on Windows 10, you need to perform the following steps:
Open the "Windows Settings" menu.
Go to the "Network and Internet" tab.
Open the "Proxy Server" section.
Deactivate the "Use setup script" option.
Deactivate "Use proxy server" option. Reboot your computer. If the proxy server option has not been disabled, deactivate the "Define parameters automatically" option in the "Proxy server" section. After that you have to restart your PC again.
