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.

To scrape an image using Selenium in C#, you can find the image element on the web page and then retrieve the image source (URL) or download the image file. Here's a simple example:

using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

class Program
{
    static void Main()
    {
        // Set up the Chrome WebDriver
        using (var driver = new ChromeDriver())
        {
            // Navigate to the web page containing the image
            driver.Navigate().GoToUrl("https://example.com");

            // Find the image element (replace with your actual locator)
            IWebElement imageElement = driver.FindElement(By.XPath("//img[@id='your_image_id']"));

            // Get the source URL of the image
            string imageUrl = imageElement.GetAttribute("src");

            Console.WriteLine("Image Source URL: " + imageUrl);

            // Download the image (optional)
            DownloadImage(imageUrl);
        }
    }

    // Function to download the image
    static void DownloadImage(string imageUrl)
    {
        using (var webClient = new System.Net.WebClient())
        {
            // Replace "downloaded_image.jpg" with your desired file name
            webClient.DownloadFile(imageUrl, "downloaded_image.jpg");
            Console.WriteLine("Image Downloaded Successfully.");
        }
    }
}

In this example:

The Chrome WebDriver is set up.

The program navigates to a web page (replace "https://example.com" with the actual URL).

The image element is located using a locator (replace "//img[@id='your_image_id']" with the actual XPath or other locator for your image).

The source URL of the image is retrieved using GetAttribute("src").

Optionally, the DownloadImage function is called to download the image using WebClient. Adjust the file name and path as needed.

Setting up a proxy on your TV depends on the type of TV and the operating system it uses. Some smart TVs run on platforms like Android TV, webOS, or Tizen, which allow you to install apps and configure network settings. Here, I will provide instructions for popular smart TV platforms:

Android TV:
- Press the "Home" button on your remote control.
- Scroll up or down to "Apps" and highlight "Settings."
- Select "Network" or "Network & Internet."
- Choose "Advanced settings" or "More settings."
- Select "Manage proxy settings" or "Proxy settings."
- Choose "Enable proxy" and enter the proxy server address, port, and authentication credentials (if required).
- Save the settings and restart your TV if necessary.

webOS (LG Smart TV):
- Press the "Home" button on your remote control.
- Scroll up or down to "Settings" and select it.
- Choose "All Settings" or "General."
- Select "Network" or "Internet."
- Choose "Wi-Fi Direct" or "Wired" depending on your connection type.
- Select "Advanced settings" or "Internet settings."
- Choose "Manual proxy settings" and enter the proxy server address, port, and authentication credentials (if required).
- Save the settings and restart your TV if necessary.

Tizen (Samsung Smart TV):
- Press the "Menu" button on your remote control.
- Scroll up or down to "Settings" and select it.
- Choose "General" or "Network."
- Select "Network status" or "Internet."
- Choose "Wi-Fi" or "Wired" depending on your connection type.
- Select "Advanced settings" or "Internet settings."
- Choose "Manual proxy settings" and enter the proxy server address, port, and authentication credentials (if required).
- Save the settings and restart your TV if necessary.

It means that the address of such a server changes periodically. This is useful if the user wants to be as anonymous as possible when surfing the web.

All modern Smart TVs allow you to use proxies to connect to the Internet or local network (both on Android and Tizen OS). You have to go to the device settings, open "Network" tab (can be named as "Ethernet"), and then in "Advanced settings" to activate the proxy, if necessary - specify its settings.
