Moana Proxy

In the upper right corner of the browser, click "Settings and Other", and then select the "Options" tab in the window that appears. Once the "General" window opens, locate the "Advanced" tab and click "Open proxy settings" in the menu that appears. Here, in the line "Use a proxy server", select "On". In the "Address" field, you must specify the IP address of the proxy, and in the "Port" field - the port of the proxy. The last thing to do is to click "Save".

Scraping business contacts using regular expressions can be challenging and error-prone, especially considering the variations in contact information formats. Instead of using regular expressions directly, a better approach is to use a dedicated HTML parser like DOMDocument or a library like Simple HTML DOM Parser in PHP. This allows you to navigate the HTML structure and extract relevant information more reliably.

Here's an example using Simple HTML DOM Parser to scrape business contact information

Install Simple HTML DOM Parser:

You can download it from sourceforge and include it in your project, or use Composer:

composer require sunra/php-simple-html-dom-parser

Scraping Script:

find('span.phone-number') as $phoneElement) {
        $contacts[] = $phoneElement->plaintext;
    }

    // Example: Extracting email addresses
    foreach ($html->find('a.email') as $emailElement) {
        $contacts[] = $emailElement->plaintext;
    }

    // Add more logic to extract other types of contact information

    return $contacts;
}

// Example usage
$url = 'https://example.com/business-page';
$businessContacts = scrapeBusinessContacts($url);

// Print the extracted contacts
print_r($businessContacts);

2. Adjust the HTML element selectors (span.phone-number, a.email, etc.) based on the structure of the business contacts on the target website.

Remember:

• Web scraping might violate the terms of service of some websites, so always check and comply with the website's policies.
• The HTML structure of a webpage can change, so your scraping code might need adjustments if the website updates its design.
• Web scraping may be subject to legal and ethical considerations. Ensure you have the right to scrape and use the data.

Working with dynamically loaded buttons and forms on a webpage in Selenium can be challenging, as these elements may not be present when the page initially loads. To interact with these elements, you'll need to wait for them to become available.

You can use the following strategies to work with dynamically loaded elements in Selenium:

Explicit waits:

Explicit waits allow you to wait for a specific element to become available before interacting with it. This can be useful when working with dynamically loaded elements, as you can wait for the element to appear, become clickable, or disappear.

Here's an example using Python:

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('your_url')

# Replace 'dynamic_button_id' with the ID of the dynamic button
dynamic_button = WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.ID, 'dynamic_button_id'))
)
dynamic_button.click()

# Rest of your code

driver.quit()

In this example, we use the WebDriverWait class to wait for the dynamic_button_id element to become clickable. The element_to_be_clickable() method takes a tuple containing the locator strategy and the element's identifier. The 10 parameter specifies the maximum amount of time to wait for the element, in seconds.

1. Implicit waits:

Implicit waits set a global timeout for the WebDriver to wait for elements to become available before throwing a NoSuchElementException. While implicit waits can be useful for some scenarios, they are not recommended for waiting for elements to become clickable, as they can lead to unexpected behavior.

2. Polling:

Polling is a technique where you repeatedly check for the presence of an element at a specific interval. This can be done using a loop and the WebDriverWait class. However, polling can be inefficient and may not be the best solution for waiting for elements to become available.

3. JavaScript execution:

In some cases, you may need to use JavaScript to interact with dynamically loaded elements. You can use the execute_script() method to run JavaScript code that interacts with the webpage.

Here's an example of using JavaScript to click a dynamic button:

from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Chrome()
driver.get('your_url')

# Replace 'dynamic_button_id' with the ID of the dynamic button
dynamic_button = driver.find_element(By.ID, 'dynamic_button_id')
driver.execute_script("arguments[0].click();", dynamic_button)

# Rest of your code

driver.quit()

In this example, we use the execute_script() method to run a JavaScript code that clicks the dynamic_button_id element.

When working with dynamically loaded elements, it's essential to use the appropriate waiting strategy to ensure that your code interacts with the elements only when they are available and in the correct state.

Google Chrome doesn't have a built-in function to work with a proxy server, although there is such an item in the settings. But when you click on it, you are automatically "redirected" to the standard proxy settings in Windows (or any other operating system).

The first thing you need to do to use a proxy in your browser is to make the necessary settings. In Google Chrome browser, go to "Network" and then find and click on "Change proxy settings". In the "Internet properties" window that opens, go to "Connection" and click on the "Network settings" button at the bottom. When a new window opens, check the "Use proxy server for local connections" box and the "Do not use proxy server for local addresses" box. Enter the proxy port and IP address in the corresponding fields, close the window and click "OK".
