Dontfilter Proxy

To install a proxy server in Google Chrome, you must do the following steps:

Open the browser.
Click the "?" icon in the upper right corner.
Go to "Settings".
Select the "Advanced" option.
Click the "System" tab.
Click on "Open proxy settings for your computer".
Click on "Network settings".
Activate the "Use proxy server" option.
In the tab that opens, specify the IP address of the proxy server. You must enter the address in the field of the protocol to which the proxy server belongs. You can get this information from the provider. Click the "OK" button to save your settings.

In the browser menu (top right corner), find "Settings", and then, under "Network settings", go to "Settings" to select "Manual network configuration". Enter, depending on your network protocol, the IP address, the port and click on "OK". Open any website and in the window that appears, enter the proxy password and login, then click "Ok" again. A successful connection to the site means that the setup is successfully completed.

To scrape tags from XML with Python, you can use the xml.etree.ElementTree module, which is part of the Python standard library. Here's an example of how to extract tags from an XML document

Assuming you have an XML file named example.xml like this:

    
        Item 1
        10.99
    
    
        Item 2
        19.99
    

You can use the following Python code to extract tags:

import xml.etree.ElementTree as ET

# Load the XML file
xml_file_path = 'path/to/example.xml'
tree = ET.parse(xml_file_path)
root = tree.getroot()

# Extract tags
tags = set()
for element in root.iter():
    tags.add(element.tag)

# Print the extracted tags
print("Extracted Tags:")
for tag in tags:
    print(tag)

This example uses xml.etree.ElementTree to parse the XML file, iterates over the elements, and adds each tag to a set to ensure uniqueness. You can modify this example based on your specific needs.

If you want to extract tags with attributes, you can modify the code accordingly. For example:

import xml.etree.ElementTree as ET

# Load the XML file
xml_file_path = 'path/to/example.xml'
tree = ET.parse(xml_file_path)
root = tree.getroot()

# Extract tags with attributes
tags_with_attributes = set()
for element in root.iter():
    tag_with_attributes = element.tag
    if element.attrib:
        attributes = ', '.join([f"{key}={value}" for key, value in element.attrib.items()])
        tag_with_attributes += f" ({attributes})"
    tags_with_attributes.add(tag_with_attributes)

# Print the extracted tags with attributes
print("Extracted Tags with Attributes:")
for tag in tags_with_attributes:
    print(tag)

This example includes attributes in the extracted tags, displaying them in a format like tag_name (attribute1=value1, attribute2=value2). Adjust the code based on your XML structure and specific requirements.

A proxy server is responsible for acting as an intermediary between a client and a destination server, handling requests and responses on behalf of the client. Its primary functions include:

1. Access control: A proxy server can be configured to control access to certain resources or websites based on user authentication, IP address, or other criteria. This can help organizations enforce access policies and restrict access to inappropriate or unauthorized content.

2. Caching: Proxy servers can cache frequently accessed content, such as web pages, images, and other files, to improve performance and reduce the load on the destination server. This can result in faster response times for clients accessing previously cached content.

3. Anonymity and privacy: By routing requests through a proxy server, a client can maintain anonymity and privacy. The proxy server's IP address appears as the source of the request, rather than the client's IP address, which can help protect the client's identity and location.

4. Content filtering: Proxy servers can be configured to filter and block certain types of content, such as malicious websites, adult content, or specific keywords. This can help organizations maintain a safe and secure browsing environment for their users.

5. Performance optimization: Proxy servers can optimize performance by compressing data, using content delivery networks (CDNs), or implementing load balancing techniques. This can result in faster load times and improved user experience.

6. Protocol translation: In some cases, proxy servers can translate between different communication protocols, allowing clients to access resources using a different protocol than the destination server supports.

7. Security: Proxy servers can provide additional security by encrypting data transmitted between the client and the destination server, protecting sensitive information from being intercepted or tampered with during transmission.

In the main window of the program, select "Advanced", then "Options". In the "Basic" section, there is the "Proxy settings" item. Click on "Configuration" and enter the server address, port number, protocol type used and so on.
