Apt HTTP Proxy

To find out the port of the proxy server, you just need to use any browser (Yandex Browser, Opera, Google Chrome). Then you need to follow the algorithm:

Start the browser. Go to "Settings". In the search box enter the query "proxy". Click on "Proxy settings". In the window that opens, select "Network settings". This will open a tab with the IP address and port of the proxy server.

Automapper is a library primarily used for mapping data between objects in C# applications. It is not specifically designed for parsing XML, but you can use it in conjunction with other libraries, such as XmlDocument or XDocument, to map XML data to C# objects.

Here's a simple example of parsing XML using XDocument and Automapper:

Assuming you have the following XML structure:

  John
  Doe

And a corresponding C# class:

public class PersonDto
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

You can use Automapper to map the XML data to your C# object:

using AutoMapper;
using System;
using System.Xml.Linq;

class Program
{
    static void Main()
    {
        // XML data
        string xmlData = "JohnDoe";

        // Parse XML using XDocument
        XDocument xmlDoc = XDocument.Parse(xmlData);

        // Configure Automapper
        MapperConfiguration config = new MapperConfiguration(cfg =>
        {
            cfg.CreateMap()
                .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.Element("FirstName").Value))
                .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.Element("LastName").Value));
        });

        IMapper mapper = config.CreateMapper();

        // Map XML to C# object
        PersonDto personDto = mapper.Map(xmlDoc.Root);

        // Print the result
        Console.WriteLine($"FirstName: {personDto.FirstName}");
        Console.WriteLine($"LastName: {personDto.LastName}");
    }
}

In this example, we use Automapper's CreateMap method to define a mapping between XElement and PersonDto. The ForMember method is used to specify how each property of PersonDto should be mapped from the corresponding XML element.

Keep in mind that Automapper may be more beneficial when dealing with complex object mappings rather than simple XML parsing scenarios. For straightforward XML parsing tasks, using XDocument or XmlDocument directly might be sufficient.

When using JAXP SAX for parsing XML in Java, you can stop the parsing process after finding a certain field by throwing a SAXException when the desired condition is met. The SAX parser will catch the exception and stop the parsing operation.

Here's a basic example to illustrate how you can achieve this:

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import java.io.IOException;
import java.io.StringReader;

public class StopParsingExample {

    public static void main(String[] args) {
        String xmlData = "Value1Value2Value3";

        try {
            SAXParserFactory factory = SAXParserFactory.newInstance();
            SAXParser saxParser = factory.newSAXParser();

            MyHandler handler = new MyHandler();
            saxParser.parse(new InputSource(new StringReader(xmlData)), handler);

        } catch (ParserConfigurationException | SAXException | IOException e) {
            e.printStackTrace();
        }
    }

    private static class MyHandler extends DefaultHandler {
        private boolean stopParsing = false;

        @Override
        public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
            // Check if the desired field is found
            if ("field".equals(qName)) {
                String fieldValue = attributes.getValue("attr"); // Change "attr" to the actual attribute name
                if ("Value2".equals(fieldValue)) { // Change "Value2" to the desired value
                    stopParsing = true;
                    throw new SAXException("Stop parsing"); // Throw SAXException to stop parsing
                }
            }
        }

        @Override
        public void characters(char[] ch, int start, int length) throws SAXException {
            // Process character data if needed
        }

        @Override
        public void endElement(String uri, String localName, String qName) throws SAXException {
            // Perform actions when an element ends
        }

        @Override
        public void endDocument() throws SAXException {
            System.out.println("Parsing completed.");
        }
    }
}

In this example, the MyHandler class extends DefaultHandler, and the startElement method is overridden to check for the desired field. If the condition is met, it sets stopParsing to true and throws a SAXException. The parsing process will stop, and the endDocument method will be called.

Adjust the conditions and values according to your specific use case. Keep in mind that stopping parsing abruptly may not be a standard practice, and you should carefully consider the impact on your application's behavior.

To connect to the Internet via a proxy server, you need to configure your browser or operating system to use the proxy server. Here's a general guide for setting up a proxy server using a web browser:

1. Open your web browser.

2. Access the browser settings or preferences:
- On Windows: Click the three-dot menu in the top-right corner and select "Settings."
- On macOS: Click the Apple menu in the top-left corner, select "System Preferences," and click "Network."
- On Linux: Click the menu button in the top-right corner, select "Settings," and click "Network."
- On Android: Open the "Settings" app and tap "Network & internet."
- On iOS: Open the "Settings" app and tap "Wi-Fi."

3. Locate the proxy settings:
- On Windows: Under "Network," click "Proxy settings."
- On macOS: Click the "Advanced" button and go to the "Proxies" tab.
- On Linux: Click the "+" button to add a new proxy.
- On Android: Tap "Private DNS" and "Static IP address" under "Advanced options."
- On iOS: Tap "Configure Proxy" under the active Wi-Fi network.

4. Enter the proxy server address, port, and authentication details (if required):
- Proxy server address: Enter the domain name or IP address of the proxy server (e.g., http://proxy-server).
- Port: Enter the port number used by the proxy server (e.g., 8080).
- Username and Password (optional): If the proxy server requires authentication, enter the username and password provided by the proxy server provider.

5. Save the proxy settings and restart the browser.

To disable a proxy-server in Yandex browser, you need to do the following steps:

Open the browser. Click on the icon "?" in the upper right corner. Go to "Settings". Type "proxy" in the search box. Click on "Proxy settings". In the tab that opens, select "Network settings". Disable the "Use proxy server" option.
