Adb Proxy

You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

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.

It seems there might be a confusion in your request. Polly is a resilience and transient-fault-handling library in C# for dealing with issues like network failures, timeouts, and other transient errors. It is not directly related to parsing courses or web scraping.

If you are looking to parse a course from a website using C#, you might want to use a combination of HTTP requests and HTML parsing libraries. Here's a basic example using the HtmlAgilityPack library for HTML parsing and HttpClient for making HTTP requests

Install HtmlAgilityPack:

You can install the HtmlAgilityPack library using NuGet Package Manager Console:

Install-Package HtmlAgilityPack

Example Code

Here's a simple example of how you might use HttpClient and HtmlAgilityPack to parse course information from a website:

using System;
using System.Net.Http;
using HtmlAgilityPack;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        // URL of the course page
        string courseUrl = "https://example.com/courses";

        // Make an HTTP request to get the HTML content
        using (HttpClient client = new HttpClient())
        {
            string htmlContent = await client.GetStringAsync(courseUrl);

            // Use HtmlAgilityPack to parse the HTML
            HtmlDocument doc = new HtmlDocument();
            doc.LoadHtml(htmlContent);

            // Extract course information (modify as per the HTML structure)
            HtmlNodeCollection courseNodes = doc.DocumentNode.SelectNodes("//div[@class='course']");
            if (courseNodes != null)
            {
                foreach (HtmlNode courseNode in courseNodes)
                {
                    string courseTitle = courseNode.SelectSingleNode(".//h2")?.InnerText.Trim();
                    string courseDescription = courseNode.SelectSingleNode(".//p")?.InnerText.Trim();

                    Console.WriteLine($"Title: {courseTitle}");
                    Console.WriteLine($"Description: {courseDescription}");
                    Console.WriteLine();
                }
            }
            else
            {
                Console.WriteLine("No course information found on the page.");
            }
        }
    }
}

This is a basic example, and you'll need to adapt it based on the actual HTML structure of the course page you are working with.

It is recommended to use private IPv6 proxies with dedicated IP in order to work with Instagram correctly, and most importantly - securely. With such connection interception of traffic is practically impossible, directly Instagram also will not ban the connection.
