200 Proxy

To connect a proxy for Instagram, you need to use third-party services. With their help, you can assign a separate proxy for each account, through which the profile will work. An example of a service is Instaplus. You can also use built-in proxies on the site.

You need to go to "Settings", under "Sharing" select "VPN". And there you can either enter the connection parameters manually (address, port number, username and password), or choose a program that automatically connects the user to the proxy (free applications of this type can be found in Google Play).

In Android, you can load and parse XML using the XmlPullParser class provided by Android's org.xmlpull.v1 package. The following example demonstrates how to load and parse XML from a string resource in Android

Assuming you have an XML file (example.xml) in the res/xml directory with the following content:

    Item 1
    Item 2
    Item 3

Now, you can load and parse this XML file in an Android activity:

import android.app.Activity;
import android.content.res.XmlResourceParser;
import android.os.Bundle;
import android.util.Log;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;

import java.io.IOException;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Load and parse XML
        parseXml();
    }

    private void parseXml() {
        try {
            // Get the XML resource parser
            XmlResourceParser parser = getResources().getXml(R.xml.example);

            int eventType = parser.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                if (eventType == XmlPullParser.START_TAG) {
                    // Check the name of the start tag
                    if ("item".equals(parser.getName())) {
                        // Get attributes
                        String id = parser.getAttributeValue(null, "id");
                        String text = parser.nextText();

                        // Process the data (in this example, print it)
                        Log.d("XML Parsing", "ID: " + id + ", Text: " + text);
                    }
                }

                eventType = parser.next();
            }
        } catch (XmlPullParserException | IOException e) {
            e.printStackTrace();
        }
    }
}

In this example:

• getResources().getXml(R.xml.example) is used to obtain an XmlResourceParser for the XML file (example.xml).
• The XmlPullParser is used to iterate through the XML content, and when a start tag is encountered (XmlPullParser.START_TAG), it checks for the tag name ("item" in this case) and retrieves attributes and text content accordingly.

Remember to replace R.xml.example with the actual resource ID for your XML file. This example assumes that the XML file is located in the res/xml directory.

Also, ensure that the XML file is well-formed and follows the XML structure.

To optimize the performance of Selenium with Chrome and Chromedriver, you can consider several strategies:

Latest Versions:
Ensure that you are using the latest version of Chrome and Chromedriver. They are frequently updated to include performance improvements and bug fixes.

Chromedriver Version Compatibility:
Make sure that the version of Chromedriver you are using is compatible with the version of Chrome installed on your machine. Mismatched versions may lead to unexpected behavior.

Headless Mode:
If you don't need to see the browser window during automation, consider running Chrome in headless mode. Headless mode can significantly improve the speed of browser automation.

chrome_options.add_argument('--headless')

Chrome Options:
Experiment with different Chrome options to see how they affect performance. For example, you can set options related to GPU usage, image loading, and more.

chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--blink-settings=imagesEnabled=false')

Page Loading Strategy:
Adjust the page loading strategy. For example, you can set pageLoadStrategy to 'eager' or 'none' if it fits your use case.

chrome_options.add_argument('--pageLoadStrategy=eager')

Timeouts:
Adjust timeouts appropriately. For example, setting script timeouts or implicit waits can help to avoid unnecessary waiting times.

driver.set_script_timeout(10)
driver.implicitly_wait(5)

Parallel Execution:
Consider parallel execution of tests. Running tests in parallel can significantly reduce overall execution time.

Browser Window Size:
Set a specific window size to avoid unnecessary rendering.

chrome_options.add_argument('window-size=1920x1080')

Disable Extensions:
Disable unnecessary Chrome extensions during testing.

chrome_options.add_argument('--disable-extensions')

Logging:
Enable logging to identify any issues or bottlenecks.

service_args = ['--verbose', '--log-path=/path/to/chromedriver.log']
service = ChromeService(executable_path='/path/to/chromedriver', service_args=service_args)

To enable proxies in your MacBook, you need to go to "System Preferences" (from the "Apple" menu), then open "Network", then - specify the type of connection you are using. Then select "Advanced Settings" (can be named as "Advanced"), then click on "Proxy". And then - either set the parameters manually, or specify a configuration file.
