SQLite is a relational database management system, and XML is a markup language for encoding structured data. SQLite itself doesn't inherently support XML parsing. However, if you have XML data that you want to store in SQLite or retrieve from SQLite, you can follow a process of converting between XML and SQLite data.

Here's a general approach:

Storing XML in SQLite:

1. Convert XML to a Text Representation: Convert your XML data into a text representation, for example, by serializing it as a string. This can be done using XML serialization libraries available in your programming language.

2. Store the Text in a SQLite Table: Create a table in SQLite with a column to store the serialized XML text. Insert the XML data into this table.

CREATE TABLE xml_data (id INTEGER PRIMARY KEY, xml_text TEXT);
INSERT INTO xml_data (xml_text) VALUES ('value');

Retrieving XML from SQLite:

1. Retrieve the Text from the SQLite Table: Query the SQLite table to retrieve the stored XML text.

SELECT xml_text FROM xml_data WHERE id = 1;

Convert Text to XML: Deserialize the retrieved text back into XML using XML parsing libraries.

Example in Python using the xml.etree.ElementTree module:

import xml.etree.ElementTree as ET

# Retrieve XML text from SQLite (replace with actual retrieval logic)
xml_text = "value"

# Parse XML text
root = ET.fromstring(xml_text)

# Access XML elements as needed
element_value = root.find('element').text
print("Element value:", element_value)

This is a basic approach, and the exact steps may depend on the programming language you're using and the tools available in that language for XML serialization and deserialization.

If you're working with XML data frequently, consider exploring databases designed for handling XML, such as XML databases or document-oriented databases, which may offer more native support for XML storage and retrieval. SQLite, being a relational database, is optimized for relational data rather than XML.

In PHP, you can generate JSON data using the json_encode function, and in Swift (iOS/macOS), you can parse it using JSONSerialization or Codable depending on your needs.

Here's an example of generating JSON in PHP and parsing it using NSJSONSerialization in Swift

PHP (Generate JSON):

 'John Doe',
    'age' => 25,
    'city' => 'New York',
    'is_student' => true
);

// Encode data to JSON
$jsonData = json_encode($data);

// Output JSON
echo $jsonData;
?>

In this PHP script, the json_encode function is used to convert the PHP associative array into a JSON string.

Swift (Parse JSON using NSJSONSerialization):

import Foundation

// Sample JSON data as a string
let jsonString = """
{
    "name": "John Doe",
    "age": 25,
    "city": "New York",
    "is_student": true
}
"""

// Convert JSON string to Data
if let jsonData = jsonString.data(using: .utf8) {
    do {
        // Parse JSON data using NSJSONSerialization
        if let jsonObject = try JSONSerialization.jsonObject(with: jsonData, options: []) as? [String: Any] {
            // Access parsed JSON data
            let name = jsonObject["name"] as? String ?? ""
            let age = jsonObject["age"] as? Int ?? 0
            let city = jsonObject["city"] as? String ?? ""
            let isStudent = jsonObject["is_student"] as? Bool ?? false

            // Print parsed data
            print("Name: \(name)")
            print("Age: \(age)")
            print("City: \(city)")
            print("Is Student: \(isStudent)")
        }
    } catch {
        print("Error parsing JSON: \(error.localizedDescription)")
    }
}

In this Swift code, the JSONSerialization class is used to parse the JSON string (converted to Data) into a Swift dictionary ([String: Any]). You can then access individual values from the parsed JSON data.

Note: Ensure that the JSON structure in your PHP script and Swift code aligns, and handle errors appropriately during parsing. Additionally, consider using Codable in Swift for a more convenient way to work with JSON data if your data structure matches your Swift model.

In the browser settings, select "Open Browser Settings" and then, finding the "Advanced" button, go to the "System" section. Click on the button "Open proxy server settings for computer" and in the section "Manual proxy settings" move the slider to the position "On". Now enter in the appropriate fields the IP address, proxy, port and click "Save".

It means that now all the traffic is sent to a VPN server (which can be an ordinary proxy). This is a kind of warning that the remote server can now collect data. Therefore, you should use only well-tested VPN services.

The easiest way to set up a home proxy server is to install a router that supports this function. Then get the proxy data (provided by the service in which it is "rented") and enter it in the router settings. If there is no need for a common proxy (for all devices at once), then it should be configured separately for each device with the help of the utilities integrated in the OS for changing the connection properties.
