Alibaba Proxy

On the PC you can use SOCKS5 proxies, for example, through the browser Firefox. There are such a function in the settings, you just need to activate it. The only nuance: the connection speed or ping indicators in this case may be slowed down.

Parsing HTML in C++ can be achieved using libraries that provide HTML parsing capabilities. One such popular library is Gumbo, developed by Google. Gumbo is an HTML5 parsing library that provides an easy-to-use API for extracting information from HTML documents.

Here's a basic example of parsing HTML using Gumbo in C++

Install Gumbo Library

Follow the installation instructions on the Gumbo GitHub repository to build and install the library.

Include Gumbo Headers in Your C++ Code:

#include 

Write HTML Parsing Code:

#include 
#include 

void parseHtml(const char* html) {
    GumboOutput* output = gumbo_parse(html);
    // Process the parsed HTML tree
    // ...

    // Clean up
    gumbo_destroy_output(&kGumboDefaultOptions, output);
}

int main() {
    const char* html = "
	
	
	
	
	
	
Hello, World!
";
    parseHtml(html);

    return 0;
}

The parseHtml function takes an HTML string as input, uses Gumbo to parse it, and then you can traverse the resulting parse tree to extract information.

Traverse the Parse Tree:

void traverseNode(GumboNode* node) {
    if (node->type == GUMBO_NODE_ELEMENT) {
        // Handle element node
        GumboElement* element = &node->v.element;
        // Extract tag name: element->tag
        // Process attributes: element->attributes
    } else if (node->type == GUMBO_NODE_TEXT) {
        // Handle text node
        GumboText* text = &node->v.text;
        // Extract text content: text->text
    }

    // Recursively traverse child nodes
    if (node->type != GUMBO_NODE_TEXT && node->v.element.children.length > 0) {
        for (unsigned int i = 0; i < node->v.element.children.length; ++i) {
            traverseNode(static_cast(node->v.element.children.data[i]));
        }
    }
}

void processParsedHtml(GumboNode* root) {
    // Traverse the parsed HTML tree
    traverseNode(root);
}

Modify the traverseNode function according to your needs to extract information from HTML elements and text nodes.

Compile and Run:

Compile your C++ code with the Gumbo library linked.

Run the executable.

Remember to handle memory management properly and check for errors when using Gumbo. The example above provides a basic framework, and you may need to adapt it based on the specific HTML structure you are dealing with.

In Selenium Python, you can use the send_keys method to simulate typing keys into an input field. To press keys correctly, you can use the Keys enumeration provided by the selenium.webdriver.common.keys module. Here's an example of how to use the send_keys method to press keys in Selenium Python:

Install the required package:

pip install selenium

Create a method to press keys in an input field:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

def press_keys(driver, locator, keys_to_press):
    element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(locator))
    element.clear()
    element.send_keys(keys_to_press)
    element.send_keys(Keys.RETURN)

Use the press_keys method in your test code:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Set up the WebDriver
driver = webdriver.Chrome()
driver.maximize_window()

# Navigate to the target web page
driver.get("https://www.example.com")

# Locate the input field
locator = (By.ID, "username")

# Press keys in the input field
press_keys(driver, locator, "your_username")

# Perform any additional actions as needed

# Close the browser
driver.quit()

In this example, we first create a method called press_keys that takes a driver instance, a locator tuple containing the locator strategy and locator value, and a keys_to_press string containing the keys to press. Inside the method, we use the WebDriverWait class to wait for the element to become visible and then clear the input field, send the keys to press, and simulate pressing the Enter key using the Keys.RETURN enumeration value.

In the test code, we set up the WebDriver, navigate to the target web page, and locate the input field using the locator variable. We then call the press_keys method with the driver, locator, and "your_username" as input. After pressing the keys, you can perform any additional actions as needed.

Remember to replace "https://www.example.com", "username", and "your_username" with the actual URL, input field ID or name, and the text you want to type into the input field.

In Selenium, you can check if the DOM of a page is loaded by using JavaScriptExecutor. Here's how you can check:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://www.example.com")

while True:
    try:
        driver.execute_script("return document.readyState")
        if driver.execute_script("return document.readyState") == "complete":
            print("Page is loaded")
            break
    except Exception as e:
        print("Exception occurred")

In this script, the document.readyState property is used to check if the page is loaded or not. In JavaScript, the "complete" value of document.readyState indicates that the page is loaded.

This script will keep running until the page is loaded. Once the page is loaded, it will print "Page is loaded" and break the loop.

Please note that this script assumes that the page is completely loaded when document.readyState is "complete". However, this is not always the case. Sometimes, some elements may still be loading even when document.readyState is "complete". So, it's better to use explicit or implicit waits to wait for specific elements to be present or visible.

It refers to a proxy that changes its IP address according to a set algorithm. This is done to minimize the risk of the proxy being recognized by web applications and to better ensure privacy.
