SAAQ Proxy

When parsing RSS feeds and avoiding duplicates, you typically need to maintain a record of previously parsed items and compare new items to this record to ensure that you don't process the same item multiple times. Below is an example using Node.js and the rss-parser library, which simplifies working with RSS feeds.

Install Dependencies

Install the required npm package:

npm install rss-parser

Write the Parsing Script

Create a Node.js script (e.g., parse_rss.js) with the following code:

const Parser = require('rss-parser');
const fs = require('fs');

const parser = new Parser();
const rssFeedUrl = 'https://example.com/rss-feed'; // Replace with the URL of the RSS feed

// Function to load and parse the previously processed items
function loadProcessedItems() {
    try {
        const data = fs.readFileSync('processedItems.json');
        return JSON.parse(data);
    } catch (error) {
        return [];
    }
}

// Function to save the processed items to a file
function saveProcessedItems(processedItems) {
    fs.writeFileSync('processedItems.json', JSON.stringify(processedItems, null, 2));
}

async function parseRSS() {
    const processedItems = loadProcessedItems();
    const feed = await parser.parseURL(rssFeedUrl);

    for (const item of feed.items) {
        // Check if the item has been processed before
        if (!processedItems.includes(item.link)) {
            // Process the new item (replace with your processing logic)
            console.log('New item found:', item.title);

            // Add the item link to the list of processed items
            processedItems.push(item.link);
        }
    }

    // Save the updated list of processed items
    saveProcessedItems(processedItems);
}

// Run the RSS parsing process
parseRSS();

Replace 'https://example.com/rss-feed' with the URL of the RSS feed you want to parse.

Run the Script

Run the script using Node.js:

node parse_rss.js

This script uses the rss-parser library to fetch and parse an RSS feed. It maintains a list of processed item links in a JSON file (processedItems.json). Each time the script runs, it loads the processed items, compares them to the new items in the feed, processes only the new items, and then updates the list of processed items.

Clicking an AJAX button in Selenium can be a bit tricky, as AJAX buttons often rely on JavaScript to perform the click action instead of using the traditional HTML click event. To click an AJAX button in Selenium, you can follow these steps:

1. Locate the AJAX button element using its unique identifier (e.g., ID, name, CSS selector, or XPath).

2. Use JavaScript to simulate the click action on the button element.

Here's an example using Python with the Selenium WebDriver:

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
from selenium.webdriver.common.action_chains import ActionChains

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

# Navigate to the page containing the AJAX button
driver.get("https://example.com")

# Locate the AJAX button element
button = driver.find_element(By.ID, "ajaxButton")

# Click the AJAX button using JavaScript
driver.execute_script("arguments[0].click();", button)

Alternatively, you can use the ActionChains class to perform a right-click and then a left-click sequence, which can sometimes simulate a button click:

from selenium.webdriver.common.action_chains import ActionChains

# Locate the AJAX button element
button = driver.find_element(By.ID, "ajaxButton")

# Perform a right-click and then a left-click sequence
action = ActionChains(driver)
action.context_click(button).perform()
action.click(button).perform()

Remember to replace "https://example.com" and "ajaxButton" with the actual URL and element identifier of the page and button you're working with.

Keep in mind that these methods may not work for all AJAX buttons, as some buttons may use more complex JavaScript events or require additional steps to be executed before the click action can be performed. In such cases, you may need to inspect the button's JavaScript code and replicate the necessary steps in your Selenium script.

The term "public" should be understood to mean open proxy servers. That is, they can be used by all users without exception. They can be insecure and are often quite overloaded, so the connection speed or response time when using public proxies can be very slow.

To set up a proxy on your computer, you need to go through a simple procedure. If we're talking about Windows 10, you'll first need to open the "Settings" application and the "Network and Internet" section. Here, after opening the "Proxy Server" tab, find the column "Manual proxy server setup" just to the right and move the switch to the "On" position. Enter the IP address and the proxy port in the specified fields and click "Save".

Under such parsing we mean the collection of keywords from services such as Yandex Wordstat. These data will later be required for SEO-promotion of the site. The resulting word combinations are then integrated into the content of the resource, which improves its position in SERPs on a particular topic.
