🚀 Usage

Basic RSS Feed Parsing

use RssFeed;

// Parse RSS feed
$feed = RssFeed::RssFeeds('https://example.com/feed.xml');

// Get feed items
foreach ($feed->get_items() as $item) {
    echo $item->get_title();
    echo $item->get_description();
}

Full-Text Content Extraction

use Kalimeromk\Rssfeed\FullTextExtractor;

$extractor = app(FullTextExtractor::class);

// Extract from URL
$result = $extractor->extract('https://example.com/article');

if ($result['success']) {
    echo $result['title'];
    echo $result['content'];
    echo $result['author'];
    echo $result['language'];
}

// Extract from HTML string
$result = $extractor->extractFromHtml($html, 'https://example.com/article');

Process Feed with Full Content

use RssFeed;

$items = RssFeed::parseRssFeeds('https://example.com/feed.xml');

foreach ($items as $item) {
    echo $item['title'];
    echo $item['content']; // Full article content
    echo $item['author'];
    echo $item['language'];
}

Clean Text Extraction (No HTML)

$items = RssFeed::parseRssFeedsClean('https://example.com/feed.xml');

foreach ($items as $item) {
    echo $item['content']; // Plain text, no HTML
}

Generate Feed Output

use Kalimeromk\Rssfeed\Services\FeedOutputService;

$outputService = app(FeedOutputService::class);

// RSS 2.0
$rss = $outputService->toRss($feedData);

// Atom
$atom = $outputService->toAtom($feedData);

// JSON Feed
$json = $outputService->toJson($feedData);

Image Handling

// Extract images from feed item
$images = RssFeed::extractImagesFromItem($item);

// Save images to storage
$savedImages = RssFeed::saveImagesToStorage($images, $model);

HTML Sanitization

use Kalimeromk\Rssfeed\Services\HtmlSanitizerService;

$sanitizer = app(HtmlSanitizerService::class);

// Basic sanitization
$clean = $sanitizer->sanitize($html);

// Remove inline styles
$noStyles = $sanitizer->sanitizeWithoutStyles($html);

// Strip all HTML
$text = $sanitizer->stripAllTags($html);

🔧 Advanced Usage

Custom Site Configuration

Create custom extraction rules in site_config/custom/{hostname}.txt:

# Example: example.com.txt
body: //article[contains(@class, 'main-content')]
title: //h1
author: //span[@class='author-name']
date: //time[@pubdate]

# Remove unwanted elements
strip_id_or_class: ads,comments,sidebar
strip: //div[@class='donation-form']

Domain-Specific Selectors

Add to config/rssfeed.php:

'content_selectors' => [
    'example.com' => '//div[@class="article-content"]',
    'news.example.com' => '//article[contains(@class, "story")]',
],

Content Cleanup Rules

'remove_selectors' => [
    '.donation-form',
    '.share-buttons',
    '.comments',
    '.advertisement',
],
