HTML Varlık Kod Çözücü

// html_entity_decode() - standard decoding
$decoded = html_entity_decode($encoded, ENT_QUOTES, 'UTF-8');
// Decodes: < > & " ' and all HTML entities

// htmlspecialchars_decode() - decodes only basic entities
$decoded = htmlspecialchars_decode($encoded, ENT_QUOTES);
// Decodes: < > & " ' only

// Example: Processing API response
$apiData = json_decode($response, true);
$title = html_entity_decode($apiData['title'], ENT_QUOTES, 'UTF-8');

// Safe decoding using DOMParser
function htmlDecode(str) {
    const parser = new DOMParser();
    const doc = parser.parseFromString(str, 'text/html');
    return doc.documentElement.textContent;
}

// Using textarea element (alternative)
function htmlDecode(str) {
    const textarea = document.createElement('textarea');
    textarea.innerHTML = str;
    return textarea.value;
}

// WARNING: Never use innerHTML with untrusted data
// element.innerHTML = encoded; // DANGEROUS if untrusted

import html

# html.unescape() - decodes all HTML entities
decoded = html.unescape(encoded)
# Decodes: < > & < < etc.

# Example: Processing API response
import json
data = json.loads(response)
title = html.unescape(data['title'])

# BeautifulSoup (for HTML parsing with auto-decode)
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_content, 'html.parser')
text = soup.get_text()  # Automatically decodes entities

import "html"

// html.UnescapeString() - decodes HTML entities
decoded := html.UnescapeString(encoded)
// Decodes: < > & " ' etc.

// Example: Processing XML feed
type RSSItem struct {
    Title       string `xml:"title"`
    Description string `xml:"description"`
}
// Decode after parsing
item.Title = html.UnescapeString(item.Title)

// Apache Commons Text (recommended)
import org.apache.commons.text.StringEscapeUtils;
String decoded = StringEscapeUtils.unescapeHtml4(encoded);
// Decodes all HTML4 entities

// Example: Processing API response
import com.google.gson.Gson;
ApiResponse response = gson.fromJson(json, ApiResponse.class);
String decodedTitle = StringEscapeUtils.unescapeHtml4(response.getTitle());

// Jsoup (for HTML parsing with auto-decode)
import org.jsoup.Jsoup;
String decoded = Jsoup.parse(encoded).text();

require 'cgi'

# CGI.unescapeHTML() - decodes HTML entities
decoded = CGI.unescapeHTML(encoded)
# Decodes: < > & " etc.

# Nokogiri (for HTML parsing with auto-decode)
require 'nokogiri'
doc = Nokogiri::HTML(html_content)
text = doc.text  # Automatically decodes entities

# Example: Processing RSS feed
require 'rss'
rss = RSS::Parser.parse(feed_content)
rss.items.each do |item|
  title = CGI.unescapeHTML(item.title)
end
