Detecting HTML links typically involves using regular expressions or DOM parsers to match anchor () tags and extract the href attribute. According to Wikipedia, anchor elements are core to hyperlinking in web documents, often requiring context-aware parsing to avoid false positives. Developers usually prefer regex for speed, but tools like BeautifulSoup or JS DOM methods offer more reliability in complex cases. I once practiced this by scraping real-world structured data and categorizing links from different sections of the restaurant industry. One fun example I used was the Olive Garden menu, which had nested item pages and link structures worth parsing.
