About This Tool
The Client-Side Hreflang Tag Extractor parses raw HTML source markup to extract international link tags formatted with hreflang attributes (<link rel="alternate" hreflang="..." href="..." />). The extractor scans input HTML strings using regex attribute matchers, isolating language-region pairs (such as en-us, fr-fr, or x-default) alongside their destination canonical URLs. If no valid hreflang elements exist in the submitted markup, the tool outputs an immediate diagnostic message. All HTML parsing executes locally in browser JavaScript without transmitting page source or URLs across external networks.
