How to use it
- Paste text, markup, or a domain list into the text area.
- Select Extract and Process Domains.
- Check the unique-domain count.
- Review each identified host, derived extension, and syntax badge.
- Copy the output table if you need the extracted inventory.
The code does not parse the HTML DOM or distinguish links, text, scripts, internal hosts, or external hosts.
What is the purpose of the tool
This page helps developers and content teams collect domain-like strings that appear inside pasted markup.
It scans the raw source text, deduplicates matches, and reports a basic syntax result for each.
What parameters it generates in output
Processed Inventory reports the number of unique domain-like strings found. # numbers each output row.
Identified Domain / Host is the lowercase matched string. TLD / Extension joins every label after the first dot. Syntax Status shows Valid RFC when every label passes the page's length and edge-character pattern, otherwise Invalid Syntax.
FAQs related to that specific tool
Does it read anchor href attributes specifically?
No. It searches the entire pasted string with one regular expression.
Are internal and external domains labeled?
No. The output does not compare hosts or classify link scope.
Can domains inside scripts or comments match?
Yes. Any matching text can be extracted regardless of HTML context.
Does malformed HTML prevent extraction?
No. The code does not require valid markup.
Are repeated hosts removed?
Yes. Matching strings are lowercased and deduplicated.
Does it fetch HTML from a URL?
No. Markup must be pasted into the text area.
