Usage Example

Suppose you have a piece of HTML code that contains multiple links:

<p>Visit our official website: <a href="https://www.example.com">Example Website</a>.</p>
<p>Download file: <a href="ftp://ftp.example.com/file.zip">File Download</a>.</p>
<p>Contact us: <a href="mailto:info@example.com">Send Email</a>.</p>
<p>Blog posts: <a href="https://blog.example.com/post-1">Post One</a>, <a href="http://blog.example.com/post-2">Post Two</a>.</p>
<p>This is an invalid link: <a href="invalid-link">Invalid</a>.</p>

Example input data:

<p>Visit our official website: <a href="https://www.example.com">Example Website</a>.</p>
<p>Download file: <a href="ftp://ftp.example.com/file.zip">File Download</a>.</p>

Components of a URL

A complete URL typically consists of the following main parts:

• Scheme: Specifies the resource access method, such as http://, https://, ftp://, mailto:, etc.
• Host: Identifies the host providing the resource, which can be an IP address or a more common domain name, such as www.example.com.
• Port: Optional, used to specify a specific port number for the server, such as :8080.
• Path: Specifies the exact location of the resource on the server, such as /directory/file.html.
• Query: Optional, used to send additional information to the server, starting with a question mark ?, with key-value pairs connected by &, such as ?name=value&id=123.
• Fragment: Optional, starting with a hash mark #, pointing to a specific location within the document, such as #section-a.

Understanding these components of a URL helps to better understand the tool's extraction logic and the structure of URLs.
