Extract hyperlinks from javascript strings.

link_extractor

This is a simple node.js module for extracting hyperlinks from javascript strings.

It currently understands three different linking strategies:

• HTML Links.
  • <a href="http://example.com/">Test</a>
• BBCode Links.
  • [url=http://example.com/]example[/url]
  • [link=http://example.com/]example[/link]
• Links surrounded by [].
  • [http://example.com This is my title]

Installation

You should be able to install this module by executing:

$ npm install link_extractor

Failing that you can clone the repository, and load the code via:

require( "./link_extractor" );

Examples

 //
 // Use the node.js assert module to validate our code.
 //
 var c      = require( "link_extractor" );
 var assert = require('assert');

 //
 // Did we find one link from the given string?
 //
 result = c.extract( '<p>This is a <a href="http://example.com/">test</a> ... </p>' );
 assert( result.length == 1 )

 //
 //  Is the single result the correct one?
 //
 assert(result[0]['text'] == "test",
        "The first link has the correct anchor-text" )
 assert(result[0]['link'] == "href=\"http://example.com/\"",
        "The first link has the correct URL" )
