In the HTML below:
<a href="link1.php">1</a><a href="link2.php">2</a><a href="link3.php">3</a>
How do I extract link1.php,link2.php,link3.php and push them into an array using regex? (There could be N number of <a> tags in the text)
[Edit] I'm aware the regex for this is something like href="([^"])*". But I'd like to know how to go about this in Actionscript. Specifically, how can they be pushed into an array in Actionscript?
var str:String = '<a href="link1.php">1</a><a href="link2.php">2</a><a href="link3.php">3</a>';
var result:Array = str.split(/<a[^>]*href="([^"]*)".*?>.*?<\/a>/);
for (var i:int = 1; i < result.length; i += 2) {
trace(result[i]); // link1.php, link2.php, link3.php
}
<a[^>]*href="([^"]*)"
The regex href="([^"])*" should work most of the time. It'd capture into \1. You may have to use this in a loop, and you may have to escape the ".
Are you sure you want to use regex to parse html?
How about something like:
var anchors:String = '<a href="link1.php">1</a><a href="link2.php">2</a><a href="link3.php">3</a>';
var html = new XML('<p>' + anchors + '</p>');
var links:Array = [];
for each(var a:XML in html.a)
links.push(String(a.@href));
html..a instead of html.a inside for each to access all the descendants that are anchors.Using RegExp.exec() will return an Object that you can access by index, like an array.
