extract links from a webpage

this is useful if you decide to make a web crawler, and dont want to bother with an html parser. You have to read the body of the page into a string, and then use this regex to extract all the links.

supported link types: <img src=...<a href=...
<br /><br />String body = "..."; //body of the page<br />Matcher m = Pattern.compile("(?im)(?:(?:(?:href)|(?:src))[ ]*?=[ ]*?[\"'])(((?:http|https)(?::\\/{2}[\\w]+)(?:[\\/|\\.]?)(?:[^\\s\"]*))|((?:\\/{0,1}[\\w\\.]+)+))[\"']").matcher(body);<br />while(m.find()){<br />String absolute = m.group(2);<br />String relative = m.group(3);<br />}<br />

an absolute url is in the form of "http://something.com/blah"
a relative url is in the form of "/something/path.blee"

now you can figure out what to do with these...
