Extracting data from string

Report · Apr 19, 2007

Can anyone point me in the right direction as to how URL's can be extracted from a string?
Or at least find the start and end positions...
EG:
I want to get the URL's from the "a href"'s...
String- "The quick brown fox jumps over the lazy dog, <a href=" http://www.example1.com">click here</a>. The quick brown fox jumps over the lazy dog, <a href=" http://www.example2.com">click here</a>.".

Hi,

You can do this by using the "anchors" object in "Javascript".. Below is the Sample Code..

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns=" http://www.w3.org/1999/xhtml">
<head>
<script language="javascript">
function fnCheckAnchors()
{
for (var i=0;i<document.anchors.length;i++)
{
alert(document.anchors.item(i));
}
}
</script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<form name="form" action="" method="post" onsubmit="fnCheckAnchors();">
<a name="1" href=" http://www.yahoo.com">Yahoo</a><br />
<a name="2" href=" http://www.google.com">Google</a><br />
<a name="3" href=" http://www.altavista.com">Altavista</a><br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>

Thanks for taking the time to reply - much appreciated. Unfortunately this isn't what I need.

I probably wasn't clear enough in the original post, allow me to ellaborate:
These data strings will be coming from a database.
Basically the URL's that i want to extract are old and need to be replaced with new URLS... because the links have been inserted using dynamic content, I can't just do a simple replace() because I don't / wont know what the links are... I need something that will detect where the "<a href=" is and be able to determine how long that href value is and put that into a variable.
