RE: [flexcoders] Using Flex to extract a phrase from a text file

[Alex Harui]

How about:

 

var pos:int = randomText.indexOf('.swf');

var url:String = randomText.substring(0, pos + 4);

pos = url.lastIndexOf('');

url = url.substring(pos + 1);

I have one text file with about 100 lines of random text. Somewhere on
the file, there is an URL for a SWF. The url has the .swf word in it,
and it's between 's . The format of the file can change over time,
and there is only one SWF file on the text file. 

I need to find the best algorithm to extract the URL from the text
file. Any suggestions?

Thanks, 

João Saleiro

Regexp will save the world, one text document at a time.

var s:String = some long \text\ goes in here and a swf url 
\one/two/three.swf\ went in there;
var re:RegExp = new RegExp('([^]+.swf)','i');
var m:Array = s.match(re);
  
trace(m[1]); // one/two/three.swf

Cheers,
Adam
