Question

Hi Im trying to develop a C# program to scrape the urls of flash movies on a website, this is the code im trying to parse

flashvars="file=http://cache01-videos02.myspacecdn.com/24/vid_878ccd5444874681845df39eb3f00628.flv"/>

the closest I got using regex was this expression

file=http://[^/]+/(.*)flv

However it outputs with the file= portion, How do I filter out the file= part?

Answer 1

I think you need this:

var url=@"flashvars=""file=http://cache01-videos02.myspacecdn.com/24/vid_878ccd5444874681845df39eb3f00628.flv""";
        var match = Regex.Match(url, @"file=(?<flashurl>http://[^/]+/(.*)flv)");
        var scrapedurl = match.Groups["flashurl"].Value;

The (?/<flashurl>...) part will extract the part between the parentheses and give it the name “flashurl”;
