Retrieving the value in the embed html

[jknascrimz]

hi, Iam working with asp.net with c# in VS.Net 2008. And in a task of mine I am fetching a data from the DB which contains a embed html for eg: " <object width="230" height="155"> <param name="movie" value="http://www.youtube.com/v/Ab9kmqBmhXc&hl=en&fs=1&"></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="http://www.youtube.com/v/Ab9kmqBmhXc&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="230" height="155"></embed></object>" In this fetched data i need to get only the value="http://www.youtube.com/v/Ab9kmqBmhXc&hl=en&fs=1&" or src="http://www.youtube.com/v/Ab9kmqBmhXc&hl=en&fs=1&" I need only the value or src(i.e) the url Bcoz i need to use that Url for some other purposes also. Kindly help me in getting the value. Thanks in advance.

Use regular expressions to filter it. Please google for regular expressions patterns that can search url including query strings.

Thanks For ur Information & I already Googled but not yet derived any suitable solution.

2 ways to do this. 1) Regular expression 2) Loading the content into XmlDocument and using XPath to query. 2nd method will be easy to implement. Sample XPath query, /object/param[@name='movie'] This will give all param elements which have a name attribute with value movie. From this, you can easily get value of attribute value.

Thanks for ur kind reply, I need the solution in the 1st way i.e Using RegularExpression coz am working with C# + asp.net. In the regex, it is possible to find the keyword value or src but what i need is url that follows these value or src. I tried for it but failed to proceed further in getting that specified Url.

Check this[^]

[N a v a n e e t h]

Try this.

bool TryGetVideoUrl(string input, out string url)
{
url = string.Empty;
string pattern = "embed.src=\"(?<video>[^\"]*)\"";
Match match = Regex.Match(input, pattern, RegexOptions.IgnoreCase);
if (match != null)
{
url = match.Groups["video"].Value;
return true;
}
else
return false;
}

Use it like,

string url;
if (TryGetVideoUrl(input, out url))
{
// you got the url. It will be in variable url
}
else
{
// not found
}
