A:
in perl:
my $work_url = $original_url;
$work_url =~ s/\+/-/g;
$url = '/blog/' . do { $work_url =~ m/\bstr=([\w\-]+)\b/; $1} . '/';
works for the example given.
inspired by Ragepotato:
$new_url = '/blog/'
. sub { local $_ = shift; tr/+/-/; m/\bstr=([\w\-]+)\b/; $1 }->($orig_url)
. '/';
And an stricter, less greedy regex for Ragepotatos post, untested:
Regex.Match(input.Replace("+", "-"),@"\bstr=(.*?)&").Groups[1].Value

You're welcome. I'm sorry I don't know C#.net syntax yet or I'd be happy to post. I'm sure the regex would look similar, but the invocation..? I'll read up a bit and see if I can wing it w/o a compiler.

This might get you close.. Syntax snagged from: http://www.radsoftware.com.au/articles/regexsyntaxadvanced.aspxusing System.Text.RegularExpressions;Regex exp = new Regex( @"\bstr=([\w\+]+)\b" ); string InputText = "abc.aspx?str=blue+lagoon MatchCollection MatchList = exp.Matches(InputText); Match FirstMatch = MatchList[0]; Console.WriteLine(FirstMatch.Value);

A:
C# .NET
string input = "abc.aspx?str=blue+lagoon&id=1234";
string output = "/blogs/" + Regex.Match(input.Replace("+", "-"),@"str=(.*)&").Groups[1].Value + "/";

nicely done. Needs a word boundary on the str and a non greedy capture (.*?) don't you think?
