Question

I am trying to extract the information after a specific string int a file. Following is the segment that contains the string:

<Plane TheZ="0" TheT="0" TheC="0" DeltaT="0.2056"/><TiffData FirstT="0" FirstZ="0"

The information I am trying to extract is 0.2056 which always follows DeltaT="
I want this search to be as quick as possible. So I am wondering what is the best way to do it?

Answer 1

You could use a regular expression

var regex = new Regex(@"DeltaT=""(.*?)""");
foreach (Match m in regex.Matches(inputText))
{
    Console.WriteLine(m.Groups[1].Value);
}

However, since it looks like it might be X(HT)ML, prefer Linq-To-Xml if possible
