Extracting only tags from html text file
Question
I'm working on a steganography method which hides text withing html tags.
for example this tag: <heEAd> I have to extract every character within the tag and then
analyze the case of the letter if it is capital then the bit is set to 1 else 0 and I also want to check the end if it sees the matching closing /head tag
here is the code :
WebClient client = new WebClient(); String htmlCode = client.DownloadString("url"); String Tags = ""; for(int i = 0; i < htmlCode.Length; i++){ if(htmlCode[i] ='<'){ if(htmlCode[i] = '>') continue; else{ Tags += htmlCode[i]; } } }
That logic is terrible but how do I use IndexOf and lastIndexOf to get the desired
substring I tried to use that but I'm just missing something due to the lack of my knowledge about c#

I think you need to use REGEX.
I tried to do this once with Substring and i had much job. Latter i decided to use regex and it was easier than the first one.
var regex = new Regex(@"(?<=<head>).*(?=</head>)");
return regex.Matches(strInput);
