Have you tried anything without DLL? If not,why? If yes, where is the code? What are the issues?

I have tried by using regex (Regular expression)for replacing contents.but for selecting particular <Body> tag i have used HTMLAgility pack dll.

Use a regex:

<body>.*</body>

Should do it.

Using Regex will definitely not work.
HTML is not a regular language.

Why don't you want to use a library like HTML agility pack?

BillWoodruff 21-Nov-14 10:06am

Have you personally tried using the RegEx suggested by OriginalGriff on a string containing the text of a properly formatted HTML page ? If not, why are you claiming it will not work ?

Maciej Los 21-Nov-14 11:30am

HTML is not a regular language. Are we talking about the same language?

I tried although I know it will fail...

OriginalGriff 21-Nov-14 10:26am

Strangely, I tried as well before I posted this - with the source of a Codeproject page, in Expresso.

To my complete lack of surprise, it worked perfectly...

BillWoodruff 21-Nov-14 12:36pm

It worked because you expected it to work.

OriginalGriff 21-Nov-14 12:50pm

That's getting a bit too quantum for me...:laugh:

BillWoodruff 21-Nov-14 13:16pm

Well, what else could I have said given the blood-oath that binds me to never mention your paranormal powers ?

BillWoodruff 21-Nov-14 12:36pm

It failed because you expected it to fail.

I have tried by using this regex function but in which I have got only <body>#information</body>.but issue is that All other tags has been removed from this file ,only information has got.
Actually i want full <Body>with all tags .</body>

OriginalGriff 24-Nov-14 5:06am

Then what you are feeding into the regex is not what you think: it is - literally - <body>#information</body> not <body>Hello, and welcome to my website...</body>

You need to look at where you are getting the information from, and exactly what it contains rather than trying to process it at this stage.

Hi OriginalGriff,
now ,I have tried by using another way open html file as a read mode,following logic i have used.
FileStream fstream = File.OpenRead(first);

byte[] Filecontent = new byte[fstream.Length];
fstream.Read(Filecontent, 0, (int)fstream.Length);
fstream.Close();

string StringOutput = System.Text.Encoding.UTF8.GetString(Filecontent);
int bodyBegin = StringOutput.IndexOf("<body>") + "<body>".Length;
int bodyEnd = StringOutput.IndexOf("</body>");
int bodyLength = bodyEnd - bodyBegin;

string sbody = StringOutput.Substring(bodyBegin, bodyLength);

I Isuue is resolved now.

Thanks to all.....

Hi,

you could extract the body content like this:

C#

string ExtractBody(string html)
{
    int bodyBegin = html.IndexOf("<body>") + "<body>".Length;
    int bodyEnd = html.IndexOf("</body>");
    int bodyLength = bodyEnd - bodyBegin;

    return html.Substring(bodyBegin, bodyLength);
}

Happy coding,
Stephan
