here i want to create sequence no. with every paragraph line

..

output like...

<p local_id = P-100>aaaaaaaaaaaaaaaaaaaaaaaaa<\p>
<p local_id = P-101>bbbbbbbbbbbbbbbbbbbbbbbbb<\p>
<p local_id = P-102>vvvvvvvvvvvvvvvv<\p>



and show in richtextbox control..but he didn't work.

here is my code:-

richTextBox1.LoadFile(filepath,RichTextBoxStreamTy pe.RichText);
string inputstring = richTextBox1.Text;
StringBuilder sb = new StringBuilder(inputstring);
sb.Insert(0, "");
sb.Replace("\n", "" + "\n" + "");
sb.Replace("", "");
sb.Append("");
sb.Replace("", "");
sb.Replace("\n\n", "\n");
sb.Replace("\n\n", "\n");
sb.Replace("\n\n", "\n");
sb.Replace("\n\n", "\n");
sb.Replace("\n\n", "\n");
sb.Replace("\n\n", "\n");
richTextBox1.Text = sb.ToString();

Wow, weirdest code sample ever.

You do realise that the first 4 lines on your StringBuilder do absolutely nothing (one inserts nothing at the start, then you replace a line break with empty strings, plus a line break, then replace nothing with, err, nothing, and finally append, err, nothing... oh, and then replace nothing with nothing again.)

And secondly your code sample appears to have nothing to do with the XML (or rather invalid XML) that you showed in the first part?

If you want to increment a number in C#, then surely int i = 1; i++; would do it...
