Extract first (n) number of paragraphs from a long text

Question

I have a long text from the db and I would like a method to only output the first 3 paragraphs or something like that. Its retrieved from the database and has HTML codes too. How do I go about this?

Tina Thomas · Answer

public string getSummary(string inputHTML) { string[] arrText = inputHTML.Split('
'); return arrText[0] + arrText[1]+ arr[Text2]; }

Thanks a lot Tina: Assuming I have public string getSummary(string inputHTML){ } Please help me construct that and return a string that has only the first 3 paragraphs, Thanx.

Tina Thomas · Answer

It can definitely be achieved using a simple array split.. string[] arrText = sText.Split('
'); foreach(string sExtractText in arrText) { } Or using a regular expression like this: // Regex comments .-> matches any single character except 
 // * -> matches preceeding character any number of times //$-> end of the string Regex r = new Regex(@"(.*$)", RegexOptions.Multiline); Match m; string sExtract = ""; // This gives the groups of matched strings where the processing can be done for (m = r.Match(sText); m.Success; m = m.NextMatch()) { sExtract = m.Groups[1].Value; }

Tina I think ur getting it. Do you have a method I can use? Maybe some sample code I can implement?

Tina Thomas · Answer

If the objective is to extract first n paragraphs, then extract the whole text from the database, and use a regular expression to extract the desired text.
