regex help

[uglyeyes]

no only the text i have provided you is valid. the content of the entire csv files has text like ----1---- my contents.. ----2---- my content2.. ... ... so could you please help how to extract the data i want? i have this regex that seem to work to get text between div tag

?<=\<div class=""middlead""\>).*?(?=\</div\>

but i need to get description of apple too. i tried to use below code

string fName = @"data.txt";//path to text file
StreamReader testTxt = new StreamReader(fName);
string allRead = testTxt.ReadToEnd();//Reads the whole text file to the end
testTxt.Close(); //Closes the text file after it is fully read.

        //Regex rx = new Regex(@"(?<=\\<div class=""middlead""\\>).\*?(?=\\</div\\>)", RegexOptions.Singleline);
        Regex rx1 = new Regex(@"(?<=\\<p\\>&nbsp;&nbsp;&nbsp;\\</p\\>).\*?(?=\\</p\\>)", RegexOptions.Singleline);

            

        //MatchCollection matches = rx.Matches(allRead);
        MatchCollection matches1 = rx1.Matches(allRead);

        StreamWriter sw = new StreamWriter(@"realdata.txt");
        int count = 0;
        foreach (Match match in matches1)
        {
            sw.WriteLine(count.ToString());
            sw.WriteLine(match.ToString());

            foreach (Match match1 in matches1)
            {
                sw.WriteLine(match1.ToString());
            }
            count++;

        }
        sw.Close();


      
        
    }

but some how regex rx1 is not only giving text that i want but its doing greedy matching and try to match everything that has

could you please help as to how can i extract the description of those products.

Once again, html IS xml. Just use Linq-To-XML to parse it - using regex is a WASTE OF TIME. It's easy - really. All you have to do is man-up and do some frakking research. It's just a few lines of code.

Hi, Please use below Regex Pattern to get your result. .*?>([a-zA-Z0-9].*?)< Which will return the collection of apple red delicious banana riped banana chives fresh green chives Please let me know if you have any doubt.

not sure why my below regex fails in visual studio editor (?<=\<p\>   \</p\>\n\t+:b+).*(\n\t+:b+\<div class="central"\>) please note \t+ and :b+ are added because there is exactly 2 tab spaces and 2 white spaces in between the matching text. if I only use <p\>   \</p\>\n\t+:b+ it highlights the preceeding text of the matching text. not sure why by select between group is not working in visual studio. I am running out of ideas please help???
