I'm inputting data into a sql database. The problem is this: the data is spreadsheet data for registered users.... So, I don't need it to wipe out the spreadsheet data, just strip it of all other data. Anybody have the cleaning code for this? Thanks, Chris.

Here is a function that'll strip all your HTML from a string.  So pass the string from your database to this function and it'd return it without the HTML.

http://www.4guysfromrolla.com/webtech/042501-1.shtml

 

Function stripHTML(strHTML)

'Strips the HTML tags from strHTML using split and join
 

  'Ensure that strHTML contains something

  If len(strHTML) = 0 then

    stripHTML = strHTML

    Exit Function

  End If
 

  dim arysplit, i, j, strOutput
 

  arysplit = split(strHTML, "<")

 

  'Assuming strHTML is nonempty, we want to start iterating

  'from the 2nd array postition

  if len(arysplit(0)) > 0 then j = 1 else j = 0
 

  'Loop through each instance of the array

  for i=j to ubound(arysplit)

     'Do we find a matching > sign?

     if instr(arysplit(i), ">") then

       'If so, snip out all the text between the start of the string

       'and the > sign

       arysplit(i) = mid(arysplit(i), instr(arysplit(i), ">") + 1)

     else

       'Ah, the < was was nonmatching

       arysplit(i) = "<" & arysplit(i)

     end if

  next
 

  'Rejoin the array into a single string

  strOutput = join(arysplit, "")

  

  'Snip out the first <

  strOutput = mid(strOutput, 2-j)

  

  'Convert < and > to &lt; and &gt;

  strOutput = replace(strOutput,">","&gt;")

  strOutput = replace(strOutput,"<","&lt;")
 

  stripHTML = strOutput

End Function

I think it would be best if you used Regular Expressions.

Here's something i wrote on the fly, i hope it works.
using System.Text;

using System.Text.RegularExpressions;
 

string input;

string output = Regex.Replace(input, "<[a-zA-Z]{1}.*>", "");

output = Regex.Replace(output, "</[a-zA-Z]{1}.*>", "");
