Search among all non-blanks in string

Hi Experts,

I attempt to make a search in records containing both blank and linebreak characters. The basic InStr("str", search) only return results from the first line in the record, not recoqnizing anything under that.
Forums point out that RegExp could rid the record of unwanted blanks, so the search string applies to all non-blanks of the InStr, but so far this method eludes me. Also I need the code to ignore case.
Applied the following code and variants, but that simply fails, returning no results whatsoever, so what do I miss?


<table>
<%
Dim re, targetString, colMatch, objMatch

do while not McalRec.EOF
Set re = New RegExp
With re
  .Pattern = "\s"
  .Global = True
  .IgnoreCase = True
End With
targetString = re.Test(McalRec("notat"))

if Instr(targetString, SearchMCal) then
countallMcal = countallMcal + 1

                        response.write("<tr align='left' valign=top style='color:#FF0000;'>" &_
                        "<td style='color:#FF0000;'>" & McalRec("notat") & "</td>" &_
                        "<tr><td colspan='15'><hr></td></tr>")
else
end if
McalRec.movenext
loop
%>
</table>

try using
^\s*$

Open in new window

as your pattern

Explanation:

^ is the beginning of string anchor
$ is the end of string anchor
\s is the whitespace character class
* is zero-or-more repetition of
In multiline mode, ^ and $ also match the beginning and end of the line.

Hi Big Monty,

thank You for getting back to me:)

I put in Your pattern, but still no luck. Wonder if I understand the use of RegExp fully - are the targetString fx. placed correctly under the End With?

- or, btw, should I use regexp instead of instr in the if-then part??

fair warning, I am NOT a RegExp expert, I've only dabbled in them with url rewriting :)

Your targetString variable is in the write place, but doesn't look right. try changing

targetString = re.Test(McalRec("notat"))

targetString = McalRec("notat")
matchFound = re.test( targetString )

then change your if statement to

if matchFound then

here's a pretty good reference page for regexp's:

I think you want to do a Regex.Replace, like is done here:

Edit: re-reading the question, I think I'm wrong about that. I'll have another think about it.
