need help with a regular expression replace command

[Danny]

I need an asp command to strip out from a string all extra punctuation such
as apostrophe, comma, period, spaces dashes, etc etc and just leave the
letters.

Can anybody give me some ideas?

Thanks

Yes. It's easier to match what you want and just dump the rest. This
example returns A-Z regardless of case or in your terms, "just the letters."

<%@ Language=VBScri pt %>
<%
Option Explicit
Response.Buffer = True

function getAlpha(str)
dim re, match, matches, reStr
set re = New RegExp
re.Pattern = "[a-z]+"
re.IgnoreCase = True
re.Global = True
set matches = re.Execute(str)
for each match in matches
reStr = reStr & match.value
next
getAlpha = reStr
end function

Response.Write( "Result: " & getAlpha("AaB5b !'C,*cD/d\Ee"))
%>

Response:
Result: AaBbCcDdEe

HTH...

I don't think so,
the replace function is much quicker than matching and a loop:

function getAlpha(str)
dim re
set re = New RegExp
re.Pattern = "[^a-z]+"
re.IgnoreCase = True
re.Global = True
getAlpha = re.replace(str, "")
end function

Response.Write "Result: " & getAlpha("AaB5b !'C,*cD/d\Ee")

JScript:
return myString.replac e(/[^a-z]/gi,"")

vbscript:
Use the Replace function and the RegExp object to do the same.

I use a function for that. There might a slicker way to do it, but this is what I came up with. You can replace each puncuation mark with just an empty string "" instead of the encoding.

Function EncPunc(checkPu nc)
strTmp = checkPunc
strTmp = Replace(strTmp, "'","%39")
strTmp = Replace(strTmp, "%","%25")
strTmp = Replace(strTmp, "&","%26")
strTmp = Replace(strTmp, "#","%23")
strTmp = Replace(strTmp, ";","%3B")
strTmp = Replace(strTmp, "/","%2F")
strTmp = Replace(strTmp, "?","%3F")
strTmp = Replace(strTmp, ":","%3A")
strTmp = Replace(strTmp, "@","%40")
strTmp = Replace(strTmp, "=","%3D")
strTmp = Replace(strTmp, "<","%3C")
strTmp = Replace(strTmp, ">","%3E")
strTmp = Replace(strTmp, """","%22")
strTmp = Replace(strTmp, "{","%7B")
strTmp = Replace(strTmp, "}","%7D")
strTmp = Replace(strTmp, "|","%7C")
strTmp = Replace(strTmp, "\\","%5C")
strTmp = Replace(strTmp, "^","%5E")
strTmp = Replace(strTmp, "~","%7E")
strTmp = Replace(strTmp, "[","%5B")
strTmp = Replace(strTmp, "]","%5D")
strTmp = Replace(strTmp, "`","%60")
EncPunc = strTmp
End Function

you are mistaken, this is not javascript, but vbscript

Yes, there is a much easier wa to do HTML entity, unfortunatly as far as I
can tell regexps in VB are severely impared!!!
The easy way to do this is to match the char with a regular expresion and
then get the numeric value for the char.
In VB it would look something like
dim reg1 as RegExp
set reg1= new RegExp
reg1.global = true
reg1.pattern="([^a-zA-Z0-9\s])"
text=reg1.repla ce(text,"&" & Asc("$1") & ";"

Unfortunatley in VB you can not pass submatches to a funtion. Submatches
only work inside the expression.
If anyone knows how to pass submatches to a function in a VB RegExp please
let me know.
For now I just call external Perl scripts from VB

by the way, the above in Perl looks like this
$text=~s/([^a-zA-Z0-9\s])/"&".ord($1) .";"/ge;

Aside from being brief, it works!!!
And if we want to check to make sure entities like $ do not get encoded we
can pass to a function that handles this
$text=~s/([^a-zA-Z0-9\s])/encodeHTMLentit ies($1)/ge;
