Writing some ASP code and I need to take a string, representing a phone
number, and strip out some characters, namely spaces, brackets and hyphens.
I could write
pNum=replace(pNum," ","")
pNum=replace(pNum,"-","")
pNum=replace(pNum,"(","")
pNum=replace(pNum,")","")
....but that's a bit of a pain. Especially since I'll be doing similar
replacements with other data and may have to strip out a larger number of
characters.
I know that this can be done with regular expressions, but all the examples
I see online are several lines in length. Isn't there a simple way to just
say "remove any of these" or "replace any of these with nothing" in a single
line of code?

If you only want digits then here's one approach.
<html>
<head>
<title>numbonly.htm</title>
<script type="text/javascript">
function numbonly(that) {
var numb = that.value;
var what = "";
for (var i=0; i<numb.length; i++) {
var byte = numb.substr(i,1);
if (byte >= "0" && byte <= "9") what += byte;
}
that.value = what;
}
</script>
</head>
<body>
<center>
<form name="form1">
<input type="text" name="numb" size="20" maxlength="20"
value="(123) 456-7890" onblur="numbonly(this)">
</form>
</center>
</body>
</html>

As already stated no there isn't but yet there is; use a function (the art
of abstraction is often
lost in the serial nature of ASP script).
Have the following function (and a range of other useful utilities) in an
ASP page that is included in the pages where you need them:-
Function RegExReplace(rsInput, rsPattern, rsReplace)
Dim oRegEx
Set oRegEx = New RegExp
oRegEx.Pattern = rsPattern
oRegEx.Global = True
RegExReplace = oRegEx.Replace(rsInput, rsReplace)
End Function
Now your stated case becomes:-
pNum = RegExReplace(pNum;" |-|\)|\)","")
and your other similar cases will be simply a matter of varing the pattern.

Bob, it's very rare, but this time you're wrong. See the message in
this thread by Anthony Jones. A Regular Expression is ideal for this
problem.

Oh wait! I AM wrong. Nested Replace statements will accomplish this on a
single line.
This pNum=replace(pNum," ","")
pNum=replace(pNum,"-","")
pNum=replace(pNum,"(","")
pNum=replace(pNum,")","")
can be done by:
pnum=replace(replace(replace(replace(pNum,")",""), "(",""),"-","")," ","")

What are you talking about? Please quote the message to which you are
replying.
Oh wait, I remember now.
A Regular Expession may be ideal for this problem, but a regular expression
also takes at least 3 lines to use, one to instantiate the regexp object,
one to initialize the pattern, and one to execute the replace statement. So
it is not the answer to the question you asked.

execute function in vbs or js:
<%
pNum = pNumReplace(pNum)
%>
define in jscript:
<script runat=server language=jscript>
function pNumReplace(x) { return x.replace(/[ -()]+/g,'') }
</script>

Maybe I'm reading it wrong, but shouldn't that be:
pNum = RegExReplace(pNum," |-|\(|\)","")
i.e.: " |-|\(|\)" instead of " |-|\)|\)"
The original example has two closing brackets instead of one opening
and one closing bracket.
And shouldn't there be a comma after pNum instead of a semicolon? i.e.: " |-|\(|\)" instead of " |-|\)|\)"

Your quite right thats a typo.
Should read:-
pNum = RegExReplace(pNum," |-|\(|\)","")
Another option would be:-
Function CharReplace(rsInput, rsChars, rsReplace)
Dim i
CharReplace = rsInput
For i = 1 To Len(rsChars)
CharReplace = Replace(CharReplace, Mid(rsChars, i, 1), rsReplace)
Next
End Function
pNum = CharReplace(pNum, " -()", "")
Personally I prefer the RegExp solution since I don't like to create a
destory strings if I can help it. But the above may perform better for
short rsChars.
My main point is that there is nearly all ways a single line solution.
Create a function.
