reg ex question

[allida77]

I am trying to pull a key value pair from the url.


<%
strQS="&p=asdf&o=asdf&page=11234&p=asdf"
Set qsRegEx = New RegExp
qsRegEx.Pattern = "&page=\d"
qsRegEx.Global = True
newstr = qsRegEx.Replace(strQS,"")
Response.Write(strQS & "<br/>")
Response.Write(newstr)
%>


The problem is how do I get "&page=" plus all the numbers after it until the next "&"? I want to pull "&page=11234" from the QueryString.

Umm, not sure if this works but, try this pattern:
&page=.&

The . character is a universal wildcard that means anything and any length until the next part in the pattern is found.

hello

not sure if this is what you meant, but can't you simply use:

Request.QueryString("page")

I am trying to remove the key-value pair from the QS I ended up using:

strQueryString = Request.ServerVariables("QUERY_STRING")

'remove page= from the querystring
Dim qsRegEx

Set qsRegEx = New RegExp
qsRegEx.Pattern = "&page=\d{" & Len(Request.Querystring("page")) & "}"
qsRegEx.Global = True
strQueryString = qsRegEx.Replace(strQueryString,"")

I tried the "." but couldnt get it to work.
