METHOD:  object.Execute
Implemented in version 5.0
 
object.Execute (TargetString)
 
The Execute method is used with a RegExp object variable to look for a search string pattern (also known as a regular expression) inside a target string.
 
There is one mandatory argument, the target string to be searched. The search string pattern (regular expression) is declared using the Pattern property.
 
Each time a match is made (i.e., the search pattern is found inside the target string), a Match object is created and added to a Matches collection. Note that a match does not have to occur. Therefore the Execute method can return a Matches collection that is empty, or that contains one or more, objects.
 
Code:
<%
'this sub finds the matches
Sub RegExpTest(strMatchPattern, strPhrase)
    'create variables
    Dim objRegEx, Match, Matches, StrReturnStr
    'create instance of RegExp object
    Set objRegEx = New RegExp
 
    'set the pattern
    objRegEx.Pattern = strMatchPattern
 
    'create the collection of matches
    Set Matches = objRegEx.Execute(strPhrase)
 
    'print out all matches
    For Each Match in Matches
        strReturnStr = "Match found at position "
        strReturnStr = strReturnStr & Match.FirstIndex & ". Match Value is `"
        strReturnStr = strReturnStr & Match.value & "'."
        'print
        Response.Write(strReturnStr & "<BR>")
    Next
End Sub
 
'call the subroutine
RegExpTest "is.", "Is1 is2 Is3 is4"
%>
 
Output:
Match found at position 4. Match Value is `is2'.
