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'.
