Language Reference Version 5 |
Description
Replaces text found in a regular expression search.
Syntax
object.Replace(string1, string2)The Replace method syntax has these parts:
Part Description object Required. Always the name of a RegExp object. string1 Required. String1 is the text string in which the text replacement is to occur. string2 Required. String2 is the replacement text string.
Remarks
The actual pattern for the text being replaced is set using the Pattern property of the RegExp object.The Replace method returns a copy of string1 with the text of RegExp.Pattern replaced with string2. If no match is found, a copy of string1 is returned unchanged.
The following code illustrates use of the Replace method:
In addition, the Replace method can replace subexpressions in the pattern. The following call to the function shown in the previous example swaps each pair of words in the original string:Function ReplaceTest(patrn, replStr) Dim regEx, str1 ' Create variables. str1 = "The quick brown fox jumped over the lazy dog." Set regEx = New RegExp ' Create regular expression. regEx.Pattern = patrn ' Set pattern. regEx.IgnoreCase = True ' Make case insensitive. ReplaceTest = regEx.Replace(str1, replStr) ' Make replacement. End Function MsgBox(ReplaceTest("fox", "cat")) ' Replace 'fox' with 'cat'.
MsgBox(ReplaceText("(\S+)(\s+)(\S+)", "$3$2$1")) ' Swap pairs of words.
