Remove encoding from an xml file using regular expressions

[kunguito]

Hi everyone,

I want "encoding="XX"" removed from a string and I'll be using regular expressions.Where XX could be any possible encoding: UTF-8, UTF-16, ISO...

Here is a sample:

<?xml version="1.0" encoding="UTF-8"?>

And this is how it should look like after the replacement:

<?xml version="1.0"?>

How would the pattern look like?

Note that I'm not asking how to use regular expressions but how to build a pattern.

Code snipet based on a piece of MSDN documentation.

[VBA]Set objRegExp = New RegExp

' myPattern = "encoding=" & Chr(34) & "[+]" & Chr(34)

myPattern = "encoding=" & "\w+"
'Set the pattern by using the Pattern property.
objRegExp.Pattern = myPattern

' Set Case Insensitivity.
objRegExp.IgnoreCase = True

Set objRegExp = New RegExp


' myPattern = "encoding=" & Chr(34) & "UTF-8" & Chr(34) ==> This works fine but is a subcase of what I want.
' myPattern = "encoding=" & Chr(34) & "[+]" & Chr(34) ==> jumps the test if statement below
myPattern = "encoding=" & "\w+" ==> So does that one

'Set the pattern by using the Pattern property.
objRegExp.Pattern = myPattern

' Set Case Insensitivity.
objRegExp.IgnoreCase = True

'Set global applicability.
objRegExp.Global = True

'Test whether the String can be compared.
If (objRegExp.Test(firstLine) = True) Then

'Replace the matches.
firstLine = objRegExp.replace(firstLine, "") ' Replace

End If

JScript and VBScript regex syntax appears to be different.
