macro to search in parent directory

Hi All,

Could anyone please help me in coding the below. We have a requirement to not to use IP address in the files (*.xsl,*.xml,*.xsd and *.wsdl) under one folder. The folder can have subdirectories and files. The macro should search for the ip address pattern(eg:0.0.0.0, any four numbers seperated by 3 dots) in the files under all directories and subdirectories. If there is a match found. The Cells(1,1) should show the details like
Ip address found '0.0.0.0' in the folder c:\Folder\Status.xsl at line number 18. And the subsequent enties should continue from Cells(2,1). Please see the attached zip file with a sample folder and the xl sheet.
