I have some log like

> (2)au(8)download(13)windowsupdate(3)com(0)  
> (8)clients3(6)google(3)com(0)  
> (3)v10(10)vortex-win(4)data(9)microsoft(3)com(0)

Now i want it look like

> [au.download.windowsupdate.com](http://au.download.windowsupdate.com)  
> [clients3.google.com](http://clients3.google.com)  
> [v10.vortex-win.data.microsoft.com](http://v10.vortex-win.data.microsoft.com)

How can do it. Thank!
