Can I use ReadProfileSttring in a loop?

INI File is formatted as so:
[ComputerName]
User=USERNAME
IP=IPADDRESS
Mac=MACADDRESS

How would I read each computername? The file has about 65 entries formatted as the example. I've done loops with the readline command, but I'm not exactly sure how to make the readprofile string work in a similar fashion. I want to have a variable extracted that is only one computername. Then the next time I read the file, I want the next computername, and so on.....

Thanks in advance.
