Powershell script to collect data from text file

i have a list that looks like the following: [name] value01=100 value02=K_ [/name] [name] value01=100 value02=__ [/name] [name] value01=100 value02=K_ [/name] etc... in value02 there sometimes is a 'K' to indicate the start of a group. the group goes on through all the next [name]...[/name] packages until before the next 'K' appears in a packet which is at random. a sum needs to be created from all collected value01 per group and put the result into an array. so in the above case the result would be array01 200 array02 100 please let me know if you can do this
