Compare fields and get missing?	Can't Post

Hi all,
I have a flatfile A.txt

Code

2012/11/13 20:06:11 |t112|Locations 12, 13, 14, 15|NET12/full_ddr3_2X_FV_4BD_1.qt|norway|0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15|norway22 
2012/11/14 14:23:19 |t112|Locations 0, 1, 2, 3, 4, 5, 6, 7|NET24/full_111_ddr5_soq523_2X_FV.qt|norway|0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15|norway10 
2012/11/14 14:23:19 |a108|Locations 0, 1|NET24/full_111_ddr5_soq523_2X_FV.qt|germany|0,1,2,3|germany10 
2012/11/14 16:23:19 |a108|Locations 0, 1,2,3|NET24/full_111_ddr5_soq523_2X_FV.qt|holland|0,1,2,3|holland10

How we do i get the result out put B.txt

Code

 
2012/11/13 20:06:11 |t112|Locations 12, 13, 14, 15|NET12/full_ddr3_2X_FV_4BD_1.qt|norway|0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15|norway22 
2012/11/14 14:23:19 |t112|Locations 0, 1, 2, 3, 4, 5, 6, 7|NET24/full_111_ddr5_soq523_2X_FV.qt|norway|0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15|norway10 
Currenttime|Available|Locations 8,9,10,11|Available|norway|0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15|norway18  
** norway18 is 10+8 from locations 8 is available, this line not in out put ** 
2012/11/14 14:23:19 |a108|Locations 0, 1|NET24/full_111_ddr5_soq523_2X_FV.qt|germany|0,1,2,3|germany10 
Currenttime|Available|Locations 2,3|Available|germany|0,1,2,3|germany12  
** germany12 is 10+2 from locations 2 is available,  this line not in out put ** 
2012/11/14 16:23:19 |a108|Locations 0, 1,2,3|NET24/full_111_ddr5_soq523_2X_FV.qt|holland|0,1,2,3|holland10

Based on field#6 and compare field#3 with field#5 then write down what location are missing? like norway has location 0,1,2,3,4,5,6,7,12,13,14,15 and missed 8,9,10,11
Can we do that in perl?

Read the first line. Get the field with the country name and create an hash to store the values of field 3 (as keys of the hash) and an array to store the value of the last field.

Get the next line. If the country is the same, add the values of field 3 to the hash. Repeat so long as it is the same country.

When the country changes, iterate on the array values and check whether thay are in the hash. From there you can determina which values are missing.
