I have question in perl.

I have file whose format is

David|Masters|3      2000      10      500
Harry|Undergrad1|4      4000      23       1000
[download]

I need the first column value (i.e David). The 3rd column has 4 values in it. I need just the first, 3rd value from the third column (e.g 3 and 10). These 3 values I need to match with the first column, second column and the fourth column from the second file. ANd pull out the mismatch rows.

Second file format:

David      |3      |2000      |10      |500      |Masters      |Histor
+y      |English      |
harry      |2      |4000      |12      |0      |Undergrad      |Scienc
+es       |Math            |
harry      |1      |4000      |23      |1000      |Undergrad      |Mat
+h             |History      |

Please advise.

Here there could be spaces in the values of the columns
