Exclude the header row in the file to validate
Hi All,

File contains header row.. we need to exclude the header row...no need to validate the first row in the file.
Data in the file should take valid data(two columns)..we need to exclude the more than two columns in the file except the first line.
Code:
email|firstname
a|123|100
b|345
c|456|123|123
d|456
e    456

i need output for the file..
Code:
 email|firstname
b|345
d|456

Thanks,
