search in array values - powershell

Question

I've an array with 10 values (0 to 9). Each array value output is a multi-liner. Here is what it looks like for example -

C:>arrval[0]
12345
34593433598434
error1
357948557
C:>arrval[1]
238296879234
error1
93454753503
error2

I'm checking to see if we can print only the error portion in an array value.
