I am a beginner with gawk. I am having a rough time with this can you help me. I can get certain fields but always end up with the header and all the other data and empty lines.
Sample
11
1234
---------------------------------------------
some.| some |some | some. |some
------------------------------------------------
1| thing1|thing2| thing3|thing4 |
2| thing1|thing2| thing3|thing4 |
3| thing1|thing2| thing3|thing4 |
4| thing1|thing2| thing3|thing4 |

344
5632
---------------------------------------------
OTher.| some |some | some. |some
------------------------------------------------
1| Filed1|Filed2| Filed3|Filed4 |
2| Filed1|Filed2| Filed3|Filed4 |
3| Filed1|Filed2| Filed3|Filed4 |
4| Filed1|Filed2| Filed3|Filed4 |

Would like

thing1 thing3
Filed1 Filed3
but with the option to add other fields etc.
Many Thanks

sure, no problem.

gawk -v things='1:3' things.awk

here's things.awk:

BEGIN {
  n=split(things, thingsA,":");
  for(i=1; i <=n; i++)
     printf("thing%d%s", thingsA[i], (i !=n ) ? OFS : "\n");
    for(j=1; j <=n; j++)
     printf("Field%d%s", thingsA[j], (j !=n ) ? OFS : "\n");
}

Now....... what do you really want to do?

Not very elegant but may do what you want. The hard part
is being able to specify additional fields to print dynamically if that is what you want.

awk -v more=0 '{
                    if ($0 ~ /[0-9]\|/) {
                     split($0,arr,"|")
                     if (more > 0) {
                                 print arr[2],arr[4],arr[more]
                   } else {
                   print arr[2],arr[4]
                   }
}'

OP:
more=0

  thing1     thing3
       thing1     thing3
       thing1     thing3
       thing1     thing3
       Filed1     Filed3
       Filed1     Filed3
       Filed1     Filed3
       Filed1     Filed3

more=1

   thing1     thing3    1
       thing1     thing3    2
       thing1     thing3    3
       thing1     thing3    4
       Filed1     Filed3    1
       Filed1     Filed3    2
       Filed1     Filed3    3
       Filed1     Filed3    4

BEGIN { fields="2 4" ; nf = split(fields,fa)
        FS = " *[|] *" }
6==NF { for (i=1; i<=nf; i++)
          printf "%s%s", $fa[i], (i==nf) ? "\n" : " " }
