How to ignore Pipe in Pipe delimited file?

Hi guys,

I need to know how i can ignore Pipe '|' if Pipe is coming as a column in Pipe delimited file

for eg:
file 1:
using below awk command

awk 'BEGIN {FS=OFS="|" } print $3

i would get xyz

But i want as :

xyz|zzz to consider as whole column representing as 3rd coulmn in that file

Hi ths would give me searching "" and printing but i dont want to avoid Pipe delimited as well my file is totally having columns with pipe dilimted so i want to cosider if "xyz|zzz" occurs it should take as single col

xx|yy|"xyz|zzz"|12 ...

$1 - xx
$2 - yy
$3 - xyz|zzz
$4 - 12

You could try something like:
sed 's#\("[^|]*\)\([|]\)\([^|]*"\)#\1,\3#g' file | awk -F\| '{gsub(/"/,x);sub(",","|",$3);print $3}'

The sed is substituting the pipe to comma so that awk can recognize it as one field.

Later awk substitute the comma back to pipe.

Found this ugly code using google so can not help you with it, only that its replace the | , to make it work
Some guru may be able to simplify it Smilie

sed -e 's/|/,/g' file | awk '{
while($0) {
  match($0,/[^,]*,| *"[^"]*" *,/);
  gsub(/^ *"?|"? *,$/,"",f);
  print "Field " ++c " is " f;
Field 1 is xx
Field 2 is yy
Field 3 is xyz,zzz
Field 4 is zzz
Field 5 is 12.

PS you may find some here:

Maybe you can adapt this post to fit your needs? It's for commas in comma delimited fields, but it should do the task after some fiddling...

Thanks Yoda i will try to apply this but wat i needed is
i am having a file with | seperated in which i need to search char in 3rd column and replace with null. i need to replace only the coulmn where character occurs in 3rd field
for eg:


output file:

the above one i achieved with this below code using
awk 'BEGIN {FS=OFS="|" } $3 ~ /[[:alnum:]]/ { $3="" }1' file

but wat i faced is if there is any column having pipe that should consider as single column

not i should achieve my requirement like this

now AAA should replace with null considering as AAA as 4th column if use
awk 'BEGIN {FS=OFS="|" } $4 ~ /[[:alnum:]]/ { $4="" }1' file
