Hi all,

Thanks for continuous help but this time my output file is completely blank!

I am attaching here my sample input file.

Kindly check it.
sample.txt (6.2 KB)

The first line in your file is a killer - it does not obey any rules. You might want to deal with it separtely. Try this - works on linux/mawk:
Code:
awk     '{gsub(/\n/,"") 
          Ar[++i]=$1}   
          /Phase/ {for (j in Ar)  print Ar[j], $NF; delete Ar; i=0}
        ' RS="\|?[A-Za-z ]*: " FS="   *" OFS="\t" file

What it does is split the file at "Drugs: ", "other: " etc, register all first fields until a phase information shows up, and then print all registered first fields together with the respective phase info.
The exotic record and field separators will not work on all awk implementations.

With your new sample file, use FS="\t" in lieu of FS=" *"

There are few lines where phase is not present.

So i added previous phase of the line.

Code:
sed "s/^Drug: //;s/Drug: /|/g;s/ *||* */|/g;s/ *Phase/@Phase/" file | awk -F"@" '{if($2){s=$2};n=split($1,d,"|");for(j=1;j<=n;j++) {print d[j]":"p[i],s}}'

If you want to keep as it is blank. then use below.

Code:
sed "s/^Drug: //;s/Drug: /|/g;s/ *||* */|/g;s/ *Phase/@Phase/" file | awk -F"@" '{n=split($1,d,"|");for(j=1;j<=n;j++) {print d[j]":"p[i],$2}}'

Have you tried my code?

In my previous post I already mentioned that. There are few line which don't have phase in your input file. Please look at my previous post.

Hello Pamu,

Yes I checked. Thanks for your help.

But my expected out put is like this if a sentence is mentioned like this:

Drug: MK-3102|Drug: Matching placebo to MK-3102|Drug: Basal medication Phase 3

expected output is

Code:
Code:
MK-3102                                               Phase 3
Matching placebo to MK-3102            Phase 3
Basal medication                                   Phase
3

For lastline expected output is

Drug: Alogliptin and glimepiride|Drug: Alogliptin and glimepiride|Drug: Alogliptin and metformin|Drug: Alogliptin and metformin Phase 2|Phase 3



Code:
Alogliptin and glimepiride         Phase 2|Phase  3
Alogliptin and glimepiride          Phase 2|Phase  3
Alogliptin and metformin           Phase 2|Phase  3
Alogliptin and metformin           Phase 2|Phase  3

so anyhting between Drug: and the symbol | get separated with phase mentioned in front of line in second column.

Although I dont want duplicates as present in second line but if it is there I can manage. But good nto to have duplicates

Code:
Code:
Alogliptin and glimepiride         Phase 2|Phase  3
Alogliptin and metformin           Phase 2|Phase  3

But I can use another programm fo rthat lateron but separation is a bit difficult
[/CODE]

if there is not phase all the words in front of it will be blank
for eg drug: MK01 drug:VV09

Code:
  MK01
   VV09

so in front of these two words there are blank spaces without any phase. Thats what I expected.
