Using awk for converting xml to txt

Hi,

I have a xml script, I converted it to .txt with values comma seperated using awk function. But I want the output values should be inside double quotes

My xml script (Workorders.xml) is shown like below:

Code:
<?xml version="1.0" encoding="utf-8" ?>
<scbm-extract version="3.3">
<workOrderList>
<workOrder>
<workOrderCode>313194073</workOrderCode>
<branchCode>2021:1206</branchCode>
<demand></demand>
<demandLineItem></demandLineItem>
<priority></priority>
<completionDate>2016-07-10T08:00:00</completionDate>
</workOrder>


-----------------------------------------------------------------------------

I used the below awk command to do this (awk script copied from previous posts)

Code:
awk -f jobxml.awk WorkOrders.xml

jobxml.awk

Code:
BEGIN { FS="[<>]";      OFS=","         }
# Single close-tag
(NF==3) && /^[ \t]*<[/]/        {

        $0=""

        if(!TITLE)      # Print a title line
        {
                for(N=1; N<=L; N++)     $N=T[N]
                print
                TITLE=1
        }

        for(N=1; N<=L; N++)     {       $N=A[T[N]];     delete A[T[N]]  }
        print
}

$2 && $4 && ($2 == substr($4, 2)) {
        if(!T[$2]) { T[$2]=++L; T[L]=$2 }       # Save titles for later
        gsub(/^[ \t]*/, "", $3);                # Get rid of spaces in data
        gsub(/[ \t]*$/, "", $3);
        A[$2]=$3                                # Save for later
}

Output comes like below:

Code:
workOrderCode,branchCode,demand,demandLineItem,priority,completionDate
313194073,2021:1206,,,,2016-07-10T08:00:00

I want to show output like below. ie output values with double quotes

Code:
workOrderCode,branchCode,demand,demandLineItem,priority,completionDate
"313194073","2021:1206","","","","2016-07-10T08:00:00"

Please help me on this

Thanks,
Viswa

Hello Viswanatheee55,

Could you please try following and let me know if this helps you, I have only tested this with your provided Input_file.
Code:
awk 'BEGIN { FS="[<>]";      OFS=",";s1="\""         }
# Single close-tag
(NF==3) && /^[ \t]*<[/]/        {
         $0=""
         if(!TITLE)      # Print a title line
        {
                for(N=1; N<=L; N++)     $N=T[N]
                print
                TITLE=1
        }
         for(N=1; N<=L; N++)     {       $N=s1 A[T[N]] s1;     delete A[T[N]]  }
        print 
         }
 $2 && $4 && ($2 == substr($4, 2)) {
        if(!T[$2]) { T[$2]=++L; T[L]=$2 }       # Save titles for later
        gsub(/^[ \t]*/, "", $3);                # Get rid of spaces in data
        gsub(/[ \t]*$/, "", $3);
        A[$2]=$3                                # Save for later
}'   Input_file

Output will be as follows.
Code:
workOrderCode,branchCode,demand,demandLineItem,priority,completionDate
"313194073","2021:1206","","","","2016-07-10T08:00:00"

Above has been tested with your provided Input_file, if you have more things to do then please mention into your post with complete details.

Try using "," as the field separator
Code:
awk '
  $1=="/" idx {
    if(!Rec) Header=Header "," idx
    Values=Values "\",\"" val
  } 
  {
    idx=$1
    val=$2
  } 
  $1=="/workOrder" {
    if(!Rec++) {
      sub(/,/,x,Header)           # Remove excess field separator
      print Header
    }
    sub(/","/,x,Values)           # Remove excess field separator
    print "\"" Values "\""        # Print adding extra quotes around the Values string
    Values=""
  }
' RS=\< FS=\> file

Output:
Code:
workOrderCode,branchCode,demand,demandLineItem,priority,completionDate
"313194073","2021:1206","","","","2016-07-10T08:00:00"

Hi,

When I use the above code it shows like below

Code:
awk -f jobxml.awk WorkOrders.xml

Code:
awk: jobxml.awk:1: awk 'BEGIN { FS="[<>]";      OFS=",";s1="\""         }
awk: jobxml.awk:1:     ^ invalid char ''' in expression

Thanks,
Viswa

Hello Viswa,

Solution posted in POST#2 by me worked for me. Could you please try following and let me know if this helps you.
Code:
awk -vs1="\"" 'BEGIN { FS="[<>]";      OFS=",";}
# Single close-tag
(NF==3) && /^[ \t]*<[/]/        {
         $0=""
         if(!TITLE)      # Print a title line
        {
                for(N=1; N<=L; N++)     $N=T[N]
                print
                TITLE=1
        }
         for(N=1; N<=L; N++)     {       $N=s1 A[T[N]] s1;     delete A[T[N]]  }
        print 
}
 $2 && $4 && ($2 == substr($4, 2)) {
        if(!T[$2]) { T[$2]=++L; T[L]=$2 }       # Save titles for later
        gsub(/^[ \t]*/, "", $3);                # Get rid of spaces in data
        gsub(/[ \t]*$/, "", $3);
        A[$2]=$3                                # Save for later

I got it Ravinder. Thank you so much for your help

Thanks,
Viswa

---------- Post updated at 06:04 AM ---------- Previous update was at 03:49 AM ----------

Hi Ravinder,

One more requirement

I dont want to list whole xml tags, Just need to list few xml tags.

I want to list the rows only for "workOrderCode,branchCode,demand,completionDate" columns

That means output should be like

Code:
workOrderCode,branchCode,demand,completionDate
"313194073","2021:1206","","2016-07-10T08:00:00"

Thanks,
Viswa
