i have to modifiy the awk script in fact using a loop for does not permish to do what i need. 1) I need to change the loop for to a if condition because in the action i will have to add tag name in the script in order to frame tag name from the csv.

for example in the script i will have which is not in the csv to frame which is in the csv to output in xml.

2) User can add tags in the csv with the default tags name before it is generated. for exemple let's consider that tags city and date_liv had been added by user so they took position after the default tags of the csv (column 7 and 8). So how is it possible to add them with a loop starting at column 7 to the end to the xml ?

3) is it possible to rename a tag ? for exemple num_comd by command.

 <rows>
 <C = id_client>
    <client> 
                <identity>              
                            <name>  

                                <M>
                                        <num> </num>
                                        <num_tel> </num_tel>
                                        <num_comd> </num_comd>
                                </M>                                    
                </identity>

            <locomotion>car</locomotion>
</client>
</C>
</rows>

Answer 1

Let's start by writing a script that does what I think I understand you want and then you can tell us what it needs to do differently/additionally:

$ cat tst.awk                             
BEGIN { FS=";"; print "<rows>
" }

NR==1 { for (i=1; i<=NF; i++) f[$i]=i; next }

{ tag = $(f["id_client"]); gsub(/[0-9]/,"",tag) }

tag == "C" { type="client"; flds="num_tel num_comd" }
tag == "D" { type="pro"; flds="id_client num_fixe" }

{
    split("name "flds,n,/ /)
    printf     "<%s: %s>
", tag, $(f["id_client"])
    printf     "    <%s>
", type
    print      "        <identity>"
    for (i=1;i in n;i++)
        printf "            <%s>%s</%s>
", n[i], $(f[n[i]]), n[i]
    print      "        </identity>"
    printf     "        <locomotion>%s</locomotion>
", locomotion
    printf     "    </%s>
", type
    printf     "</%s>

", tag
}

END { print "</rows>" }

.

$ awk -v locomotion='car' -f tst.awk file
<rows>

<C: 50C>
    <client>
        <identity>
            <name>gwenael</name>
            <num_tel>0998452223</num_tel>
            <num_comd>12345</num_comd>
        </identity>
        <locomotion>car</locomotion>
    </client>
</C>

<C: 31C>
    <client>
        <identity>
            <name>marcel</name>
            <num_tel>0966442312</num_tel>
            <num_comd>654321</num_comd>
        </identity>
        <locomotion>car</locomotion>
    </client>
</C>

<D: 23D>
    <pro>
        <identity>
            <name>judith</name>
            <id_client>23D</id_client>
            <num_fixe>1045227937</num_fixe>
        </identity>
        <locomotion>car</locomotion>
    </pro>
</D>

</rows>

Now - what else does it need to do?
