parsing xml using awk
hello ,

i am trying to parse xml using awk however its a little bit tricky as i want

Code:
<databases>
                <source>
                        <host>prod</host>
                        <port>1522</port>
                        <tns>GP1</tns>
                        <user>P11</user>
                        <password>lXXXXX</password>
                </source>
                <target>
                        <host>bcp</host>
                        <port>1522</port>
                        <tns>PDG</tns>
                        <user>pg</user>
                        <password>yyyyy</password>
                </target>
        </databases>

Well, the trick is to use either the ">" or the "<" as your record separator.

Code:
 awk -v RS="<" {print} <<+ |\
 awk -F ">" '$1 ~ /^tns$/{TNS=$2}
             $1 ~ /^user$/{USER=$2}
             $1 ~ /^password$/{PW=$2}
             $1 ~ /^\/source$/{print TNS, USER, PW}'
<databases>
                <source>
                        <host>prod</host>
                        <port>1522</port>
                        <tns>GP1</tns>
                        <user>P11</user>
                        <password>lXXXXX</password>
                </source>
+

returns

Code:
GP1 P11 lXXXXX

The rest if formating the output - over to you.

Base on OP data sample:
Code:
awk -F'[<|>]' '/tns/{t=$3}/user/{u=$3}/password/{printf "sqlplus %s/%s@%s\n",t,$3,u}' file

Old 02-17-2009
Code:
nawk 'BEGIN{FS="[<|>]"}
/<tns>/{tns=$3}
/<user>/{user=$3}
/<password>/{printf("sqlplus %s/%s@%s\n",user,$3,tns)}' a.txt

                 printf \                      # I use printf to print the line
                 "sqlplus %s/%s@%s\n",\        # Format the print output
                 t,$3,u                        # Print variable t, value of $3 and variable u
               }
' file                                         # Input file

Next time you should ask the OP Smilie
