XML

Actually i want to do few changes in code. i read input sample.xml file.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE labels SYSTEM "label.dtd">
   <labels _FORMAT ="BARCODE" _QUANTITY="1" _PRINTERNAME="P1">

        <label>
             <variable name= "PRTNUM">234243242</variable>
             <variable name= "QUANTY">004342</variable>
             <variable name= "PONUMB">844463541</variable>
             <variable name= "SERIAL">DZ12</variable>
             <variable name= "REV">234235</variable>
             <variable name= "UNITS">234235</variable>
        </label>

     </labels>

& parsed data is placed in parsed.txt

234243242
004342
844463541
DZ12
234235
234235

this data is then merged with barcode.txt

But while merging the data it is merged irrespective of the tag name that is included in xml & barcode file.

e.g
if i put [QUANTY] at the position of [PRTNUM] it will place the same data 234243242 (which actually for [PRTNUM]).
How to make it possible that my program will read the data inside [...] from barcode.txt file & then place the corresponding data from parsed file at that position.

my c code xmldpl.txt
