generate xml from structured text file in java

i have several text files containing text in this format

DEF LOCA_MISSL T6.2
LOCA_MISSL = 0
SI HJOU_DATE <= TEMP_DATJOU
   SI HJOU_INMISS <> "0"
      PLAGE "DJ"
      SI TEMP_TYPPLA <> " "
         LOCA_DEJDEB = TEMP_VALTRT1
         LOCA_DEJFIN = TEMP_VALTRT2
      FINSI
   FINSI
FINSI

i want to generate an xml file from the text using java. is there any framework (SAX ??) that can help me do this, i already started coding this without any framework but it's too complicated especially when it come to using XML References.
