Hi, I am fairly new to Perl and got a task where I need some help. I want to parse a xml file which has its own xml structure into an array and manipulate the data in the xml. Depending on other child information within the xml file I want to create another parent/child in it. I tried the package XML::SIMPLE and I can read out an XML but when I try to read my data by just selection the info I need it wont return a value. This is my dtd: (snipe) 
<!ELEMENT DEFJOB (JOB+)>

<!ELEMENT JOB (TAG_NAMES*,(TAG_NAMES | INCOND | OUTCOND | AUTOEDIT | Q
+UANTITATIVE | CONTROL | SHOUT | STEP_RANGE | ON)*)>

<!ELEMENT OUTCOND EMPTY>

Below is a xml example: Within the data-set I find the GROUP / NODEID from witch I need to create the new child "QUANTITATIVE NAME". 
<?xml version='1.0' encoding='ISO-8859-1' ?>
<!DOCTYPE DEFJOB SYSTEM "/aa/em/ddd/e62xstf3/resource/defjob.dtd">
 <DEFJOB >
  <JOB
   GROUP="xp_maint"
   NODEID="localhost"
   USE_INSTREAM_JCL="0"
>
   <QUANTITATIVE NAME="QR1-INIT" QUANT="1" />
   <QUANTITATIVE NAME="QR2-NODEID" QUANT="1" />
   <QUANTITATIVE NAME="QR3-GROUP" QUANT="1" />
/>
   </ON>
  </JOB>

My Question: 1. What would be the best package to use? XML::SIMPLE? I was thinking to read the data into an array, then to see if any "QUANTITATIVE NAME" is used, if not I would create new ones with the GROUP / NODEID. Thanks in advanced for any help
