Yes, the code need to be corrected.
Using the latest xml attached to your post the following code produces the following result:

Code:
xgawk -lxml 'XMLCHARDATA {
  d[XMLPATH] = $0
  }
XMLENDELEM == "name" {
  XMLPATH == "/domain/server/name" && name = d["/domain/server/name"]
  XMLPATH == "/domain/name"        && domain_name = d["/domain/name"]
  }
XMLENDELEM == "listen-port" && XMLPATH == "/domain/server/listen-port" {
  listen_port = d["/domain/server/listen-port"]
  }
XMLENDELEM == "machine" && XMLPATH == "/domain/server/machine" {
  machine = d["/domain/server/machine"]
  }
XMLENDELEM == "server" {  
  print machine, listen_port, name, domain_name
  }' OFS=: sample.xml

Output:

Code:
:9999:WebLogicAdmin:peoplesoft
Crm-Test-Web:8001:PIA:peoplesoft
Crm-Test-Web:8011:PIA1:peoplesoft
Crm-Test-Web:8021:PIA2:peoplesoft
Crm-Test-Web:8080:RPS:peoplesoft
Crm-Test-Web:8081:PSEMHUB:peoplesoft
Crm-Test-Web:6001:PSOL:peoplesoft

Is it wrong?

Edit: rewritten using the switch statement:

Code:
xgawk -lxml 'XMLCHARDATA { d[XMLPATH] = $0 }
{ 
  switch (XMLENDELEM) {
    case "name": 
      switch (XMLPATH) { 
        case "/domain/server/name":  
          name = d["/domain/server/name"]
          break
        case "/domain/name":
          domain_name = d["/domain/name"]
          break
        }
    case "listen-port":
      XMLPATH == "/domain/server/listen-port" && 
        listen_port = d["/domain/server/listen-port"]
      break
    case "machine": 
      XMLPATH == "/domain/server/machine" && 
        machine = d["/domain/server/machine"]
      break
    case "server":  
      print machine, listen_port, name, domain_name
      break  
    }
  }' OFS=: sample.xml

hwloc-assembler

HWLOC-ASSEMBLER(1)						       hwloc							HWLOC-ASSEMBLER(1)

NAME

       hwloc-assembler - Assemble multiple XML topologies

SYNOPSIS

       hwloc-assembler [options] output.xml [--name <name1>] input1.xml [--name <name2>] input2.xml ...

OPTIONS

       -n --name <name>
	      Set <name> in the AssemblerName info attribute of the next input topology root to ease identification within the final global topol-
	      ogy.

       -f --force
	      Ignore errors while reading input files.

       -v --verbose
	      Verbose messages.

DESCRIPTION

       hwloc-assembler combines the input XML topologies and exports the resulting global topologies to a new XML file.  All inputs are  inserting
       as children of the global root object.  Each input topology root is annotated with info attributes before insertion.  AssemblerIndex is set
       to the index within the list of inputs.	AssemblerName is set to the name given with --name if any.  hwloc-assembler-remote offers a  fron-
       tend for assembling remote nodes topologies without having to manually gather and transfer each of them.

EXAMPLES

       To assemble two nodes topologies:

	   $ hwloc-assembler output.xml --name host1 host1.xml --name host2 host2.xml

RETURN VALUE

       Upon successful execution, hwloc-assembler returns 0.

       hwloc-assembler will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line.
