Mapping: Sorting nodes

Question

Hello all,
please see below input document which should be converted to output below in PI.
Nodes //node1/item should be sorted in same order like //node2/item (identified by value of <pid>) and if item does not exist in node2 (like with pid=501 below) it should get a position at the end. //node2 should be copied 1:1.
Any ideas for this mapping in XSLT, Java Mapping or with Graphical Mapping and UDF?
Regards
Markus
Input:
<root>
  <node1>
     <item>
       <pid>201</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
     <item>
       <pid>401</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
     <item>
       <pid>501</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
     <item>
       <pid>101</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
  <node1>
  <node2>
    <item>
       <pid>101</pid>
    </item>
    <item>
       <pid>401</pid>
    </item>
    <item>
       <pid>201</pid>
    </item>
  <node2>
</root>
Output:
<root>
  <node1>
     <item>
       <pid>101</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
     <item>
       <pid>401</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
     <item>
       <pid>201</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
     <item>
       <pid>501</pid>
       <name>MA</name>
       <street>
          <no>123</no>
       </street>
     </item>
  <node1>
  <node2>
    <item>
       <pid>101</pid>
    </item>
    <item>
       <pid>401</pid>
    </item>
    <item>
       <pid>201</pid>
    </item>
  <node2>
</root>

Hi Markus,
This is only achievable by using UDF. Please refer to mapping below:
for node1:
pid(node1) --> mapWithDefault:suppressed --> concat: : --> concat: : --> removeContext --> UDF1 --> node1
name --> mapWithDefault:suppressed ----------> /            /                                /
no --> mapWithDefault:suppressed ------------------------> /                                /
pid(node2) --> removeContext ------------------------------------------------------------> /
UDF1 is of CONTEXT Type, the arguments are:
Arr1
Arr2
Here is the code:
GlobalContainer globalContainer = container.getGlobalContainer();
String sortedArr[] = new String[Arr1.length];
String out = "";
int cnt = 0;
for(int a=0;a<Arr2.length;a++){
   for(int b=0;b<Arr1.length;b++){
      if(Arr1<b>.indexOf(Arr2[a])>-1){
        sortedArr[cnt]=Arr1<b>;
        Arr1<b> = "retrieved";
        cnt++;
for(int a=0;a<Arr1.length;a++){
   if(!Arr1[a].equals("retrieved")){
      sortedArr[cnt]=Arr1[a];
      cnt++;
for(int a=0;a<sortedArr.length;a++){
   out += sortedArr[a] + " ";
   result.addValue(sortedArr[a]);
globalContainer.setParameter("Result",out);
for pid:
Constant:PID --> mapWithDefault --> UDF2 --> SplitByValue:eachValue --> pid
for name:
Constant:NAME --> mapWithDefault --> UDF2 --> SplitByValue:eachValue --> name
for no:
Constant:NUMBER --> mapWithDefault --> UDF2 --> SplitByValue:eachValue --> no
UDF2 is of CONTEXT TYPE, input argument is: param
Here is the code for UDF2:
GlobalContainer globalContainer = container.getGlobalContainer();
String temp  = (String) globalContainer.getParameter("Result");
String arr[] = temp.split(" ");
if(param[0].equals("PID")){
   for(int a=0;a<arr.length;a++){
      result.addValue(arr[a].substring(0,arr[a].indexOf(":")));
else if(param[0].equals("NAME")){
   for(int a=0;a<arr.length;a++){
      result.addValue(arr[a].substring(arr[a].indexOf(":"),arr[a].lastIndexOf(":")));
else
   for(int a=0;a<arr.length;a++){
     result.addValue(arr[a].substring(arr[a].lastIndexOf(":"),arr[a].length()));
Hope this helps,
Mark
