Load data from .MAT into .XML

I made some measurements that are stored in .mat files as (e.g. 5x3) matrixes for different N conditions (so, generally 5x3xN-matrixes). How can I load the values from this matrixes into a .XML-pattern (see simplified version below)?

<?xml version="1.0" encoding="UTF-8"?>
 <Data>
  <X>1 2 3</X>
  <Y>100 200 300 400 500</Y>
  <ConditionAxis>25 125</ConditionAxis>
    <Measurements>
     <Condition>
       <Values></Values>
       <Values></Values>
       <Values></Values>
       <Values></Values>
       <Values></Values>
% so that for the 1st condition it would be 5x3-matrix like this:
%       <Values>1 2 3</Values>
%       <Values>4 5 6</Values>         
%       <Values>7 8 9</Values>
%       <Values>10 11 12</Values>
%       <Values>13 14 15</Values>  
     </Condition>
     <Condition>
       <Values></Values>
       <Values></Values>
       <Values></Values>
       <Values></Values>
       <Values></Values>
% and here the other values for the 2nd condition and so on
     </Condition>
    </Measurements>
 </Data>

Thanks before :)

With a single use-case you could just write your own function by expanding the example given in MATLAB help xmlwrite, or you could try out struct2xml or similar from the FileExchange...
