I have this xml assigned to a variable called "$data": 
<employees>
 <employee>
    <empid>9</empid>
    <fname>Joe</fname>
    <lname>A</lname>
  </employee>
  <employee>
    <empid>3</empid>
    <fname>Larry</fname>
    <lname>W</lname>
  </employee>
  <employee>
    <empid>7</empid>
    <fname>Perl</fname>
    <lname>L</lname>
  </employee>
</employees>

I have this perl script which uses XML::Simple to parse the xml file: 
$parsed = eval {XMLin($data)};

if ($@) {
  print $@;
} else {
    <NEED SORTING CODE HERE>
}

So, what i need is to be able to sort the XML using the <empid> tag...so the xml should be sorted like this: 
<employees>
  <employee>
    <empid>3</empid>
    <fname>Larry</fname>
    <lname>W</lname>
  </employee>
  <employee>
    <empid>7</empid>
    <fname>Perl</fname>
    <lname>6</lname>
  </employee>
  <employee>
    <empid>9</empid>
    <fname>Joe</fname>
    <lname>A</lname>
  </employee> 
</employees>
