Re: twig inbuilt methods to sort whole xml tree

How about this:

$root->first_child->sort_children_on_att("type");
sort_my_kids($root);

$twig->print;
#----------
sub sort_my_kids{
    my $me = shift;
    $me->sort_children_on_value;
    foreach my $kid($me->children){
        sort_my_kids($kid); # Recursive
    }    
}
[download]

Prints:

<enhancement>
  <descriptorgroup>
    <descriptors controlled="y" type="DRG">
      <mainterm weight="a">aspirin</mainterm>
      <mainterm>panadol</mainterm>
      <mainterm>xenon</mainterm>
      <mainterm weight="a">zorro</mainterm>
    </descriptors>
    <descriptors controlled="y" type="MED">
      <descriptor>
        <mainterm>disease</mainterm>
        <mainterm>pestilence</mainterm>
        <mainterm weight="a">plague</mainterm>
      </descriptor>

Hi, I just changed the input as below. __DATA__ <enhancement> <descriptorgroup> <descriptors type="MED" controlled="y"> <descriptor> <mainterm weight="a">plague</mainterm> <mainterm>disease</mainterm> <mainterm>pestilence</mainterm> <link>f</link> <link>C</link> <link>M</link> </descriptor> </descriptors> <descriptors type="DRG" controlled="y"> <mainterm>panadol</mainterm> <mainterm weight="a">zorro</mainterm> <mainterm>xenon</mainterm> <mainterm weight="a">aspirin</mainterm> <link>b</link> <link>P</link> <link>z</link> </descriptors> </descriptorgroup> </enhancement> [download] Most of it is going fine, but one thing I noticed is that it’s moving the position of “mainterm” as well. This won’t work because the xsd/dtd says that <mainterm> must come first, and then the <linkterm>s which are related to it. What is happening at the moment is that it is arrange ALL the tags alphabetically, <mainterm> and <linkterm>. How can this be controlled by the code? <enhancement> <descriptorgroup> <descriptors controlled="y" type="DRG"> <link>P</link> <mainterm weight="a">aspirin</mainterm> <link>b</link> <mainterm>panadol</mainterm> <mainterm>xenon</mainterm> <link>z</link> <mainterm weight="a">zorro</mainterm> </descriptors> <descriptors controlled="y" type="MED"> <descriptor> <link>C</link> <link>M</link> <mainterm>disease</mainterm> <link>f</link> <mainterm>pestilence</mainterm> <mainterm weight="a">plague</mainterm> </descriptor> </descriptors> </descriptorgroup> </enhancement> [download]	[reply] [d/l] [select]
