How do you create sub-nodes with XML::Smart

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to use XML::Smart to create XML files. Here is my code: my $XML = XML::Smart->new(); $XML->{JOB}{NAME} = $job_name; $XML->{JOB}{DESC} = $desc; $XML->{JOB}{NUM} = $num; Here is the output: <JOB NAME="Name goes here" DESC="Description" NUM="Num goes here"/> I want it to look like this: <JOB NAME="Name goes here"> <DESC>Description</DESC> <NUM>Description</NUM> </JOB> The problem is that I can't create single nodes. The data is all contained in the main node. Any advice would be appreciated. Thanks!

    Well first off, next time please consider using the code tags. It will help the appearance of your post.

    Next, did you check out CPAN? Here I was able to find some sample code.

    Looks like you should use something like

    $XML->{JOB}{DESC}[0] = $desc;
      Duly noted on the code tags. I did try the code you posted but it still have me this output:
      $XML->{JOB}{NAME} = $job_name; $XML->{JOB}{DESC}[0] = $desc; $XML->{JOB}{DATA}[0] = $data; $XML->{JOB}{WHO}[0] = $who; <JOB NAME="Jonname" DESC="Description" DATA="Data..."/>
      I would have thought that it would have given me something like this:
      <JOB NAME="Name"> <DESC>Description</DESC> <DATA>Data</DATA> ...... </JOB>
      ...but it did not. Any other ideas? I have definitely looked over the CPAN site and I didn't see anything that answered my question. Thanks!
        According to the CREATING XML DATAsection, this is the expected behavior.

        So something closer to what you are looking for is this:

        use strict; use XML::Smart; my $job_name = "a job name"; my $desc = "a description"; my $desc2 = "another description"; my $num = "a number"; my $XML = XML::Smart->new(); $XML->{JOB}{NAME}[0] = $job_name; $XML->{JOB}{DESC}[0] = $desc; $XML->{JOB}{DESC}[1] = $desc2; $XML->{JOB}{NUM}[0] = $num; $XML->save('output.xml');
        Which produces:
        <JOB NAME="a job name" NUM="a number"> <DESC>a description</DESC> <DESC>another description</DESC> </JOB>
        So the presence of multiple entries is what makes it a nested element. If this behavior is not what you desire, perhaps XML::Twig or XML::libXML would better work for you. I have got great results from libXML in the past. Update: I checked the tutorial and found what you're looking for.
        $XML->{JOB}{DESC}= $desc; $XML->{JOB}{DESC}->set_node(1) ;
        This code will nest the description as an element. Results:
        <JOB NAME="a job name" NUM="a number"> <DESC>a description</DESC> </JOB>
