Looks like the problem is in the design and not the tool. Question: are lists, entries, and titles types of tags, or are they something else? If you want them to be tags, then make them common tags that can have different attributes: 
<?xml version="1.0" encoding="UTF-8"?>
<tags>
<tag type="title" params="blah">Zero</tag>
<tag type="list" params="123">First</tag>
<tag type="entry" params="456">Second</tag>
<tag type="flag" params="123">Third</tag>
</tags>

When run through the same code, this output is generated: 
$VAR1 = {
  'tags' => [
    {
      'tag' => [
        {
          'params' => 'blah',
          'content' => 'Zero',
          'type' => 'title'
        },
        {
          'params' => '123',
          'content' => 'First',
          'type' => 'list'
        },
        {
          'params' => '456',
          'content' => 'Second',
          'type' => 'entry'
        },
        {
          'params' => '123',
          'content' => 'Third',
          'type' => 'flag'
        }
      ]
    }
  ]
};

There are advantages to both approaches. This approach allows you to preserve the order of your 'tags', but the other approach allows you to drill-down to a specific list of tags in O(1).

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
