Danis³h Short-Form Notation of XML and HTML

In addition to the standard Danis³h Notation of HTML and XML, Danis³h has a more concise short-form notation.

The short-form notation is not identical to, but inspired by the output produced by the combination of two functions native to PHP:

simplexml_load_string()
json_encode()

e.g.

$My_XML_String = '<note><to>Alice</to><from>Bob</from><heading>Question</heading><body>Have you seen my chocolate pretzels?</body></note>';
$My_XML_Object = simplexml_load_string($My_XML_String);
$My_XML_JSON = json_encode($My_XML_Object);

The differences between the output of the PHP script immediately above and Short-Form Danis³h Notation are minor but important:

Example XML

<note>
<to>Alice</to>
<from>Bob</from>
<heading>Question</heading>
<body>Have you seen my chocolate pretzels?</body>
</note>

PHP Native Functions Output:

{"to":"Alice","from":"Bob","heading":"Question","body":"Have you seen my chocolate pretzels?"}

Danis³h Short-Form Notation

{"note":{"to":{"txt":"Alice"},"from":{"txt":"Bob"},"heading":{"txt":"Question"},"body":{"txt":"Have you seen my chocolate pretzels?"}}}

Example HTML

<section><div><p>This is a test.</p><p>This is another test.</p><nav></nav></div><div><p>This is a third test.</p><p>This is a fourth test.</p><hr/><span>Something else.</span><hr/><p>This is a fifth test.</p></div></section>

Example Input (Long-form HTML Notation in Danis³h)

[{"element":"section","elementChildren":[{"element":"div","elementChildren":[{"element":"p","elementChildren":[{"plainText":"This is a test."}]},{"element":"p","elementChildren":[{"plainText":"This is another test."}]},{"element":"nav","elementChildren":[]}]},{"element":"div","elementChildren":[{"element":"p","elementChildren":[{"plainText":"This is a third test."}]},{"element":"p","elementChildren":[{"plainText":"This is a fourth test."}]},{"element":"hr","self-closing":true},{"element":"span","elementChildren":[{"plainText":"Something else."}]},{"element":"hr","self-closing":true},{"element":"p","elementChildren":[{"plainText":"This is a fifth test."}]}]}]}]

Example Output (Short-form HTML Notation in Danis³h)
