Support for inline XML DTD

[sebastiannoell]

Hey there! 👋

I have a valid xml with a DTD defined like this:

<!-- demo.xml -->
 <!DOCTYPE example [
  <!ELEMENT example (item)*>
  <!ELEMENT item (name, price)>
  <!ELEMENT name (#PCDATA)>
  <!ELEMENT price (#PCDATA)>
]>
<example>
  <item>
    <name>Item 1</name>
    <price>$10.00</price>
  </item>
  <item>
    <name>Item 2</name>
    <price>$20.00</price>
  </item>
</example>

Versions:

"@prettier/plugin-xml": "^3.2.2",
"prettier": "^3.0.3"

When checking, I am getting this error:

Sadly, wrapping this in an ignore comment block as described in the README.md, the error still persists.

Thanks in advance, Seb :)

Thanks @sebastiannoell! Unfortunately the parser is crashing on this and there's not much we can do about it until the parser supports it. I've upstreamed the request here: SAP/xml-tools#450. I'll close this for now and track it over there.
