Processing of comments in XML is buggy

[Kopfbremse]

Version of yq: 4.30.2
Operating system: linux
Installed via: binary release

Bug description
Comments in XML are parsed with type == "!!null".
Order of comments and nodes are not stable.

Input

<root>
  <!-- comment 1 -->
</root>

---

Undefined type for comments

yq --input-format xml '.. | type' input.xml

Output

!!map
!!null

---

The order of comment and root node are swapped

yq --input-format xml '.' input.xml

Output

# comment 1
root:

---

It is not possible to select the comments for further processing

yq --input-format xml '.. | select(type == "!!null")' input.xml

The command produces no output.

---

The comment is selected together with the map

yq --input-format xml '.. | select(type == "!!map")' input.xml

Output

# comment 1
root:

Yeah it's been real hard to put the comments in the right place, I'd be surprised if there weren't more issues.
Will fix in next release

For the record, comments placed above the map key like that are on the map key node, not the value. You'll need to use triple dots ... or the key operator to select them

Fixed in 4.30.5
