So yeah XML is still not solved in year 2018. Or so did I realize the last days.
I use jackson to serialize generic data to JSON.

Now I also want to provide serialization to XML. Easy right? Jackson also provides XML serialization facitlity similar to JAXB.

Works out of the box (more or less). Wait what? *rubbing eyes*

<User>
<pk>234235</pk>
<groups typeCode="usergroup">
<pk>6356679041773291286</pk>
</groups>
<groups typeCode="usergroup">
<pk>1095682275514732543</pk>
</groups>
</User>

Why is my groups property (java.util.Set) rendered as two separate elements? Who the fuck every though this is the way to go?

So OK *reading the docs* there is a way to create a collection wrapper. That must be it, I thought ...

<User typeCode="user">
<pk>2540591810712846915</pk>
<groups>
<groups typeCode="usergroup">
<pk>6356679041773291286</pk>
</groups>
<groups typeCode="usergroup">
<pk>1095682275514732543</pk>
</groups>
</groups>
</User>

What the fuck is this now? This is still not right!!!

I know XML offers a lot of flexibility on how to represent your data. But this is just wrong ...

The only logical way to display that data is:
<User typeCode="user">
<pk>2540591810712846915</pk>
<groups>
<groupsEntry typeCode="usergroup">
<pk>6356679041773291286</pk>
</groupsEntry>
<groupsEntry typeCode="usergroup">
<pk>1095682275514732543</pk>
</groupsEntry>
</groups>
</User>

It would be better if the individual entries would be just called "group" but I guess implementing such a logic would be pretty hard (finding a singular of an arbitrary word?).

So yeah theres a way for that * implementing a custom collection serializer* ... wait is that really the way to go? I mean common, am I the only one who just whants this fucking shit just work as expected, with the least amount of suprise?
Why do I have to customize that ...

So ok it renders fine now ... *writes test for it+
FUCK FUCK FUCK. why can't jackson not deserialize it properly anymore? The two groups are just not being picked up anymore ...

SO WHY, WHY WHY are you guys over at jackson, JAXB and the like not able to implement that in the right manner. AND NOT THERE IS ONLY ONE RIGHT WAY TO DO IT!

*looks at an apple PLIST file* *scratches head* OK, gues I'll stick to the jackson defaults, at least it's not as broken as the fucking apple XML:

<plist version="1.0">
<dict>
<key>PayloadOrganization</key>
<string>Example Inc.</string>
<key>PayloadDisplayName</key>
<string>Profile Service</string>
<key>PayloadVersion</key>
<integer>1</integer>
</dict>
</plist

I really wonder who at apple has this briliant idea ...
