Question

I am not seeing what I am doing wrong. To see what was being done, I changed the constructor values to “TEST”, after the XML gets read in (I verified what the XML is), the class values are still stuck to “TEST”. Any more Ideas? I am doing this process already in another class that works fine, neither me nor some co-workers could find the difference.

XML:

<IntervalTranslatorScrubberSetting>
  <LINEINDICATOR_USAGE>USG</LINEINDICATOR_USAGE>
  <FILETYPE>867</FILETYPE>
  <ESIDUNS>8417397824</ESIDUNS>
</IntervalTranslatorScrubberSetting>

CLASS: (Tried without the XMLElement, and tried using XMLAttribute just to see, no change)

Answer 1

Okay using @maxc ‘s suggestion, I tried the serialization of the class, and saw nothing different except for the capitalization of my XML attributes vs. my properties. I did not think this stuff was case sensitive? But when I changed it so their cases matched, it works, even changed it back and forth to confirm.

Weird?
