[Opensync-devel] xmlformat_compare not working for sub-fields

[Henrik /K. <kaa...@us...>]

xmlformat_compare has a nice way of comparing OSyncXMLFields; adding and 
subtracting "points" to see how well two OSyncXMLFormats match.
However, this does *not* extend to sub-fields.

If we have
  <Name>
    <LastName>Doe</LastName>
    <FirstName>John</FirstName>
  </Name>
and compare to
  <Name>
    <LastName>Doe</LastName>
    <FirstName>John</FirstName>
    <Prefix>Mr.</Prefix>
  </Name>
the two fields will not match, resulting in a -90 points penalty.

Even worse, if we have
  <Name>
    <LastName>Doe</LastName>
    <FirstName>John</FirstName>
  </Name>
and compare this to how file-sync currently reports vcards to xml:
  <Name>
    <LastName>Doe</LastName>
    <FirstName>John</FirstName>
    <Additional></Additional>
    <Prefix></Prefix>
    <Suffix></Suffix>
  </Name>
the two fields will not match either
(we get "Run out of list2 elements. Different.")

Does anyone have a good idea as to how to resolve this issue?
