I think I was misunderstood.
I think you thought I was asking : "I need to add each property like
bold\italic\underline separatly to the RedlineParams".
What I actually meant to ask was:
Currently there are a lot of XML nodes that might appear under 'rPr' node
(that is under the 'rPrChange').
For example: 'bold', 'boldbidi', 'italic', 'italicbidi', language, etc.
Currently each of these XML nodes is handled by different code in the
'DomainMapper.cxx' file
(here is some of it:
http://opengrok.libreoffice.org/xref/core/writerfilter/source/dmapper/DomainMapper.cxx#2100
)

So I am asking - do I have to go node-by-node and add it to the
'property-list' that will be in the 'RedlineParams'?
Or is there any smart way of turning on some flag when the 'rPrChange->rPr'
tag is entered,
and checking at the end of the 'rPrChange->rPr' tag which properties were
inserted to the 'rContext' and add those properties to the 'RedlineParams'.

Best,
Adam
