How to find the text at specified character position (CP)

[Viliam Ďurina <vi...@kios.sk>]

Hello,

I'm trying to parse bookmarks and cross-references from word documents. I have parsed the sttbBkmk and plcbkf tables, from which I get the starting character position, where the bookmark points at. But I fail to find the text at that position. Is there a way for a particular CharacterRun to tell, which character position it starts at?

Thanks, Viliam

Some further links if you want some examples: I have some similar things
in the ww8dumper.

You might want to double check the word specs, and ensure you're handling 
the offsets in the correct one of bytes or characters. It's quite messy 
which one is used where, and you'll want to ensure you're correctly in the 
character domain before finding text

Yup, if you look at:
http://poi.apache.org/apidocs/org/apache/poi/hwpf/usermodel/CharacterRun.html
then follow it back to the parent Range object:
http://poi.apache.org/apidocs/org/apache/poi/hwpf/usermodel/Range.html
you have things like getStartOffset(), getEndOffset(), and the details on 
where the section and paragraphs start
