[Openxml4j-devs] PackagingURIHelper.relativizeURI

[Nick B. <ope...@ga...>]

Hi All

Just a heads-up that I've ended up largely re-writing this function :/

For .xlsx files, you can have a relation from /xl/worksheets/sheet1.xml to 
/xl/comments1.xml, which excel stores as a relative path of 
../comments1.xml . relativizeURI was incorrectly giving just comments1.xml

Unfortunately, my french wasn't up to understanding the comments in the 
method, to figure out how it was supposed to work, so I ended up replacing 
it with something hopefully quite a bit simpler. All the old tests for 
PackagingURIHelper now pass (including the one that failed before), and 
all the new tests I've added pass too.

But, it's quite a major change, so do shout if you spot any problems with 
it, and I'll endevour to add tests for your uses too! For now though, all 
the relations generated by poi for .xlsx files are being correctly 
relativized, which is quite promising!
