I want to use TortoiseSVN as the poor man's CMS for my XML project (based on DITA DTDs). The built-in diff-merge is line oriented, as are many other diff tools intended for programmers. This can lead to excessive flagging of differences in XML files which, by XML conventions for white space, linebreaks, attribute order, etc. are perfectly identical. Has anybody successfully used <oXygen/> as an XML diff-merge tool with TortoiseSVN or any other programming version management programme? How do you set TortoiseSVN up to invoke <oXygen/> and pass filename parameters, etc.? Any help received will earn my undying and pathetic gratitude! Regards, Hedley P.S.
