Why can't you take a "log" of that element? That'll give you all the
revisions on which that element changed. You can do a "--stop-on-copy" to
prevent from going further back in time. You can even use the "--xml" flag
and parse the output that way. This will give you a list of all the
revisions where the file was changed. The truth is that even if the element
didn't change, it is still a valid revision. For example, if the first
revision is 193, and the last revision is 14,320, I can easily assume that
revision 193 through 14,320 are valid revisions for that element.
By the way, "svn log" can work both ways: From first to last or from last to
first. It all depends how you list the releases:
$ svn log 1:HEAD $element #List from first to last
$ svn log HEAD:1 $element #List from last to first.
BTW, notice that the element doesn't need a revision 1 for the above
commands to work. It'll merely list the first revision of that element.
