For docx4j users who wants to analyze and edit the XML parts of a docx/pptx/xlsx, the attached swing
program DocWin.java will be helpful. (I got sick of the tedium of manually unzipping, opening different
parts in a editor, zipping it back up if needed, etc.) DocWin shows the package's parts on the left, in
a tree reflecting the relationship hierarchy, and on the right shows the contents of the part selected on
the left. XML is formatted and indented for readability. The XML is editable, and you can save the
whole thing back out if you want. There's no validation of your XML though, at least not yet.
Jason, this is in the org.docx4j.samples package, you can add it to SVN if you think it's appropriate.
