问题
There seems to be many questions WRT tool to generate diffs between xmls, but there wasn't this question yet, so anyone who knows this show me a link or paste any example anyone already solved this problem.
Canonicalizing an xml file means,
- reordering the appearance of attributes
- reordering the appearance of tags (selectable by command line option)
- insert line ending(CR/CR+LF/LF) if there isn't at the end of a close tag
- insert indentation tab(space)
- remove redundant spaces and line endings
And then you can cleanly diff the xml files to see which part was updated.
I want to use the routine to canonicalize in unix environment, as quick as possible, before checking in to version control repository.
回答1:
XMLStarlet has a canonicalization mode (c14n).
回答2:
