I need help getting over this bump on how nested for loops work in shell. Say i was comparing files in a directory in any other language my for loop would look like so for(int i=0;to then end; i++) for(int y = i+1; to the end; y++) I can't seem to understand how i can translate that...

xmldiff

XMLDIFF(1)							   User's Manual							XMLDIFF(1)

NAME

       xmldiff - Tree 2 tree correction between xml documents

SYNOPSIS

       xmldiff [ options ] original_file modified_file

       xmldiff [ options ] -r original_directoty modified_directory

DESCRIPTION

       xmldiff	is  a  utility for extracting differences between two xml files.  It returns a set of primitives to apply on source tree to obtain
       the destination tree.

       The implementation is based on Change detection in hierarchically structured information, by S. Chawathe, A.  Rajaraman,  H.  Garcia-Molina
       and J. Widom, Stanford University, 1996

OPTIONS

       -h, --help
		   display this help message and exit.

       -V, --version
		   display version number and exit

       -H, --html
		   input files are HTML instead of XML

       -r, --recursive
		   when comparing directories, recursively compare any
		   subdirectories found.

       -x, --xupdate
		   display output following the Xupdate xml specification
		   (see http://www.xmldb.org/xupdate/xupdate-wd.html#N19b1de).

       -e <encoding>, --encoding=<encoding>
		   specify the encoding to use for output. Default is UTF-8

       -n, --not-normalize-spaces
		   do not normalize spaces and new lines in text and comment nodes.

       -c, --exclude-comments
		   do not process comment nodes

       -g, --ext-ges
		   include all external general (text) entities.

       -p, --ext-pes
		   include all external parameter entities, including the external DTD
		   subset.

       --profile=<file>
		   display an execution profile (run slower with this option),
		   profile saved to file (binarie form).

EXIT STATUS

	 0 means no difference were found.

	 A positive number means some differences were found.

	 A negative number means an error occured.

KNOWN PROBLEMS

       xmldiff	uses  an  algorithm  with a (too) high algorithmical complexity, which makes it unsuitable to process large XML documents. If your
       document has more than about 100 nodes, you should probably look for an alternative solution.

       Any suggestion to this issue is welcome by Logilab. Please tell us if you are aware of a simpler algorithm to solve this problem.

REQUIRES

       python, pyxml
