Old 01-05-2015
Just noticed a small error in the regex:
Code:
perl -0777 -pe 'print; print "------\n"; s{<([^/>\s]+)([^>]*)>(?:\s*<([^>]*)\s*>\s*)?</\1\s*>}{<$1$2>$3</$1>}gms;'

The highlighted token is not needed as any whitespace would have been consumed by ([^>]*). Also, the two print statements should not have been included. The corrected code is:
Code:
perl -0777 -pe 's{<([^/>\s]+)([^>]*)>(?:\s*<([^>]*)>\s*)?</\1\s*>}{<$1$2>$3</$1>}gms;'

Apologies for the inconvenience.

NAME
crm_diff - identify changes to the cluster configuration and apply patches to the configuration files SYNOPSIS
crm_diff [-?|-V] [-o filename] [-O string] [-p filename] [-n filename] [-N string] DESCRIPTION
The crm_diff command assists in creating and applying XML patches. This can be useful for visualizing the changes between two versions of the cluster configuration or saving changes so they can be applied at a later time using cibadmin. OPTIONS
--help, -? Print a help message. --original filename, -o filename Specify the original file against which to diff or apply patches. --new filename, -n filename Specify the name of the new file. --original-string string, -O string Specify the original string against which to diff or apply patches. --new-string string, -N string Specify the new string. --patch filename, -p filename Apply a patch to the original XML. Always use with -o. --cib, -c Compare or patch the inputs as a CIB. Always specify the base version with -o and provide either the patch file or the second version with -p or -n, respectively. --stdin, -s Read the inputs from stdin. EXAMPLES
Use crm_diff to determine the differences between various CIB configuration files and to create patches. By means of patches, easily reuse configuration parts without having to use the cibadmin command on every single one of them. 1. Obtain the two different configuration files by running cibadmin on the two cluster setups to compare: cibadmin -Q > cib1.xml cibadmin -Q > cib2.xml 2. Determine whether to diff the entire files against each other or compare just a subset of the configurations. 3. To print the difference between the files to stdout, use the following command: crm_diff -o cib1.xml -n cib2.xml 4. To print the difference between the files to a file and create a patch, use the following command: crm_diff -o cib1.xml -n cib2.xml > patch.xml 5. Apply the patch to the original file: crm_diff -o cib1.xml -p patch.xml FILES
/var/lib/heartbeat/crm/cib.xml--the CIB (minus status section) on disk. Editing this file directly is strongly discouraged. SEE ALSO
