Finding the modules where changes were checked wit

Question

I have a multi module maven project.

Project
    -Module1
    -Module2
    -Module3
    -Module4
    -Module5

I want to find the modules to which files were checked in based on the revision number.

I know svn log -v -r12345 -r12346 svn://repo-path.com/project will get the log for the changed paths but I want only the module names.

For eg: from the following log I want

I want PROJECT.SHARED , PROJECT.SRE and MODULE.CYCLE to be picked up maybe in a log file to use them later for a build process.

How can I do this when I want to manually pass multiple revision numbers and generate the list of modules where changes were checked into via svn.

Three separate tasks:

1. call svn properly to create the log
2. parse the log
3. Write the parsed values somewhere

1.

import subprocess as sp

svn_url = "svn://repo-path.com/project"
revisions = [12345, 12346]
revision_clargs = ["-r%i" % revision for revision in revisions]
popen = sp.Popen(["svn", "log", "-v"] + revision_clargs + [svn_url],stdout=sp.PIPE,stderr=sp.PIPE)
out,err = popen.communicate()

2.

input_ = """

3. Depends on what you want...
