Question

I am using the svn log --xml response to look at the changes for a particular revision. But in case of an invalid revision or path, I want to just to get a blank but valid xml response. Is it possible to do that?

So instead of this:

<?xml version="1.0"?>
<log>
svn: Unable to find repository location for 'http://subversion.ny.jpmorgan.com /svn/repos/IM_RPS_CORE/rps_deploy_tools_content_test/branches/rol-201106-content-test' in revision 1556

I could get:

<?xml version="1.0"?>
<log>
</log>

Thanks!

No can do.

However, if you check the exit status code of your svn log command, you can handle the issue yourself. For example, in a Bash shell script:

if ! svn log --xml $url > $xmlOutput 2> /dev/null
then
     cat > $xmlOutput <<EOF
<?xml version="1.0"?>
<log>
</log>
EOF
