How to use sed modify specific lines

Could anybody tell me how I can use sed to modify lines following specific lines? the file is as following:

"TEST/SI1573.lab"
3670 8920 h#
8920 9530 hh
9530 10694 ih
.
"TEST/DR1/FAKS0/SI2203.lab"
9730 9580 h#
9580 9840 dh
9840 10652 ix
10652 11997 r
........

I want to modify the first fields to 0 of the lines which follows the lines started with "TEST. The file after operation should be:
"TEST/SI1573.lab"
0 8920 h#
8920 9530 hh
9530 10694 ih
.
"TEST/DR1/FAKS0/SI2203.lab"
0 9580 h#
9580 9840 dh
9840 10652 ix
10652 11997 r
........
could anybody tell my how to do that? Thanks in advance.

Apache::TestRun(3)					User Contributed Perl Documentation					Apache::TestRun(3)

NAME
Apache::TestRun - Run the test suite SYNOPSIS
DESCRIPTION
The "Apache::TestRun" package controls the configuration and running of the test suite. METHODS
Several methods are sub-classable, if the default behavior should be changed. "bug_report" The "bug_report()" method is executed when "t/TEST" was executed with the "-bugreport" option, and "make test" (or "t/TEST") fail. Normally this is callback which you can use to tell the user how to deal with the problem, e.g. suggesting to read some document or email some details to someone who can take care of it. By default nothing is executed. The "-bugreport" option is needed so this feature won't become annoying to developers themselves. It's automatically added to the "run_tests" target in Makefile. So if you repeateadly have to test your code, just don't use "make test" but run "t/TEST" directly. Here is an example of a custom "t/TEST" My::TestRun->new->run(@ARGV); package My::TestRun; use base 'Apache::TestRun'; sub bug_report { my $self = shift; print <<EOI; +--------------------------------------------------------+ | Please file a bug report: http://perl.apache.org/bugs/ | +--------------------------------------------------------+ EOI } "pre_configure" The "pre_configure()" method is executed before the configuration for "Apache::Test" is generated. So if you need to adjust the setup before httpd.conf and other files are autogenerated, this is the right place to do so. For example if you don't want to inherit a LoadModule directive for mod_apreq.so but to make sure that the local version is used, you can sub-class "Apache::TestRun" and override this method in t/TEST.PL: package My::TestRun; use base 'Apache::TestRun'; use Apache::TestConfig; __PACKAGE__->new->run(@ARGV); sub pre_configure { my $self = shift; # Don't load an installed mod_apreq Apache::TestConfig::autoconfig_skip_module_add('mod_apreq.c'); $self->SUPER::pre_configure(); } Notice that the extension is .c, and not .so. Don't forget to run the super class' c<pre_configure()> method. "new_test_config" META: to be completed perl v5.16.2 2011-02-07 Apache::TestRun(3)
