=head1	NAME

extract - Text selection and copy from one document to another one

=head1	SYNOPSIS

This sample script extracts every text element matching a given
pattern (string or regex) from a source document and appends it
to a target document. The target document must be an existing one
(empty or not).

The first argument of the command line is the source file name,
the second one is the target file, the third one is the selection
filter (i.e. any quoted string or Perl regular expression)

	unless ($ARGV[0] && $ARGV[1] && $ARGV[2]);

	# document objects initialization
print "Opening $ARGV[0] as source document...\n";
my $source_doc = ooText(file => $ARGV[0])
	or die "$ARGV[0] is not a regular OO file\n";
print "Opening $ARGV[1] as target document...\n";
my $target_doc = ooText(file => $ARGV[1])
	or die "$ARGV[1] is not a regular OO file\n";

	# the imported elements will be appended to the document body
my $root_element = $target_doc->getBody;

	# selection & transfer are done here
print "Selecting the content matching $ARGV[2]...\n";
$target_doc->appendElement($root_element, $_)
	for $source_doc->selectElementsByContent($ARGV[2]);

	# commit the changes in target file
print "Saving the selection in $ARGV[1]...\n";
$target_doc->save;

print "Job complete\n";
