Help:mod_rewrite: /directory/ --> /page.php?id=directory does not work

RewriteRule of directory

[iProgram]

I have successfully used .htaccess file to rewrite www.mysite.com/info-123.html to www.mysite.com/showinfo.php?id=123

Now I want to rewrite directory, for example:
www.mysite.com/sth/aaa/xyz-info-123.html to www.mysite.com/showinfo.php?dir=aaa&name=xyz&id=123

I use the following rewrite rule to make a test:

RewriteRule ^/NetTools$ /test.php?target=3
RewriteRule ^/NetTools/Messengers$ /test.php?target=34

or
RewriteRule /directory/([0-9]+) /dbase.php?id=$1

But it does not work at all :(

Maybe there's an error on a previous line?

iProgram,

In an .htaccess context, do not use a preceding slash on your patterns. Also, do not use an end anchor ($) unless you wish to rewrite only requests which have no trailing slash or further path info appended.

RewriteRule ^NetTools /test.php?target=3 [L]
RewriteRule ^NetTools/Messengers /test.php?target=34 [L]
or
RewriteRule directory/([0-9]+) /dbase.php?id=$1 [L]
