Filename: 0.10.4/FWObjectDatabase.xslt
Author: Vadim Kurland
Build date: 01/17/2002
Last changed: 03/01/2002
Version: 1.0.0
Description: translates fwbuilder object database from v0.10.4 to v0.10.5
adds group "Address Ranges" (ID='stdid14')
adds subelement Management to Host and Firewall and moves
attributes snmp_read_community and snmp_write_community to
Management/SNMPManagement
moves attributes inst_script and inst_cmdline to the element
PolicyInstallScript
fixes Interface elements that have address element but it
is an empty string
adds missing TCP flags 'PSH' and 'URG' to all TCPService
elements
changes platform name 'ipfilter' -> 'ipf'
****************************************************************************
* *
* Files of versions 0.10.3 and older did not have namespace. Files *
* starting from v 0.10.4 have namespace defined in the element *
* FWObjectDatabase as follows: *
* *
* <FWObjectDatabase xmlns="http://www.fwbuilder.org/1.0/" *
* version="0.10.4" id="root"> *
* *
* I've replaced transformation for upgrade 0.10.3->0.10.4 so the new one *
* now adds namespace in the same way. People who upgrade from older *
* versions will use this new transormation and will get intermediate *
* data tree (of version 0.10.4) with namespace defined in it. *
* *
* Therefore I could build transformation for upgrade 0.10.4->0.10.5 *
* assuming that the namespace declaration is always there. *
* *
* Transformation 0.10.3->0.10.4 does not add namespace prefixes to the *
* elements. It only adds namespace declaration using xmlns in the root *
* element. *
* *
* This transformation (0.10.4->0.10.5) uses its own loacally defined *
* prefix 'fwb' to be able to match on elements with the namespace. This *
* prefix is defined in xsl:stylesheet element. This prefix won't be *
* added to the output data, it is used only within this transformation. *
* *
