// This is not a generic registry reader. We assume the following structure:
|
|
// Last element of Key becomes prop, first part is the path and optionally nodes,
|
|
// when the node has oor:op attribute.
|
|
// Values can be the following: Value (string), Type (string, optional),
|
|
// Final (dword, optional), External (dword, optional), ExternalBackend (string, optional),
|
|
// Nil (dword, optional)
|
|
//
|
|
// For example the following registry setting:
|
|
// [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
|
|
// "Value"="Example Corp."
|
|
// "Final"=dword:00000001
|
|
// becomes the following in configuration:
|
|
// <!-- set the Company name -->
|
|
// <item oor:path="/org.openoffice.UserProfile/Data">
|
|
// <prop oor:name="o" oor:finalized="true">
|
|
// <value>Example Corp.</value>
|
|
// </prop>
|
|
// </item>
|
|
//
|
|
// Another example:
|
|
// [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.Office.OptionsDialog\OptionsDialogGroups\ProductName/#fuse\Pages\Java/#fuse\Hide]
|
|
// "Value"="true"
|
|
// becomes the following in configuration:
|
|
// <!-- Hide Tools - Options - LibreOffice - Advanced panel -->
|
|
// <item oor:path="/org.openoffice.Office.OptionsDialog/OptionsDialogGroups">
|
|
// <node oor:name="ProductName" oor:op="fuse">
|
|
// <node oor:name="Pages">
|
|
// <node oor:name="Java" oor:op="fuse">
|
|
// <prop oor:name="Hide">
|
|
// <value>true</value>
|
|
// </prop>
|
|
// </node>
|
|
// </node>
|
|
// </node>
|
|
// </item>
|
|
//
|
|
// Third example (property of an extensible group -> needs type):
|
|
// [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.Office.Jobs\Jobs\org.openoffice.Office.Jobs:Job['UpdateCheck']\Arguments\AutoCheckEnabled]
|
|
// "Value"="false"
|
|
// "Final"=dword:00000001
|
|
// "Type"="xs:boolean"
|
|
// becomes the following in configuration:
|
|
// <item oor:path="/org.openoffice.Office.Jobs/Jobs/org.openoffice.Office.Jobs:Job['UpdateCheck']/Arguments">
|
|
// <prop oor:name="AutoCheckEnabled" oor:type="xs:boolean" oor:finalized="true">
|
|
// <value>false</value>
|
|
// </prop>
|
|
// </item>
|
|
//
|
|
// External (component data) example:
|
|
// [HKEY_CURRENT_USER\Software\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
|
|
// "Value"="company"
|
|
// "Final"=dword:00000001
|
|
// "External"=dword:00000001
|
|
// "ExternalBackend"="com.sun.star.configuration.backend.LdapUserProfileBe"
|
|
// becomes the following in configuration:
|
|
// <item oor:path="/org.openoffice.UserProfile/Data">
|
|
// <prop oor:name="o" oor:finalized="true">
|
|
// <value oor:external="com.sun.star.configuration.backend.LdapUserProfileBe company"/>
|
|
// </prop>
|
|
// </item>
|
|
//
|
|
// Nil example:
|
|
// Empty value (<value></value>) and nil value (<value xsi:nil="true"/>) are different.
|
|
// In case of some path settings, the base path setting has to be cleared.
