update-xmlcatalog
UPDATE-XMLCATALOG(8) xml-core UPDATE-XMLCATALOG(8) NAME
update-xmlcatalog - maintain XML catalog files SYNOPSIS
update-xmlcatalog --add --root --package package --type type --id id update-xmlcatalog --del --root --package package --type type --id id update-xmlcatalog --add --package package --local local --type type --id id update-xmlcatalog --del --package package --local local --type type --id id update-xmlcatalog --add --local local --file file --type type --id id update-xmlcatalog --del --local local --file file --type type --id id update-xmlcatalog --help DESCRIPTION
update-xmlcatalog add entries to and removes entries from the root XML catalog file, a package XML catalog file or a local XML catalog file. OPTIONS
--add Adds the entry to the root XML catalog file, a package XML catalog file or a local XML catalog file. If the XML catalog file does not exist yet, it is automatically created. --del Deletes the entry from the root XML catalog file, the package XML catalog file or the local XML catalog file. A resulting empty XML catalog is not automatically deleted from the filesystem. --file file Indicates a local filename. --id id Indicates the XML catalog file entry identifier. --local local Indicates a local XML catalog file. --package package Indicates a package XML catalog file. --root Indicates the root XML catalog file. --type type Indicates the XML catalog file entry type (public, system, uri). --help Displays the usage information. NOTES
update-xmlcatalog is the de-facto standard tool to be used to maintain XML catalog files on a Debian system, similar to that update-catalog(8) is the standard tool to be used to main SGML catalog files on a Debian system. A Debian XML Policy document to this effect is currently under development. update-xmlcatalog and xmlcatalog(1) are incompatible. The former has an internal database of all the entries in all the XML catalog files it maintains and regenerates the indicated XML catalog file completely from scratch upon an update. The latter updates the indicated XML catalog file directly. This means that any change made to an XML catalog file using xmlcatalog(1) is overwritten the next time that XML catalog file is updated using update-xmlcatalog. SEE ALSO
