xmlcatalog is a command line application allowing users to monitor and manipulate XML and SGML catalogs. It is included in libxml(3).
Its functions can be invoked from a single command from the command line, or it can perform multiple functions in interactive mode. It can operate on both XML and SGML files.
xmlcatalog accepts the following options (in alphabetical order):
--add
TYPE
ORIG
REPLACE
Add an entry to CATALOGFILE. TYPE
indicates the type of entry. Possible types are: public, system, uri, rewriteSystem, rewriteURI, delegatePublic, delegateSystem, delegateURI, nextCatalog. ORIG is the original
reference to be replaced, and REPLACE
is the URI of the replacement entity to be
used. The --add option will not overwrite
CATALOGFILE, outputting
to stdout, unless
--noout is used. The --add will
always take three parameters even if some of the XML
catalog constructs will have only a single argument.
--add FILENAME
If the --add option is used following
the --sgml option, only a single argument,
a FILENAME, is used. This is used to add
the name of a catalog file to an SGML supercatalog,
a file that contains references to other included SGML
catalog files.
--create
Create a new XML catalog. Outputs
to stdout,
ignoring filename unless --noout is
used, in which case it creates a new catalog
file filename.
--del VALUE(S)
Remove entries from CATALOGFILE
matching VALUE(S). The --del
option will not overwrite CATALOGFILE,
outputting to stdout,
unless --noout is used.
--noout
Save output to the named file rather than outputting
to stdout.
--no-super-updateDo not update the SGML super catalog.
--shell
Run a shell allowing interactive queries on catalog
file CATALOGFILE. For the set of available
commands see the section called “SHELL COMMANDS”.
--sgml
Uses SGML super catalogs for --add
and --del options.
-v, --verboseOutput debugging information.
Invoking xmlcatalog non-interactively without a designated action
(imposed with options like --add) will result in a lookup
of the catalog entry for ENTITIES in the
catalog denoted with CATALOGFILE. The
corresponding entries will be output to the command line. This mode of
operation, together with --shell mode and non-modifying
(i.e. without --noout) direct actions, allows for
a special shortcut of the void CATALOGFILE
specification (possibly expressed as "" in the shell
environment) appointing the default system catalog. That simplifies the
handling when its exact location is irrelevant but the respective built-in
still needs to be consulted.
Invoking xmlcatalog with
the --shell option opens
a command line shell allowing interactive access to the catalog file
identified by CATALOGFILECATALOGFILE. Invoking the shell
provides a command line prompt after which the following commands (described in
alphabetical order) can be entered.
add
TYPE
ORIG
REPLACE
Add an entry to the catalog file. TYPE
indicates the type of entry. Possible types are: public, system, uri, rewriteSystem, rewriteURI, delegatePublic, delegateSystem, delegateURI, nextCatalog. ORIG is the original
reference to be replaced, and REPLACE
is the URI of the replacement entity to be
used. The --add option will not overwrite
CATALOGFILE, outputting
to stdout, unless
--noout is used. The --add will
always take three parameters even if some of the XML
catalog constructs will have only a single argument.
debugPrint debugging statements showing the steps xmlcatalog is executing.
del VALUE(S)
Remove the catalog entry corresponding to VALUE(S).
dumpPrint the current catalog.
exitQuit the shell.
public PUBLIC-ID
Execute a Formal Public Identifier lookup of the catalog entry
for PUBLIC-ID. The corresponding entry will be
output to the command line.
quietStop printing debugging statements.
system SYSTEM-ID
Execute a Formal Public Identifier lookup of the catalog entry
for SYSTEM-ID. The corresponding entry will be
output to the command line.
XML_CATALOG_FILESXML catalog behavior can be changed by redirecting
queries to the user's own set of catalogs. This can be done by setting
the XML_CATALOG_FILES environment variable to a list
of catalogs. An empty one should deactivate loading the
default /etc/xml/catalog catalog.
xmlcatalog return codes provide information that can be used when calling it from scripts.
No error
Failed to remove an entry from the catalog
Failed to save to the catalog, check file permissions
Failed to add an entry to the catalog
