XMLCATALOG(1) XMLCATALOG(1)

NAME
xmlcatalog - Command line tool to parse and manipulate XML or SGML catalog files.

SYNOPSIS
xmlcatalog [--sgml --shell --create --del VALUE(S) [ --add TYPE ORIG REPLACE --add FILENAME] --noout --no-super-update
[-v --verbose]] {CATALOGFILE} {ENTITIES...}

DESCRIPTION
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.

OPTIONS
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, rewriteSystem,
rewriteURI, delegatePublic, delegateSystem, 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-update
Do 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, --verbose
Output debugging information.

SHELL COMMANDS
Invoking xmlcatalog with the --shell CATALOGFILE option opens a command line shell allowing interactive access to the
catalog file identified by CATALOGFILE. 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,
rewriteSystem, rewriteURI, delegatePublic, delegateSystem, 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.

debug Print debugging statements showing the steps xmlcatalog is executing.

del VALUE(S)
Remove the catalog entry corresponding to VALUE(S).

dump Print the current catalog.

exit Quit the shell.

public PUBLIC-ID
Execute a Formal Public Identifier look-up of the catalog entry for PUBLIC-ID. The corresponding entry will be
output to the command line.

quiet Stop printing debugging statements.

system SYSTEM-ID
Execute a Formal Public Identifier look-up of the catalog entry for SYSTEM-ID. The corresponding entry will be
output to the command line.

ENVIRONMENT
XML_CATALOG_FILES
XML 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.

DIAGNOSTICS
xmlcatalog return codes provide information that can be used when calling it from scripts.

0 No error

1 Failed to remove an entry from the catalog

2 Failed to save to the catalog, check file permissions

3 Failed to add an entry to the catalog

4 Failed to look up an entry in the catalog
