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, 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-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.

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.

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, 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.

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 lookup 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 lookup 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
           space-separated list of catalogs. Use percent-encoding to escape spaces or other
           characters. An empty variable 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
