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 FILE

NAME

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, 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 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
