NAME

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

SYNOPSIS

       xmlcatalog [--shell | --create | --add type orig replace
		  | --del values | --noout | --verbose] [catalogfile]
		  [entities]

INTRODUCTION

	xmlcatalog is a command line application allowing users to monitor and manipulate XML and SGML catalogs. It is included in libxml2.

       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.

COMMAND LINE OPTIONS

       --shell filename
	      Run a shell allowing interactive queries on catalog file filename.

       --create filename
	      Create a new XML catalog. Outputs to stdout, ignoring filename unless --noout is used, in which case it creates a new  catalog  file
	      filename.

       --add 'type' 'orig' 'replace' filename
	      Add  an  entry  to  catalog file filename. type indicates the type of entry. Possible types are 'public', 'system', 'rewriteSystem',
	      'delegatePublic', 'delegateSystem'amd 'rewriteURI'. '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 filename, outputing 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.

	      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.

       --del 'values' filename
	      Remove  entries from the catalog file filename matching 'values'. The --del option will not overwrite filename, outputing to stdout,
	      unless --noout is used.

       --noout
	      Save output to the named file rather than outputing to stdout.

       --sgml Uses SGML Super catalogs for --add and --del options

       -v or --verbose
	      output debugging information.

SHELL COMMANDS

       Invoking xmlcatalog with the --shell  filename option opens a command line shell allowing interactive access to the catalog file identified
       by filename. Invoking the shell provides a command line prompt after which commands can be entered.

       public 'PublicID'
	      Execute a public identifier lookup of the catalog entry for 'PublicID'. The corresponding entry will be output to the command line.

       system 'SystemID'
	      Execute a public identifier lookup of the catalog entry for 'SystemID'. The corresponding entry will be output to the command line.

       add  'type' 'orig' 'replace'
	      Add  an  entry to the catalog file. type indicates the type of entry. Possible types are 'public', 'system', 'rewriteSystem', 'dele-
	      gatePublic' and 'delegateSystem'. 'orig' is the original reference to be replaced, and 'replace'	is  the  URI  of  the  replacement
	      entity to be used.

       del 'values'
	      Remove the catalog entry corresponding to 'values'.

       dump   Print the current catalog.

       debug  Print debugging statements showing the steps xmlcatalog is executing.

       quiet  Stop printing debugging statements.

       exit   Quit the shell.

RETURN VALUES

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

       0: normal

       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 lookup and entry in the catalog
