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', 'uri', - 'rewriteSystem', 'rewriteURI', 'delegatePublic', 'delegateSystem', - 'delegateURI' and '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 - 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', 'uri', 'rewriteSystem', 'rewriteURI', - 'delegatePublic', 'delegateSystem', 'delegateURI' and 'nextCatalog'. '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

Catalogs

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 default catalog.

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 list + of catalogs. An empty one should deactivate loading the + default /etc/xml/catalog catalog. +

DIAGNOSTICS

Introduction

- The xmllint program parses one or more XML files, specified on the - command line as xmlfile. It prints various - types of output, depending upon the options selected. It is useful for - detecting errors both in XML code and in the - XML parser itself. -

- It is included in libxml2. -

Options

--version
- Display the version of - libxml2 used. -
--debug
- Parse a file and output an annotated tree of the - in-memory version of the document. -
--shell
- Run a navigating shell. Details on available commands in shell mode - are below. -
--debugent
- Debug the entities defined in the document. -
--copy
- Test the internal copy implementation. -
--recover
- Output any parsable portions of an invalid - document. -
--noent
- Substitute entity values for entity - references. By default, xmllint leaves entity - references in place. -
--nocdata
- Substitute CDATA section by equivalent text nodes. -
--nsclean
- Remove redundant namespace declarations. -
--noout
- Suppress output. By default, - xmllint outputs the result tree. -
--htmlout
- Output results as an HTML - file. This causes xmllint to output - the necessary HTML tags surrounding the result tree - output so the results can be displayed in a browser. -
--nowrap
- Do not output HTML doc wrapper. -
--valid
- Determine if the document is a valid instance - of the included Document Type Definition (DTD). A - DTD to be validated against also can be specified at - the command line using the --dtdvalid option. By default, - xmllint also checks to determine if the - document is well-formed. -
--postvalid
- Validate after parsing is completed. -
--dtdvalid URL
- Use the - DTD specified by URL for - validation. -
--dtdvalidfpi FPI
- Use the - DTD specified by the Public Identifier - FPI for validation, note that this - will require a Catalog exporting that Public Identifier to work. -
--timing
- Output information about the time it takes - xmllint to perform the various steps. -
--output file
Define a file path where xmllint will save the result of - parsing. Usually the programs build a tree and save it on stdout, with - this option the result XML instance will be saved onto a file.
--repeat
- Repeat 100 times, for timing or profiling. -
--insert
- Test for valid insertions. -
--compress
- Turn on gzip compression of output. -
--html
- Use the HTML parser. -
--xmlout
Used in conjunction with --html. Usually - when HTML is parsed the document is saved with the HTML serializer, but with - this option the resulting document is saved with the XML serializer. This is - primarily used to generate XHTML from HTML input.
--push
- Use the push mode of the parser. -
--memory
- Parse from memory. -
--maxmem nnbytes
Test the parser memory - support. nnbytes is the maximum number of bytes the - library is allowed to allocate. This can also be used to make sure batch - processing of XML files will not exhaust the virtual memory of the server - running them.
--nowarning
- Do not emit warnings from the parser and/or validator. -
--noblanks
- Drop ignorable blank spaces. -
--format
- Reformat and reindent the output. The $XMLLINT_INDENT - environment variable controls the indentation (default - value is two spaces " "). -
--testIO
- Test user input/output support. -
--encode encoding
- Output in the given encoding. -
--catalogs
- Use the catalogs from $SGML_CATALOG_FILES. Otherwise /etc/xml/catalog - is used by default. -
--nocatalogs
- Do not use any catalogs. -
--auto
- Generate a small document for testing purposes. -
--xinclude
- Do XInclude processing. -
--noxincludenode
- Do XInclude processing but do not generate XInclude start and end - nodes. -
--loaddtd
- Fetch external DTD. -
--dtdattr
- Fetch external DTD and populate the tree with inherited attributes. -
--dropdtd
- Remove DTD from output. -
--stream
Use streaming API - useful when used in combination with - --relaxng or --valid options for validation of files that are - too large to be held in memory.
--walker
Test the walker module, which is a reader interface but for a - document tree, instead of using the reader API on an unparsed document it - works on a existing in-memory tree. Used in debugging.
--chkregister
Turn on node registration. Useful for developers testing - libxml2 node tracking code.
--pattern patternvalue
Used to exercise the pattern recognition engine, which can be - used with the reader interface to the parser. It allows to select some - nodes in the document based on an XPath (subset) expression. Used for - debugging.
--relaxng schema
Use RelaxNG file named schema for - validation.
--schema schema
Use a W3C XML Schema file named schema for validation.
- --c14n
Use the W3C XML Canonicalisation (C14N) to -serialize the result of parsing to stdout. It keeps comments in -the result.

Shell

- xmllint offers an interactive shell mode - invoked with the --shell command. Available commands in - shell mode include: -

base
- display XML base of the node -
bye
- leave shell -
cat node
- Display node if given or current node. -
cd path
- Change the current node to path (if given - and unique) or root if no argument given. -
dir path
