       xmllint --help

       The xmllint program parses one or more XML files, specified on the
       command line as XML-FILE (or the standard input if the filename
       provided is - ). 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.

       xmllint is included in libxml(3).

       xmllint accepts the following options (in alphabetical order):

       --auto Generate a small document for testing purposes.

	      Use the SGML catalog(s) from SGML_CATALOG_FILES. Otherwise XML
	      catalogs starting from /etc/xml/catalog are used by default.

	      Turn on node registration. Useful for developers testing
	      libxml(3) node tracking code.

	      Turn on gzip(1) compression of output.

       --copy Test the internal copy implementation.

       --c14n Use the W3C XML Canonicalisation (C14N) to serialize the result
	      of parsing to stdout. It keeps comments in the result.

       --dtdvalid URL
	      Use the DTD specified by an URL for validation.

       --dtdvalidfpi FPI
	      Use the DTD specified by a Formal Public Identifier FPI for
	      validation, note that this will require a catalog exporting that
	      Formal Public Identifier to work.

	      Parse a file and output an annotated tree of the in-memory
	      version of the document.

	      Debug the entities defined in the document.

	      Remove DTD from output.

	      Fetch external DTD and populate the tree with inherited

       --encode ENCODING
	      Output in the given encoding.

	      Reformat and reindent the output. The XMLLINT_INDENT environment
	      variable controls the indentation. The default value is two
	      spaces " ").

       --help Print out a short usage summary for xmllint.

       --html Use the HTML parser.

	      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/viewed in a browser.

	      Test for valid insertions.

	      Fetch an external DTD.

	      Display all the documents loaded during the processing to

       --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.

	      Parse from memory.

	      Drop ignorable blank spaces.

	      Do not use any catalogs.

	      Substitute CDATA section by equivalent text nodes.

	      Substitute entity values for entity references. By default,
	      xmllint leaves entity references in place.

	      Do not use the Internet to fetch DTDs or entities.

	      Suppress output. By default, xmllint outputs the result tree.

	      Do not emit warnings from the parser and/or validator.

	      Do not output HTML doc wrapper.

	      Do XInclude processing but do not generate XInclude start and
	      end nodes.

	      Remove redundant namespace declarations.

       --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.

       --path "PATH(S)"
	      Use the (space- or colon-separated) list of filesystem paths
	      specified by PATHS to load DTDs or entities. Enclose
	      space-separated lists by quotation marks.

       --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.

	      Validate after parsing has completed.

       --push Use the push mode of the parser.

	      Output any parsable portions of an invalid document.

       --relaxng SCHEMA
	      Use RelaxNG file named SCHEMA for validation.

	      Repeat 100 times, for timing or profiling.

       --schema SCHEMA
	      Use a W3C XML Schema file named SCHEMA for validation.

	      Run a navigating shell. Details on available commands in shell
	      mode are below (see the section called “SHELL COMMANDS”).

	      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.

	      Test user input/output support.

	      Output information about the time it takes xmllint to perform
	      the various steps.

	      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.

	      Display the version of libxml(3) used.

	      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 an existing in-memory tree. Used for

	      Do XInclude processing.

	      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.

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

       base   Display XML base of the node.

       bye    Leave the shell.

       cat NODE
	      Display the given node or the current one.

       cd PATH
	      Change the current node to the given path (if unique) or root if
	      no argument is given.

       dir PATH
	      Dumps information about the node (namespace, attributes,

       du PATH
	      Show the structure of the subtree under the given path or the
	      current node.

       exit   Leave the shell.

       help   Show this help.

       free   Display memory usage.

       load FILENAME
	      Load a new document with the given filename.

       ls PATH
	      List contents of the given path or the current directory.

       pwd    Display the path to the current node.

       quit   Leave the shell.

       save FILENAME
	      Save the current document to the given filename or to the
	      original name.

	      Check the document for errors.

       write FILENAME
	      Write the current node to the given filename.

	      SGML catalog behavior can be changed by redirecting queries to
	      the user's own set of catalogs. This can be done by setting the
	      SGML_CATALOG_FILES environment variable to a list of catalogs.
	      An empty one should deactivate loading the default
	      /etc/sgml/catalog catalog.

	      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

	      Setting the environment variable XML_DEBUG_CATALOG to non-zero
	      using the export command outputs debugging information related
	      to catalog operations.

	      Setting the environment variable XMLLINT_INDENT controls the
	      indentation. The default value is two spaces " ".

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