--autoGenerate a small document for testing purposes.
--catalogs
Use the SGML catalog(s) from SGML_CATALOG_FILES.
Otherwise XML catalogs starting
from /etc/xml/catalog or, more specifically,
${sysconfdir}/xml/catalog are used by default.
--compress
Turn on gzip(1) compression of output.
--copyTest 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.
--debug
Parse a file and output an annotated tree of the
in-memory version of the document.
--debugentDebug the entities defined in the document.
--dropdtdRemove DTD from output.
--dtdattr
Fetch external DTD and populate the tree with
inherited attributes.
--encode ENCODINGOutput in the given encoding. Note that this works for full document not fragments or result from XPath queries.
--format
Reformat and reindent the output. The XMLLINT_INDENT
environment variable controls the indentation. The default value is two
spaces " ").
--helpPrint out a short usage summary for xmllint.
--htmlUse the HTML parser.
--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/viewed in a browser.
--insertTest for valid insertions.
--loaddtdFetch an external DTD.
--load-trace
Display all the documents loaded during the processing
to stderr.
--max-ampl INTEGER
Set the maximum amplification factor which protects against
exponential entity expansion ("billion laughs"). The default value
is 5. Documents making heavy use of entity expansion may require a
higher value.
--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.
--memoryParse from memory.
--noblanksDrop ignorable blank spaces.
--nocatalogsDo not use any catalogs.
--nocdataSubstitute CDATA section by equivalent text nodes.
--nodict
Don't use dictionaries (parser option XML_PARSE_NODICT).
Only for debugging.
--noent
Substitute entity values for entity references. By default, xmllint
leaves entity references in place.
--nonet
Do not use the Internet to fetch DTDs or entities.
--noout
Suppress output. By default, xmllint outputs the result tree.
--nowarningDo not emit warnings from the parser and/or validator.
--nowrapDo not output HTML doc wrapper.
--noxincludenode
Do XInclude processing but do not generate XInclude start and end nodes.
--nscleanRemove 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.
--pedanticEnable additional warnings.
--postvalidValidate after parsing has completed.
--pushUse the push mode of the parser.
--quietDon't print informational messages to stderr.
--recoverOutput any parsable portions of an invalid document.
--relaxng SCHEMA
Use RelaxNG file named SCHEMA
for validation.
--repeatRepeat 100 times, for timing or profiling.
--schema SCHEMA
Use a W3C XML Schema file
named SCHEMA for validation.
--shell
Run a navigating shell. Details on available commands in shell mode
are below (see the section called “SHELL COMMANDS”).
--xpath "XPath_expression"
Run an XPath expression given as argument and print the
result. In case of a nodeset result, each node in the
node set is serialized in full in the output. In case
of an empty node set the "XPath set is empty" result
will be shown and exit code 11 will be returned..
This feature is EXPERIMENTAL. Implementation details can
change without futher notice.
--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.
--testIOTest user input/output support.
--timing
Output information about the time it takes xmllint to perform the
various steps.
--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.
--version
Display the version of libxml(3) used.
--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 an existing in-memory tree. Used for
debugging.
--xincludeDo XInclude processing.
--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.
