DESCRIPTION

Thexmllintprogram parses one or moreXMLfiles, specified on the command line asXML-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 inXMLcode and in theXMLparser itself.

xmllintis included inlibxml(3). 

OPTIONS

xmllintaccepts the following options (in alphabetical order):

--auto
Generate a small document for testing purposes.
--catalogs
Use theSGMLcatalog(s) fromSGML_CATALOG_FILES. OtherwiseXMLcatalogs starting from/etc/xml/catalogare used by default.
--chkregister
Turn on node registration. Useful for developers testinglibxml(3)node tracking code.
--compress
Turn ongzip(1)compression of output.
--copy
Test the internal copy implementation.
--c14n
Use the W3CXMLCanonicalisation (C14N) to serialize the result of parsing tostdout. It keeps comments in the result.
--dtdvalid URL
Use theDTDspecified by anURLfor validation.
--dtdvalidfpi FPI
Use theDTDspecified by a Formal Public IdentifierFPIfor 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.
--debugent
Debug the entities defined in the document.
--dropdtd
RemoveDTDfrom output.
--dtdattr
Fetch externalDTDand populate the tree with inherited attributes.
--encode ENCODING
Output in the given encoding.
--format
Reformat and reindent the output. TheXMLLINT_INDENTenvironment variable controls the indentation. The default value is two spaces " ").
--help
Print out a short usage summary forxmllint.
--html
Use theHTMLparser.
--htmlout
Output results as anHTMLfile. This causesxmllintto output the necessaryHTMLtags surrounding the result tree output so the results can be displayed/viewed in a browser.
--insert
Test for valid insertions.
--loaddtd
Fetch an externalDTD.
--load-trace
Display all the documents loaded during the processing tostderr.
--maxmem NNBYTES
Test the parser memory support.NNBYTESis the maximum number of bytes the library is allowed to allocate. This can also be used to make sure batch processing ofXMLfiles will not exhaust the virtual memory of the server running them.
--memory
Parse from memory.
--noblanks
Drop ignorable blank spaces.
--nocatalogs
Do not use any catalogs.
--nocdata
Substitute CDATA section by equivalent text nodes.
--noent
Substitute entity values for entity references. By default,xmllintleaves entity references in place.
--nonet
Do not use the Internet to fetchDTDs or entities.
--noout
Suppress output. By default,xmllintoutputs the result tree.
--nowarning
Do not emit warnings from the parser and/or validator.
--nowrap
Do not outputHTMLdoc wrapper.
--noxincludenode
Do XInclude processing but do not generate XInclude start and end nodes.
--nsclean
Remove redundant namespace declarations.
--output FILE
Define a file path wherexmllintwill save the result of parsing. Usually the programs build a tree and save it onstdout, with this option the resultXMLinstance will be saved onto a file.
--path "PATH(S)"
Use the (space- or colon-separated) list of filesystem paths specified byPATHSto loadDTDs 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.
--postvalid
Validate after parsing has completed.
--push
Use the push mode of the parser.
--recover
Output any parsable portions of an invalid document.
--relaxng SCHEMA
Use RelaxNG file namedSCHEMAfor validation.
--repeat
Repeat 100 times, for timing or profiling.
--schema SCHEMA
Use a W3CXMLSchema file namedSCHEMAfor validation.
--shell
Run a navigating shell. Details on available commands in shell mode are below (seethe section called lqSHELL COMMANDSrq).
--stream
Use streamingAPI- useful when used in combination with--relaxngor--validoptions for validation of files that are too large to be held in memory.
--testIO
Test user input/output support.
--timing
Output information about the time it takesxmllintto perform the various steps.
--valid
Determine if the document is a valid instance of the included Document Type Definition (DTD). ADTDto be validated against also can be specified at the command line using the--dtdvalidoption. By default,xmllintalso checks to determine if the document is well-formed.
--version
Display the version oflibxml(3)used.
--walker
Test the walker module, which is a reader interface but for a document tree, instead of using the readerAPIon an unparsed document it works on an existing in-memory tree. Used for debugging.
--xinclude
Do XInclude processing.
--xmlout
Used in conjunction with--html. Usually whenHTMLis parsed the document is saved with theHTMLserializer. But with this option the resulting document is saved with theXMLserializer. This is primarily used to generateXHTMLfromHTMLinput.
 

SHELL COMMANDS

xmllintoffers an interactive shell mode invoked with the--shellcommand. Available commands in shell mode include (in alphabetical order):

base
DisplayXMLbase 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, content).
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.
validate
Check the document for errors.
write FILENAME
Write the current node to the given filename.
 

ENVIRONMENT

SGML_CATALOG_FILES
SGMLcatalog behavior can be changed by redirecting queries to the user's own set of catalogs. This can be done by setting theSGML_CATALOG_FILESenvironment variable to a list of catalogs. An empty one should deactivate loading the default/etc/sgml/catalogcatalog.
XML_CATALOG_FILES
XMLcatalog behavior can be changed by redirecting queries to the user's own set of catalogs. This can be done by setting theXML_CATALOG_FILESenvironment variable to a list of catalogs. An empty one should deactivate loading the default/etc/xml/catalogcatalog.
XML_DEBUG_CATALOG
Setting the environment variableXML_DEBUG_CATALOGtonon-zerousing theexportcommand outputs debugging information related to catalog operations.
XMLLINT_INDENT
Setting the environment variableXMLLINT_INDENTcontrols the indentation. The default value is two spaces " ".
