INTRODUCTION
The xmllint program parses one or more XML files, speci-
fied 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 com-
mands 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 docu-
ment.
--noent
Substitute entity values for entity references. By
default, xmllint leaves entity references in place.
--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.
--timing
Output information about the time it takes xmllint
to perform the various steps.
--repeat
Repeat 100 times, for timing or profiling.
--insert
Test for valid insertions.
--compress
Turn on gzip compression of output.
--sgml Use the DocBook SGML parser. This allows documents
written in SGML DocBook to be converted into an in-
memory tree and treated as if they were written in
XML.
--html Use the HTML parser.
--push Use the push mode of the parser.
--memory
Parse from memory.
--nowarning
Do not emit warnings from the parser and/or valida-
tor.
--noblanks
Drop ignorable blank spaces.
--format
Reformat and reindent the output.
--testIO
Test user input/output support.
--encode encoding
Output in the given encoding.
--catalogs
Use the catalogs from $SGML_CATALOG_FILES. Other-
wise /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.
--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 for validation of files
that are too large to be held in memory.
--chkregister
Turn on node registration. Useful for developeres
testing libxml2 node tracking code.
SHELLxmllint 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
Dumps information about the node (namespace,
attributes, content).
du path
Show the structure of the subtree under path or the
current node.
exit Leave the shell.
help Show this help.
free Display memory usage.
load name
Load a new document with the given name.
ls path
List contents of path (if given) or the current
directory.
pwd Display the path to the current node.
quit Leave the shell.
save name
Saves the current document to name if given or to
the original name.
validate
Check the document for error.
write name
Write the current node to the given filename.
DEBUGGING CATALOGS
Setting the environment variable XML_DEBUG_CATALOG using
the command "export XML_DEBUG_CATALOG=" outputs debugging
information related to catalog operations.
