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.

--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.

--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 validator.

--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. 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.

--loaddtd
    Fetch external DTD.

--dtdattr
    Fetch external DTD and populate the tree with inherited attributes.
