xmllint - command line XML tool SYNOPSIS
xmllint [--version | --debug | --shell | --debugent | --copy | --recover | --noent | --noout | --htmlout | --nowrap | --valid | --postvalid | --dtdvalid URL | --timing | --repeat | --insert | --compress | --sgml | --html | --push | --memory | --nowarning | --noblanks | --format | --testIO | --encode encoding | --catalogs | --nocatalogs | --auto | --xinclude | --loaddtd | --dtdattr | --dropdtd | --stream | --chkregister] [xmlfile] 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. Details on available commands 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 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. --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. SHELL
xmllint 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. AUTHORS
