To run DOMPrint, enter the following:</p> <source>DOMPrint <XML file></source> <p>The following parameters may be set from the command line </p> <source> Usage: DOMPrint [options] <XML file> This program invokes the DOM parser, and builds the DOM tree It then asks the DOMWriter to serialize the DOM tree. Options: -e create entity reference nodes. Default is no expansion. -v=xxx Validation scheme [always | never | auto*]. -n Enable namespace processing. Default is off. -s Enable schema processing. Default is off. -f Enable full schema constraint checking. Defaults is off. -wenc=XXX Use a particular encoding for output. Default is the same encoding as the input XML file. UTF-8 if input XML file has not XML declaration. -wfile=xxx Write to a file instead of stdout. -wscs=xxx Enable/Disable split-cdata-sections. Default on. -wddc=xxx Enable/Disable discard-default-content. Default on. -wflt=xxx Enable/Disable filtering. Default off. -wfpp=xxx Enable/Disable format-pretty-print. Default off. -wbom=xxx Enable/Disable write Byte-Order-Mark Default off. -? Show this help * = Default if not provided explicitly. The parser has intrinsic support for the following encodings:\n" UTF-8, USASCII, ISO8859-1, UTF-16[BL]E, UCS-4[BL]E,\n" WINDOWS-1252, IBM1140, IBM037, IBM1047.\n" </source> <p><em>-v=always</em> will force validation<br/> <em>-v=never</em> will not use any validation<br/> <em>-v=auto</em> will validate if a DOCTYPE declaration or a schema declaration is present in the XML document</p> <p>Here is a sample output from DOMPrint</p> <source>cd &XercesCInstallDir;-linux/samples/data DOMPrint -v=always personal.xml <?xml version="1.0" encoding="iso-8859-1"?> <!DOCTYPE personnel SYSTEM "personal.dtd"> <!-- @version: --> <personnel> <person id="Big.Boss"> <name><family>Boss</family> <given>Big</given></name> <email>chief@foo.com</email> <link subordinates="one.worker two.worker three.worker four.worker five.worker"></link> </person> <person id="one.worker"> <name><family>Worker</family> <given>One</given></name> <email>one@foo.com</email> <link manager="Big.Boss"></link> </person> <person id="two.worker"> <name><family>Worker</family> <given>Two</given></name> <email>two@foo.com</email> <link manager="Big.Boss"></link> </person> <person id="three.worker"> <name><family>Worker</family> <given>Three</given></name> <email>three@foo.com</email> <link manager="Big.Boss"></link> </person> <person id="four.worker"> <name><family>Worker</family> <given>Four</given></name> <email>four@foo.com</email> <link manager="Big.Boss"></link> </person> <person id="five.worker"> <name><family>Worker</family> <given>Five</given></name> <email>five@foo.com</email> <link manager="Big.Boss"></link> </person> </personnel></source> <p>Note that DOMPrint does not reproduce the original XML file.
