<s1 title="Sample: DOMPrint">
<s2 title="DOMPrint"> <p>DOMPrint parses an XML file, constructs the DOM tree, and invokes DOMLSSerializer::write() to serialize the resultant DOM tree back to XML stream. </p>
<s3 title="Running DOMPrint">
<p>The DOMPrint sample parses an XML file, using either a validating or non-validating DOM parser configuration, builds a DOM tree, and then invokes DOMLSSerializer::write() to serialize the resultant DOM tree. 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 treeIt then asks the DOMLSSerializer 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, US-ASCII, 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 &XercesC3InstallDir;/samples/dataDOMPrint -v=always personal.xml

<p>Application needs to provide its own implementation of DOMErrorHandler (in this sample, the DOMPrintErrorHandler), if it would like to receive notification from the serializer in the case any error occurs during the serialization. </p>
<p>Application needs to provide its own implementation of DOMLSSerializerFilter (in this sample, the DOMPrintFilter), if it would like to filter out certain part of the DOM representation, but must be aware that thus may render the resultant XML stream invalid. </p>
<p>Application may choose any combination of characters as the end of line sequence to be used in the resultant XML stream, but must be aware that this may render the resultant XML stream ill formed. </p>
<p>Application may choose a particular encoding name in which the output XML stream should be, but must be aware that if unrepresentable in the encoding specified characters appear in the markup, it may force the serializer to terminate serialization prematurely, and thus no complete serialization would be done. </p>
<p>Application shall query the serializer first, before set any feature/mode(true, false), or be ready to catch exception if this feature/mode is not supported by the serializer. </p>
<p>Application needs to release the filter, error handler and format target objects created for the serialization. </p>
