Field Summary

static java.lang.String

DOCTYPE the DTD for the output

Constructor Summary

XMLExemplars()
initializes the object

XMLExemplars(milk.core.Exemplars exemplars)
initializes the object with the given exemplars

XMLExemplars(weka.core.Instances instances)

Method Summary

java.lang.String	getDateFormat() returns the date format used in the DATE attributes
java.lang.String	getDoctype() returns the DTD used in the XML file
milk.core.Exemplars	getExemplars() returns the current exemplars object (either read or set)
java.lang.String	getPI() returns the processing instructions to use in the file
static void	main(java.lang.String[] args) for testing only (first arg type [xml/arff], second arg filename)
milk.core.Exemplars	process(Document doc) transforms an XML document into an exemplars object
Document	process(milk.core.Exemplars exemplars) transforms Exemplars into an XML document
boolean	read(java.lang.String filename) reads the exemplars from the given XML file, returns TRUE if successful
void	setDateFormat(java.lang.String dateFormat) sets the date format to use in the attributes
void	setDoctype(java.lang.String doctype) sets the DTD to use in XML file
void	setExemplars(milk.core.Exemplars exemplars) sets the exemplars object to use
void	setInstances(weka.core.Instances instances) sets the instances object to use, assumes that the first attribute is the bag for creating an exemplars object
void	setPI(java.lang.String pi) sets the processing instructions to use in the file
static int	stringToType(java.lang.String typeStr) returns the WEKA Attribute type of the given string, default is STRING
static java.lang.String	typeToString(int type) returns a string representation of the given WEKA Attribute type, default is TYPE_STRING
boolean	write(java.lang.String filename) writes the current exemplars to the given filename, returns TRUE if successful
static boolean	write(java.lang.String filename, milk.core.Exemplars exemplars) writes the given exemplars to the given file, in XML format, returns TRUE if successful
static boolean	write(java.lang.String filename, weka.core.Instances instances) writes the given instances to the given file, in XML format, returns TRUE if successful.
