Description Usage Arguments Details Value Author(s) See Also Examples

This function controls the import of input data set.

1	xmlRead.default(xmlItem)

xmlItem

(XMLNode) Object of class XMLNode that defines the a list object and fullfills XSD definition 'xmlReadData_list'.

Based on the tag name of the input data definition in the XML file, the corresponding readXMLData_* function is called, whereby * is a placeholder for the data type definition in the XML scheme. For example, for XML definitions following the data.frame specification, a function readXMLData_data.frame <- function(xmlDataItem) is expected, which implements the XML parser for data.frames and returns the data as R object.

(data.frame) or (variable) or (vector) or a named list of all imported input datasets.
