Description

• An XML string reader is filled with a byte string that contains XML data in XML 1.0 format and UTF-8 representation. This data is produced by the conversion of a text string from the current code page.

• The method SKIP_NODE is used to pass the XML data of the reader to an XML writer for the Binary XML format. This data is then read to binary_xml.

• The XML data in Binary XML format is passed to a further XML string reader and then transformed to an XOP writer.
