XML_OPTION_SKIP_WHITE bool Whether to skip values consisting of whitespace characters.
XML_OPTION_TARGET_ENCODING string Sets which target encoding to use in this XML parser.By default, it is set to the same as the source encoding used by xml_parser_create(). Supported target encodings are ISO-8859-1, US-ASCII and UTF-8.

Rückgabewerte
