XML GET OPTIONS


XML GET OPTIONS ( elementRef \| document ; selector ; value {; selector2 ; value2 ; ... ; selectorN ; valueN} )

Parameter	Type	Description
elementRef \| document	Text, DocRef	XML root element reference or Reference of open document
selector	Longint	Option to get
value	Longint	Current value of option

Description

The XML GET OPTIONS command is used to get the current value of one or more XML parameters for the current session and the current user.

In selector, pass a constant of the "XML" theme indicating the option to get. The current value of the option is returned in the value parameter:

Constant	Type	Value	Comment
XML binary encoding	Longint	5	Specifies the way binary data will be converted. Possible values: XML Base64 (default value): binary data are simply converted to Base64 XML data URI scheme: binary data are converted to Base64 and the "data:;base64" header is added. This format mainly allows a browser to automatically decode a picture, and is also required for the insertion of pictures. For more information, see http://en.wikipedia.org/wiki/Data_URI_scheme.
XML date encoding	Longint	2	Specifies the way 4D dates will be converted. For example, !01/01/2003! in the Paris time zone. Possible values: XML ISO (default value): use of the format xs:datetime without indication of time zone. Result: "2003-01-01". The time part, if it is present in the 4D value (via SQL) is lost. XML local: use of the format xs:date with indication of time zone. Result: "2003-01-01 +01:00". The time part, if it is present in the 4D value (via SQL) is lost. XML datetime local: use of the format xs:dateTime (ISO 8601). Indication of time zone. This format allows the time part to be kept, if it is present in the 4D value (via SQL). Result: "<Date>2003-01-01T00:00:00 +01:00</Date>". XML UTC: use of the format xs:date. Result: "2003-01-01Z". The time part, if it is present in the 4D value (via SQL) is lost. XML datetime UTC: use of the format xs:dateTime (ISO 8601). This format allows the time part to be kept, if it is present in the 4D value (via SQL). Result: "<Date>2003-01-01T00:00:00Z</Date>".
XML indentation	Longint	4	Specifies the indentation of the XML document. Possible values: XML with indentation (default value): the document is indented. XML no indentation: the document is not indented; its contents are placed in a single line.
XML picture encoding	Longint	6	Specifies the way pictures must be converted (before encoding in Base64). Possible values: XML convert to PNG (default value): pictures are converted to PNG before being encoded in Base64. XML native codec: pictures are converted in their first native storage CODEC before being encoded in Base64. You must use these options to encode SVG pictures (see example for the XML SET OPTIONS command).
XML string encoding	Longint	1	Specifies the way 4D strings are converted to element values. It does not concern the conversion to attributes for which XML imposes the use of escape characters. Possible values: XML with escaping (default value): conversion of 4D strings to XML element values with replacement of characters. The Text type data are automatically parsed so that forbidden characters (<&>’) are replaced by XML entities (&<> '"). XML raw data: 4D strings are sent as raw data; 4D does not carry out encoding or parsing. 4D values are converted if possible to XML fragments and inserted as a child of the target element. If a value cannot be considered as an XML fragment, it is inserted as raw data into a new CDATA node.
XML time encoding	Longint	3	Specifies the way 4D times are converted. For example, ?02/00/46? (Paris time). The encoding differs depending on whether you want to express a time or a duration. Possible values for times: XML datetime UTC: time expressed in UTC (Universal Time Coordinated). Note that conversion to UTC is automatic. Result: "<Duration>0000-00-00T01:00:46Z</Duration>". XML datetime local: time expressed with the time difference of the machine of the 4D engine. Result: "<Duration>0000-00-00T02:00:46+01:00</Duration>". XML datetime local absolute (default value): time expressed without indication of time zone. No modification of the value. Result: "<Duration>0000-00-00T02:00:46</Duration>". Possible values for durations: XML seconds: number of seconds since midnight; no modification of the value since it expresses a duration. Result: "<Duration>7246</Duration>". XML duration: duration expressed in compliance with XML Schema Part 2: Datatypes Second Edition. No modification of the value since it expresses a duration. Result: "<Duration>PT02H00M46S</Duration>".
