XML

Constante	Tipo	Valor	Comentário
Copy XML data source	Inteiro longo	1	4D keeps a copy of the DOM tree with the picture, which means the picture can be saved in a picture field of the database and then redisplayed or exported at any time.
DOCTYPE Name	Inteiro longo	3	Name of the root element as defined in the DOCTYPE marker
Document URI	Inteiro longo	6	URI of the DTD
Encoding	Inteiro longo	4	Encoding used (UTF-8, ISO...)
Get XML data source	Inteiro longo	0	4D only reads the XML data source; it is not kept with the picture. This noticeably increases command execution speed; however, because the DOM tree is not kept, it is not possible to store or export the picture.
Own XML data source	Inteiro longo	2	4D exports the DOM tree with the picture. The picture can be stored or exported and command execution is fast. However, the elementRef XML reference can then no longer be used by other 4D commands. This is the default mode for exporting when the exportType parameter is omitted.
PUBLIC ID	Inteiro longo	1	Public identifier (FPI) of the DTD to which the document conforms (if the DOCTYPE xxx PUBLIC tag is present).
SYSTEM ID	Inteiro longo	2	System identifier
Version	Inteiro longo	5	Accepted XML version
XML Base64	Inteiro longo	1
XML binary encoding	Inteiro longo	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 case insensitive	Inteiro longo	2
XML case sensitive	Inteiro longo	1
XML CDATA	Inteiro longo	7
XML comment	Inteiro longo	2
XML convert to PNG	Inteiro longo	1
XML DATA	Inteiro longo	6
XML data URI scheme	Inteiro longo	2
XML date encoding	Inteiro longo	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 datetime local	Inteiro longo	3
XML datetime local absolute	Inteiro longo	1
XML datetime UTC	Inteiro longo	5
XML DOCTYPE	Inteiro longo	10
XML DOM case sensitivity	Inteiro longo	8	Specifies the case sensitivity regarding element names for DOM Get XML element and DOM Count XML elements commands. Possible values: XML case sensitive (default value): commands are case sensitive. XML case insensitive: commands are not case sensitive.
XML duration	Inteiro longo	2
XML ELEMENT	Inteiro longo	11
XML end document	Inteiro longo	9
XML end element	Inteiro longo	5
XML entity	Inteiro longo	8
XML external entity resolution	Inteiro longo	7	Controla se as entidades externas são resolvidas em documentos XML. De forma pré-determinada, por razões de segurança, os analisadores XML DOM e SAX 4D não permitem a resolução de entidades externas. Valores possíveis: XML enabled: permite a resolução de entidades externas em documentos XML XML disabled (valor predeterminado): não permite a resolução de entidades externas (uma declaração de entidade externa gera um erro de análise)
XML indentation	Inteiro longo	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 ISO	Inteiro longo	1
XML local	Inteiro longo	2
XML native codec	Inteiro longo	2
XML no indentation	Inteiro longo	2
XML picture encoding	Inteiro longo	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 processing instruction	Inteiro longo	3
XML raw data	Inteiro longo	2
XML seconds	Inteiro longo	4
XML start document	Inteiro longo	1
XML start element	Inteiro longo	4
XML string encoding	Inteiro longo	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	Inteiro longo	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>".
