Exporting to XML
388 InfoMaker
To specify how metadata should be saved, select a value from the Meta Data
Type drop-down list. The possible values are:
XMLNone!—No metadata is generated
XMLSchema!—An XML schema is generated
XMLDTD!—A DTD is generated
If the data item for a column is
null or an empty string, an empty element is
created. If you select XMLSchema!, child elements with
null data items are
created with the content
"xsi:nil='true'".
The metadata is saved into the exported XML itself or into an associated file,
depending on the setting in the SaveMeta Data drop-down list. The possible
values are:
MetaDataInternal!—The metadata is saved into the generated XML
document or string. To save metadata using the
.Data.XML expression
syntax, you must use this value.
MetaDataExternal!—The metadata is saved as an external file with the
same name as the XML document but with the extension .xsd (for a
schema) or .dtd (for a DTD). A reference to the name of the metadata file
is included in the output XML document.
Example: internal
metadata
For example, if you select XMLDTD! and MetaDataInternal!, the header and
first row of the exported XML would look like this for a simple grid report for
the
contact table in the EAS Demo DB. The Include Whitespace property has
also been selected and the file name is dtdinternal.xml:
<?xml version="1.0" encoding="UTF-16LE"
standalone="yes"?>
<!DOCTYPE dtdinternal [<!ELEMENT dtdinternal
(dtdinternal_row*)>
<!ELEMENT dtdinternal_row (id, last_name, first_name,
title, street, city, state, zip, phone, fax)>
<!ELEMENT id (#PCDATA)>
<!ELEMENT last_name (#PCDATA)>
<!ELEMENT first_name (#PCDATA)>
<!ELEMENT title (#PCDATA)>
<!ELEMENT street (#PCDATA)>
<!ELEMENT city (#PCDATA)>
<!ELEMENT state (#PCDATA)>
<!ELEMENT zip (#PCDATA)>
<!ELEMENT phone (#PCDATA)>
<!ELEMENT fax (#PCDATA)>
