Accessing the XML structre of an InDesign^® document.

You will find a general example for the use of xml here.

Text or frame of a document can be linked with XML elements. The methods of the module permit access to these elements.

1. If the script has its own XML element, this will be used. This criterium is only fulfilled by scripts which are triggered by XML Link.
2. If a text model is defined (textmodel::available) and is linked with an XML element, this element will be used.
3. If a frame is defined (gFrame != 0) and is linked with an XML element, this element will be used.
4. Use the root element of the document

static int set_document_attribute(

static int export_(
  DBC dbc,
  char* selectCmd,
  char* xmlPath,
  char* filename,
  char* root = "",
  char* parent = "",
  int lowerCase = 1)

General data export from the database in XML. The files will be created in the following format

<root>
 	<parent>
 		<ATTR>
 		</ATTR>
 		<!-- ... -->
 	</parent>
 	<!-- ... -->
</root>

The names for the root and the respective parent elements will either be ascertained from the file name or may be assigned as a parameter of the function. If the identifiers are ascertained, the file name will be used as the root name minus the file extension and as the parent name of the root name minus a letter.
If the file name is panelstatements.xml, the root element panelstatements will be named and the parent element in each case is called panelstatement.

The elements of the export are called the same as the columns of the Selects. With Oracle the columns names will be automatically delivered in upper case. The name can during export be converted into lowercase (Parameter lowerCase). If the name contains characters which do not comply with the XML identifier convention, these characters will be converted into underscores (_). Strings can be directly inserted in the Select for nesting the XML elements. Here is an example:

select a.id, '<Type>', d.id, d.name, '</Type>', a.name from ...

creates the following output for example

<id>123</id>
<Type>
 	<id>1</id>
 	<name>Type-name</name>
<Type>
<name>kahsgd<name>

Binary data of the database (BLOB) is exported in files. For the target in each case the subfolder filename/attribute will be used. This folder will be automatically created. For the file name, the ID of the dataset will be used. In the XML folder, the local path to the export file will be entered as XML attribute src so for example

<preview src='pageitems/preview/12.gif'></preview>.

For the folder names the conversion for the element names as previously described will be used.
In order that during the export the correct file types (file extensions for Windows, file types and creator and/or file extension for Mac OSX) will be created, classifications between table attributes and file extensions can be made.
For the export of constants such as select id, 1401, ..., for example, a column must be specified. Moreover, the value must be converted so that not decimal number is returned, because Oracle internally recognised such columns as decimal numbers :
select id, to_char (1401)"id2", ....

the classification between file extension and type/creator with Mac OSX is undertaken automatically in accordnace with the following listing.

File extension	Type	Creator	Program
indd	IDd3	InDn	InDesign®
psd	8BIM	8BIM	Photoshop
psd	8BPS

Name	Type	Default	Description
Return	int		0 or ErrorCode
dbc	DBC	0	Database from which the export is to be made 0 : Use the current database connection
selectCmd	String or char*	-	Complete select instruction for ascertaining the data which is to be exported. In order that the names of the XML elements are unique, you should give names to the outpu columns of the select select c.name"color name", ... Special characters, points, empty spaces, ... will be replaced by '_' in the identifiers.
xmlpath	String or char*	""	entry path for the export. Empty string : The current path of the XML data will be used, see xmlquery::app_path
filename	String or char*	""	Name of the XML folders and the element in which the data is to be stored. The data name must have an extension (if possible .xml).
root	String or char*	"root"	Name of the root element of the XML folder Empty string : Use the name of the XML folder with file extension
parent	String or char*	""	Name of the element in which the data is to be stored Empty string : use the name of the XML folder with file extension and without the final letter (hopefully the s of the English plural.)
lowerCase	int	1	Are the names of the database attributes to be displayed in lower case? 1 : Use lowercase otherwise : Uppercase for the attribute names, column names in the select select (in double quotations after the attribute) remain unchanged.
attrXformat	String or char*	""	Allocations between table columns and file extensions consist of comma separated pairs attribute name file ending (without period), e.g. "Preview gif, Data indd". Empty string : All data will be exported in binary files (.bin).

Export some fields of the table panelstatements. The root element of the XML folder is called panelstatements. Data is written in each case in elements with the name panelstatement.

xml::export_ (
 	0,
 	"select id, description, statement from panelstatements where id > 0",
 	"",	// path from InDesign®
 	"panelstatements.xml");

Export some fields of the table panelstatements. The root element of the XML folder is called ROOT. Data is written in each case in elements with the name ENTRY. The database attribute panelstatements.description creates XML elements with the name description

xml::export_
 	0,
 	"select id, description\"Beschreibung\", statement from panelstatements where id > 0",
 	"",
 	"panelstatements.xml",
 	"ROOT",
 	"ENTRY");

xml::export 
 	0,
 	"select id, description, statement from panelstatements where id > 0",
 	"",	// path from InDesign®
 	"panelstatements.xml");

In order to export all values of a table, the asterisk * can be used to description the table attributes.Bear in mind that the name of all attributes are displayed in uppercase.

xml::export_ (
 	0,
 	"select *  from panelstatements where id >0",
 	"",
 	"panelstatements.xml")

Export all data of the table pageitems. In doing so the previews will be stored as gif images and the data will be stored as InDesign^® files.

xml::export_ (
 	0,
 	"select * from pageitems where id >0",
 	"",	// path from InDesign®
 	"pageitems.xml",
 	"",	// root <pageitems>
 	"",	// parent <pageitem>
 	1,	// lower case names
 	"Data indd, Preview gif")));
