Comments

The script function opens an XML document for processing purposes. This can be the structured documentation or the report of an SAP job.

In order to add further descriptions and explanations, you can use tabs for documentation purposes. You can define them for the individual object types in the variable UC_OBJECT_DOCU. The structured documentation is a specific type of description which is characterized by a preceding "@". Structured documentation can be processed with specific script elements.

Reports of SAP jobs are stored as XML documents. For XI_GET_CHANNEL, they contain a list of selected communication channels.

The return code of this script function is a handle which refers to the XML document. Some script elements that are used to process the XML document use this handle as a parameter.

You can close the XML document by using XML_CLOSE.

You cannot open more than one XML document at a time.

Examples

In this example, the Details tab of the object MM.DAY is opened for further processing.

:SET &XMLDOCU# = XML_OPEN(DOCU,"MM.DAY", "@Details")

This example opens an XML document with a string.

:set &ref# = xml_open('STRING','<xmlstring>')
:set &ref# = sys_last_err_nr()
:if &ret > 0
: set &txt# = sys_last_err_ins()
! implement error handling here
:endif

A bad XML string either leads to run time error, or returns a return code which can be read with sys_last_err_nr().
