Comments

Use this script function in order to read an element's text in an XML document.

The script function requires a reference to be able to access the element. This reference is provided by script elements which can be positioned within the XML document (such as XML_GET_FIRST_CHILD, XML_GET_NEXTSIBLING, XML_SELECT_NODE or XML_OPEN).

The content of a text attribute may be retrieved using the script function XML_GET_ATTRIBUTE.

There is no limit for the returned value.

Examples

The text "Related objects:" of the Objects element is written to the activation protocol in the example shown below.

:SET &XMLDOCU# = XML_OPEN(DOCU,"ON_CALL","@Details")

:
SET &HND# = XML_GET_FIRST_CHILD(&XMLDOCU#)
:
SET &HND# = XML_GET_FIRST_CHILD(&HND#)

:
WHILE &HND# <> ""
:    
  SET &NAME# = XML_GET_NODE_NAME(&HND#)
:      
SET &TXT# = XML_GET_NODE_TEXT(&HND#)
