Comments

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

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

Structured documentation distinguishes the attribute types "text" and "listing", both of which may be read using XML_GET_ATTRIBUTE.

There is no limit for the returned value.

Examples

The example shown below retrieves the values of the attributes "Name" (enumeration type) and "Title" (text type). The contents "Smith" and "on call 2012" are written to the activation protocol.

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

: SET &HND# = XML_GET_FIRST_CHILD(&XMLDOCU#)
: SET &HND# = XML_GET_NEXTSIBLING(&HND#)
: SET &NAME# = XML_GET_ATTRIBUTE(&HND#, "@Name")
: PRINT "attribute value: &NAME#"
: SET &TITLE# = XML_GET_ATTRIBUTE(&HND#, "@Title")
: PRINT "attribute value: &TITLE#"

:XML_CLOSE
