Script function: Adds a new attribute to an XML element or changes an existing one.
XML_SET_ATTRIBUTE (Element, Attribute, Value)
Reference to the element whose attribute will be changed or to which the new attribute will be added.
Name of the attribute proceeded by the '@' character
Important! Always include the @ character before the name of the attribute. If you omit this character, a runtime error will occur.
|Value||Value of the attribute
Format: script literal or script variable
'0' – The attribute was successfully changed/added.
The script element changes an attribute of an element that is located in the XML document that is open. Specify a reference to the element, and the name and value of the attribute.
- If the attribute you entered is not located, it will be added to the element again.
- The element will only be modified in the memory. The script element does not have an effect on the Documentation tab.
- Use the XML_OPEN script function to open the XML document. For more information, see XML_OPEN.
The following example opens a structured Documentation tab as an XML document and selects the 'Child' element. The new 'Attribute1' attribute will then be added to the element. If successfully added, the set attribute will then be read once more as a check and the value will be written to the activation log.
:IF &XMLDOCU# <> ""
:SET &ELEMENT# = XML_SELECT_NODE(&XMLDOCU#,"Child")
:SET &RET# = XML_SET_ATTRIBUTE(&ELEMENT#,"@Attribute1","Value1")
:IF &RET# = 0
:SET &ATT# = XML_GET_ATTRIBUTE(&ELEMENT#,"@Attribute1")
