Discussion

%XML_ELEM_SETATTRIBUTE looks for an XML attribute by name. If it finds it, it updates the attribute’s value. If it cannot find the attribute, it adds a new attribute to the element’s attribute list using the specified name and value.

In the XML document, attributes are written in an element’s start tag after the tag name, beginning with the name of the attribute, followed by an equal sign (=) and a value for the attribute. For example, in

<structure name="mystruct" >

name = “mystruct” is the attribute and its value.

This function is defined as ^VAL.
