status = %XML_ATTR_GETVALUE(attr, value[, length])
XML_SUCCESS if a nonblank value is returned.
The XML attribute instance to get a value for. (XML_ATTR_TYPE)
Returned with the value of the XML attribute. The maximum length is 65,022 characters. (a)
(optional) Returned with the length of the returned attribute value. The minimum length is 1, even if value is blank. (n)
This function is defined as ^VAL.
If you want to receive variable‑length data in a large buffer, we recommend using the length argument, as this will avoid time spent clearing the remainder of the buffer (beyond length) with spaces.
