The PBDOM_EXCEPTION class is derived from the PowerBuilder Exception class.
This class extends the Exception class with one method that returns the unique code that identifies the exception being thrown:
Returns the code of the exception being thrown.
pbdom_exception.GetExceptionCode()
Argument |
Description |
|---|---|
pbdom_exception |
The name of a PBDOM_EXCEPTION object |
Long. The code value associated with the exception being thrown.
In this example, an attempt to call the PBDOM_ELEMENT GetAttribute method on the root element of a PBDOM_DOCUMENT with the parameter xmlns:nuskin causes an exception to be thrown, because the name is not a valid NCName (no-colon-name). The correct way to get an attribute that belongs to a namespace is to use the namespace version of the PBDOM_ELEMENT GetAttribute method.The EXCEPTION_INVALID_NAME (code value 11) exception is thrown and is displayed in a message box :
PBDOM_DOCUMENT pbdom_doc1
PBDOM_DOCUMENT pbdom_get_doc
PBDOM_ELEMENT pbdom_elem_root
PBDOM_ATTRIBUTE pbdom_attr
PBDOM_OBJECT pbdom_obj
try
pbdom_doc1 = Create PBDOM_DOCUMENT
pbdom_doc1.NewDocument("nuskin", &
"http://www.nuskin.com", "nuskin:root", "", "")
pbdom_elem_root = pbdom_doc1.GetRootElement()
pbdom_attr = &
pbdom_elem_root.GetAttribute("xmlns:nuskin")
catch (PBDOM_EXCEPTION pbdom_except)
MessageBox ("Exception", "Code : " &
+ string(pbdom_except.GetExceptionCode()) &
+ "~r~nText : " + pbdom_except.Text)
end try
