JadeXMLException Class

The JadeXMLException class is the transient class that defines behavior for exceptions that occur as a result of XML processing. The Exception class errorItem and extendedErrorText properties and the JadeXMLException class properties are used to describe the XML processing exception in more detail.

The constants provided by the JadeXMLException class are listed in the following table.

Constant	Value	Returned when you attempt to …
CannotParsePersistent	8910	Parse an XML document into a persistent object tree using the parseFile or parseFile method of the JadeXMLDocument class. This is not allowed. To parse persistent documents, you must use the JadeXMLDocumentParser class and set up a mapping of node.
DocTypeAlreadyDefined	8903	Add a document type declaration to an XML document and one exists already. An XML document can have only one document type declaration.
InvalidClassMapping	8909	Set an invalid mapping for a JadeXMLNode class. The mapping is used when instances are created during the parsing of an XML document.
InvalidHierarchyRequest	8905	Add a node to an XML document at an invalid position; for example, moving an element to before a document or attribute.
NullNode	8904	Pass a null node reference to an XML processing method and the parameter cannot be null; for example, specifying a null value as the destination position when moving a node in the document tree.
ParserCreateFailed	8900	Create an instance of the XML parsing engine that cannot be created.
ParserError	8901	Parse an XML document and an error occurs; for example, the document is not well-formed.
ParserNodeMismatch	8908	Access an XML parser object on a different node to the one that created the parser; for example, when a parser is opened on a client node and a server method attempts to use the parser, this exception is raised.
RootElementAlreadyDefined	8902	Add a root (top-level) element to an XML document and one exists already. An XML document must have a single root element.
StringToUTF8Failed	8906	Parse an XML document that cannot be converted from JADE native format to UTF8 format.
UTF8ToStringFailed	8907	Parse an XML document that cannot be converted from UTF8 format to JADE native format.

The properties defined in the JadeXMLException class are summarized in the following table.

Property	Contains the …
columnNumber	Column number of text where the exception occurred
fileName	Name of the file where the exception occurred
lineNumber	Line number of text where the exception occurred
