/images/arrow_right.png IGeneralNotificationManager::GetXML method
The GetXML method generates the XML infoset based either on the data of a new notification using the IGeneralNotificationRequest interface or based on the received and replied XML infoset. In both cases the XML generation attributes are applied on the infoset generation, the XML is then validated against the XSD schema, and finally stored as UTF8 file in the internal working directory. The full file name to this XML document is returned in the pbstrOutputFile output variable.

The XML file must be saved to a different location as all temporary XML files in the working directory are deleted before the COM module shuts down!

Note about encryption: an encrypted XML infoset can not be loaded successfully by LoadXML. Therefore, to build a local archive besides encrypted XML infoset call GetXML twice once with the lXMLGenerationAttributes = enGenerateWithoutEncryption

/images/arrow_right.png Calling argument description
[in] long lXMLGenerationAttributes This variable defines which principal parts of the XML generation should not be carried out even if the data for that part are defined. lXMLGenerationAttributes is a 32-bit integer where the possible excludes are values from the XMLGenerationAttributes data type and are ORed together to form the overall command.

This feature is necessary to generate different "flavors" of XML infosets without re-setting input data. For instance, an encrypted XML infoset for the "toEAN" entity can be produced and in a second call the XML infoset without encryption (lXMLGenerationAttributes = enGenerateWithoutEncryption) is requested for a local archive (that can be loaded back later!).

[out] BSTR *pbstrOutputFile The full file name (path + name) where the XML infoset is stored in UTF-8 mode.

The XML file must be saved to a different location as all temporary XML files in the working directory are deleted before the COM module shuts down!

[out] long *plValidationError lValidationError is filled with the validation error code returned by the MSXML-4 parser. A zero value indicates that the validation was successful.
[in, out] long *plTimestamp The timestamp of the XML document as epoch time (seconds elapsed since 1.1.1970) that is used as timestamp of the notification object reference from that point on.

In a reply situation the "old" timestamp of the received XML infoset is returned.

[out] IGeneralNotificationResponse **ppIGeneralNotificationResponse The IGeneralNotificationResponse interface allows to read back all currently loaded data.
The handle is NULL if an error occurred.
[out, retval] VARIANT_BOOL *pbStatus Return status of the method. If pbStatus is VARIANT_FALSE then an error occurred and GetAbortInfo should be called to retrieve the error string.
 
/images/arrow_right.png C/C++ return value
S_OK This value is returned if the function call was successful or if the return value of a boolean method signalling a true value. In this case the VARIANT_BOOL is set to VARIANT_TRUE.
S_FALSE This is the return value of a boolean method signalling a false return value. In this case the VARIANT_BOOL is set to VARIANT_FALSE.
E_name This value is returned if the function call was unsuccessful and an error exception was generated. Note that if you are using SmartPointers an exception is thrown under these conditions.
