API browser of hospitalMCDRequest440 COM module


/images/arrow_right.png IHospitalMCDRequestManager::GetXML method
The GetXML method generates the XML infoset based on the data of the IGeneralInvoiceRequest interface and the XML generation attributes, validates the XML against the XSD schema, and stores the XML content as UTF8 file in the internal working directory. The full file name to this XML document is replied 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!

As a migration help there is a patch implemented that allows to override the generation of the default V440 infosets. The method is enforced to natively produce V430 XML infosets without any loss of data by setting *plTimestamp= -223456780 as input value.

/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 and documents (lXMLGenerationAttributes = enGenerateWithoutEncryption | enGenerateWithoutDocuments) 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 topmost object reference from that point on.

If the timestamp for the topmost object reference was already set (e.g. to produce a copy) then this same timestamp is returned.

PATCH: to ease migration issues the method is enforced to generate XML infoset of type hospitalMCDRequest_430.xsd if and only if *plTimestamp= -223456780 as input value.

[out] BSTR *pbstrUsedSchema The full XSD name that was used to generate the XML infoset.

In a standard situation this would be hospitalMCDRequest_440.xsd. However, a downgrade to hospitalMCDRequest_430.xsd can be requested by using the *plTimestamp variable appropriately.

[out] IHospitalMCDResult **ppIHospitalMCDResult The IHospitalMCDResult interface handles that allows to get all loaded data back.
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.
