3 Algorithm Examples
The following example shows the WBXML encoding of a server response that contains a new contact and provides a byte-by-byte description of the encoding.
The following XML represents a server response to a request to create a new contact.
-
<?xml version="1.0" encoding="utf-8"?> <Sync xmlns="AirSync" xmlns:airsyncbase="AirSyncBase" xmlns:contacts="Contacts"> <Collections> <Collection> <Class>Contacts</Class> <SyncKey>2</SyncKey> <CollectionId>2</CollectionId> <Status>1</Status> <Commands> <Add> <ServerId>2:1</ServerId> <ApplicationData> <airsyncbase:Body> <airsyncbase:Type>1</airsyncbase:Type> <airsyncbase:EstimatedDataSize>0</airsyncbase:EstimatedDataSize> <airsyncbase:Truncated>1</airsyncbase:Truncated> </airsyncbase:Body> <contacts:FileAs>Funk, Don</contacts:FileAs> <contacts:FirstName>Don</contacts:FirstName> <contacts:LastName>Funk</contacts:LastName> <airsyncbase:NativeBodyType>1</airsyncbase:NativeBodyType> </ApplicationData> </Add> </Commands> </Collection> </Collections> </Sync>
The Exchange ActiveSync: WAP Binary XML (WBXML) Algorithm encodes this XML as the following WBXML encoding.
-
03 01 6A 00 45 5C 4F 50 03 43 6F 6E 74 61 63 74 73 00 01 4B 03 32 00 01 52 03 32 00 01 4E 03 31 00 01 56 47 4D 03 32 3A 31 00 01 5D 00 11 4A 46 03 31 00 01 4C 03 30 00 01 4D 03 31 00 01 01 00 01 5E 03 46 75 6E 6B 2C 20 44 6F 6E 00 01 5F 03 44 6F 6E 00 01 69 03 46 75 6E 6B 00 01 00 11 56 03 31 00 01 01 01 01 01 01 01
