Detailed Description

CXmlExample demonstrates the usage of the XML Framework to parse an XML and WBXML file.

CXmlExample implements the XML Framework's MContentHandler interface, which the parser calls to notify the application of parsing events, such as the start of elements.

Member Function Documentation

CXmlExample * CXmlExample::NewL ( ) [static]

Allocates and constructs a CXmlExample object. Initialises all member data to their default values.

Definition at line 68 of file xmlexample.cpp.

void CXmlExample::OnEndDocumentL ( TInt aErrorCode )

A callback to indicate the end of the document.

Implementation of the pure virtual function of MContentHandler.

Parameters:

aErrorCode

The error code. If aErrorCode is not KErrNone, the function leaves.

Definition at line 130 of file xmlexample.cpp.

void CXmlExample::OnContentL	(	const TDesC8 &	aData8,
		TInt	aErrorCode
	)

A callback that sends the content of the element and prints element content data to the console. Not all the content may be returned in one go. The data may be sent in chunks. When an OnEndElementL is received this means there is no more content to be sent.

Implementation of the pure virtual function of MContentHandler.

Parameters:

	aData8	The raw content data for the element. The client is responsible for converting the data to the required character set if necessary. In some instances the content may be binary and must not be converted.
	aErrorCode	The error code. If aErrorCode is not KErrNone, the function leaves.

Definition at line 228 of file xmlexample.cpp.

void CXmlExample::OnStartPrefixMappingL	(	const RString &	aPrefix,
		const RString &	aUri,
		TInt	aErrorCode
	)

A notification of the beginning of the scope of a prefix-URI Namespace mapping. Always called before the corresponding OnStartElementL method.

Implementation of the pure virtual function of MContentHandler.

Parameters:

	aPrefix	The Namespace prefix being declared.
	aUri	The Namespace URI the prefix is mapped to.
	aErrorCode	The error code. KErrNotSupported

Definition at line 300 of file xmlexample.cpp.

void CXmlExample::OnEndPrefixMappingL	(	const RString &	aPrefix,
		TInt	aErrorCode
	)

Notification of the end of the scope of a prefix-URI mapping.

Definition at line 319 of file xmlexample.cpp.

void CXmlExample::OnIgnorableWhiteSpaceL	(	const TDesC8 &	aBytes,
		TInt	aErrorCode
	)

A notification of ignorable whitespace in element content.

Definition at line 331 of file xmlexample.cpp.

void CXmlExample::OnSkippedEntityL	(	const RString &	aName,
		TInt	aErrorCode
	)

A notification of a skipped entity. If the parser encounters an external entity, it does not need to expand it - it can return the entity as aName for the client to deal with.

Implementation of the pure virtual function of MContentHandler.

Parameters:

	aName	Name of the skipped entity.
	aErrorCode	The error code. KErrNotSupported

Definition at line 347 of file xmlexample.cpp.

void CXmlExample::OnProcessingInstructionL	(	const TDesC8 &	aTarget8,
		const TDesC8 &	aData8,
		TInt	aErrorCode
	)

A receive notification of a processing instruction. It prints the target and data to the console.

Implementation of the pure virtual function of MContentHandler.

Parameters:

	aTarget	The processing instruction target.
	aData	The processing instruction data. If empty, none was supplied.
	aErrorCode	The error code. If aErrorCode is not KErrNone, the function leaves.
