Detailed Description

The QDomProcessingInstruction class represents an XML processing instruction.

Processing instructions are used in XML as a way to keep processor-specific information in the text of the document.

The content of the processing instruction is retrieved with data() and set with setData(). The processing instruction's target is retrieved with target().

For further information about the Document Object Model see http://www.w3.org/TR/REC-DOM-Level-1/ and http://www.w3.org/TR/DOM-Level-2-Core/. For a more general introduction of the DOM implementation see the QDomDocument documentation.

Member Function Documentation

QDomProcessingInstruction::QDomProcessingInstruction ()

Constructs an empty processing instruction. Use QDomDocument::createProcessingInstruction() to create a processing instruction with content.

QDomProcessingInstruction::QDomProcessingInstruction ( constQDomProcessingInstruction&x )

Constructs a copy of x.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

QDomProcessingInstruction::~QDomProcessingInstruction ()

Destroys the object and frees its resources.

QString QDomProcessingInstruction::data () const [virtual]

Returns the content of this processing instruction.

See also setData() and target().

bool QDomProcessingInstruction::isProcessingInstruction () const [virtual]

Returns TRUE.

Reimplemented from QDomNode.

QDomNode::NodeType QDomProcessingInstruction::nodeType () const [virtual]

Returns ProcessingInstructionNode.

Reimplemented from QDomNode.

QDomProcessingInstruction& QDomProcessingInstruction::operator= ( constQDomProcessingInstruction&x )

Assigns x to this processing instruction.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

void QDomProcessingInstruction::setData ( constQString&d ) [virtual]

Sets the data contained in the processing instruction to d.

See also data().

QString QDomProcessingInstruction::target () const [virtual]

Returns the target of this processing instruction.

See also data().
