public class QDomProcessingInstruction
The QDomProcessingInstruction class represents an XML processing instruction. Processing instructions are used in XML to keep processor-specific information in the text of the document.
The XML declaration that appears at the top of an XML document, typically <?xml version='1.0' encoding='UTF-8'?>, is treated by QDom as a processing instruction. This is unfortunate, since the XML declaration is not a processing instruction; among other differences, it cannot be inserted into a document anywhere but on the first line.
Do not use this function to create an xml declaration, since although it has the same syntax as a processing instruction, it isn't, and might not be treated by QDom as such.
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 Level 1 and Level 2 Core. For a more general introduction of the DOM implementation see the QDomDocument
documentation.

public QDomProcessingInstruction()
QDomDocument::createProcessingInstruction()
to create a processing instruction with content.
public QDomProcessingInstruction(QDomProcessingInstruction 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()
.
