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.

Constructor Detail

### QDomProcessingInstruction

    public QDomProcessingInstruction()

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

### QDomProcessingInstruction

    public QDomProcessingInstruction(QDomProcessingInstruction 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()`.

Method Detail

### data

    public final java.lang.String data()

  Returns the content of this processing instruction.

See also:
  `setData()`, and `target()`.

### setData

    public final void setData(java.lang.String d)

  Sets the data contained in the processing instruction to `d`.

See also:
  `data()`.

### target

    public final java.lang.String target()

  Returns the target of this processing instruction.

See also:
  `data()`.

### clone

    public QDomProcessingInstruction clone()

  This method is reimplemented for internal reasons

  Overrides:
    `clone` in class `QDomNode`
