    PySide.QtXml.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 PySide.QtXml.QDomProcessingInstruction.data() and set with PySide.QtXml.QDomProcessingInstruction.setData() . The processing instruction's target is retrieved with PySide.QtXml.QDomProcessingInstruction.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 PySide.QtXml.QDomDocument 文档编制。

    class PySide.QtXml. QDomProcessingInstruction
    class PySide.QtXml. QDomProcessingInstruction ( x )
    参数: x PySide.QtXml.QDomProcessingInstruction

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

    构造副本为 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 PySide.QtXml.QDomNode.cloneNode() .

    PySide.QtXml.QDomProcessingInstruction. data ( )
    返回类型: unicode

    Returns the content of this processing instruction.

    PySide.QtXml.QDomProcessingInstruction. setData ( d )
    参数: d – unicode

    Sets the data contained in the processing instruction to d .

    PySide.QtXml.QDomProcessingInstruction. target ( )
    返回类型: unicode

    Returns the target of this processing instruction.
