Detailed Description#
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 withsetData()
. The processing instruction’s target is retrieved withtarget()
.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.- __init__()#
Constructs an empty processing instruction. Use
createProcessingInstruction()
to create a processing instruction with content.- __init__(x)
- Parameters:
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()
.- data()#
- Return type:
str
Returns the content of this processing instruction.
- setData(d)#
- Parameters:
d – str
Sets the data contained in the processing instruction to
d
.See also
- target()#
- Return type:
str
Returns the target of this processing instruction.
