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.</p> <p>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.</p> <p>The content of the processing instruction is retrieved with <a href="qdomprocessinginstruction.html#data">data</a>() and set with <a href="qdomprocessinginstruction.html#setData">setData</a>(). The processing instruction's target is retrieved with <a href="qdomprocessinginstruction.html#target">target</a>().</p> <p>For further information about the Document Object Model see <a href="http://www.w3.org/TR/REC-DOM-Level-1/">Level 1</a> and <a href="http://www.w3.org/TR/DOM-Level-2-Core/">Level 2 Core</a>.
