instruction.</p>
<p>Processing instructions are used in XML to keep
processor-specific information in the text of the document.</p>
<p>The XML declaration that appears at the top of an XML document,
typically <tt><?xml version='1.0' encoding='UTF-8'?></tt>, 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.</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>.

<a href="qdomdocument.html">QDomDocument</a> documentation.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QDomProcessingInstruction" />QDomProcessingInstruction.__init__ (<i>self</i>)</h3><p>Constructs an empty processing instruction. Use <a href="qdomdocument.html#createProcessingInstruction">QDomDocument.createProcessingInstruction</a>()
to create a processing instruction with content.</p>
<h3 class="fn"><a name="QDomProcessingInstruction-2" />QDomProcessingInstruction.__init__ (<i>self</i>, <a href="qdomprocessinginstruction.html">QDomProcessingInstruction</a> <i>x</i>)</h3><p>Constructs a copy of <i>x</i>.</p>
<p>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 <a href="qdomnode.html#cloneNode">cloneNode</a>().</p>
<h3 class="fn"><a name="data" />QString QDomProcessingInstruction.data (<i>self</i>)</h3><p>Returns the content of this processing instruction.</p>
<p><b>See also</b> <a href="qdomprocessinginstruction.html#setData">setData</a>() and <a href="qdomprocessinginstruction.html#target">target</a>().</p>
<h3 class="fn"><a name="nodeType" /><a href="qdomnode.html#NodeType-enum">QDomNode.NodeType</a> QDomProcessingInstruction.nodeType (<i>self</i>)</h3><p>Returns <tt>ProcessingInstructionNode</tt>.</p>
<h3 class="fn"><a name="setData" />QDomProcessingInstruction.setData (<i>self</i>, QString <i>d</i>)</h3><p>Sets the data contained in the processing instruction to
<i>d</i>.</p>
<p><b>See also</b> <a href="qdomprocessinginstruction.html#data">data</a>().</p>
<h3 class="fn"><a name="target" />QString QDomProcessingInstruction.target (<i>self</i>)</h3><p>Returns the target of this processing instruction.</p>
