55
56
57The QDomProcessingInstruction class represents an XML processing
58instruction.
59
60<p>
61
62<p> Processing instructions are used in XML to keep processor-specific
63information in the text of the document.
64<p> The content of the processing instruction is retrieved with <a href="#data">data</a>()
65and set with <a href="#setData">setData</a>(). The processing instruction's target is
66retrieved with <a href="#target">target</a>().
67<p> For further information about the Document Object Model see
68<a href="http://www.w3.org/TR/REC-DOM-Level-1/">http://www.w3.org/TR/REC-DOM-Level-1/</a> and

74<hr><h2>Member Function Documentation</h2>
75<h3 class=fn><a name="QDomProcessingInstruction"></a>QDomProcessingInstruction::QDomProcessingInstruction ()
76</h3>
77Constructs an empty processing instruction. Use
78<a href="qdomdocument.html#createProcessingInstruction">QDomDocument::createProcessingInstruction</a>() to create a processing
79instruction with content.
80
81<h3 class=fn><a name="QDomProcessingInstruction-2"></a>QDomProcessingInstruction::QDomProcessingInstruction ( const&nbsp;<a href="qdomprocessinginstruction.html">QDomProcessingInstruction</a>&nbsp;&amp;&nbsp;x )
82</h3>
83Constructs a copy of <em>x</em>.
84<p> The data of the copy is shared (shallow copy): modifying one node
85will also change the other. If you want to make a <a href="shclass.html#deep-copy">deep copy</a>, use
86<a href="qdomnode.html#cloneNode">cloneNode</a>().
87
88<h3 class=fn><a name="~QDomProcessingInstruction"></a>QDomProcessingInstruction::~QDomProcessingInstruction ()
89</h3>
90Destroys the object and frees its resources.
91
92<h3 class=fn><a href="qstring.html">QString</a> <a name="data"></a>QDomProcessingInstruction::data () const<tt> [virtual]</tt>
93</h3>
94Returns the content of this processing instruction.
95<p> <p>See also <a href="#setData">setData</a>() and <a href="#target">target</a>().
96
97<h3 class=fn>bool <a name="isProcessingInstruction"></a>QDomProcessingInstruction::isProcessingInstruction () const<tt> [virtual]</tt>
98</h3>
99Returns TRUE.
100
101<p>Reimplemented from <a href="qdomnode.html#isProcessingInstruction">QDomNode</a>.
102<h3 class=fn><a href="qdomnode.html#NodeType-enum">QDomNode::NodeType</a> <a name="nodeType"></a>QDomProcessingInstruction::nodeType () const<tt> [virtual]</tt>
103</h3>
104Returns <a href="qdomnode.html#NodeType-enum">ProcessingInstructionNode</a>.
105
106<p>Reimplemented from <a href="qdomnode.html#nodeType">QDomNode</a>.
107<h3 class=fn><a href="qdomprocessinginstruction.html">QDomProcessingInstruction</a>&nbsp;&amp; <a name="operator-eq"></a>QDomProcessingInstruction::operator= ( const&nbsp;<a href="qdomprocessinginstruction.html">QDomProcessingInstruction</a>&nbsp;&amp;&nbsp;x )
108</h3>
109Assigns <em>x</em> to this processing instruction.
110<p> The data of the copy is shared (shallow copy): modifying one node
111will also change the other. If you want to make a <a href="shclass.html#deep-copy">deep copy</a>, use
112<a href="qdomnode.html#cloneNode">cloneNode</a>().
113
114<h3 class=fn>void <a name="setData"></a>QDomProcessingInstruction::setData ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;d )<tt> [virtual]</tt>
115</h3>
116Sets the data contained in the processing instruction to <em>d</em>.
117<p> <p>See also <a href="#data">data</a>().
118
119<h3 class=fn><a href="qstring.html">QString</a> <a name="target"></a>QDomProcessingInstruction::target () const<tt> [virtual]</tt>
120</h3>
121Returns the target of this processing instruction.
122<p> <p>See also <a href="#data">data</a>().
