<hr><a name="details"></a><h2>Detailed Description</h2>
The QDomImplementation class provides information about the
features of the DOM implementation.
<p>
<p> This class describes the features that are supported by the DOM
implementation. Currently the XML subset of DOM Level 1 and DOM
Level 2 Core are supported.
<p> Normally you will use the function <a href="qdomdocument.html#implementation">QDomDocument::implementation</a>()
to get the implementation object.
<p> You can create a new document type with <a href="#createDocumentType">createDocumentType</a>() and a
new document with <a href="#createDocument">createDocument</a>().
<p> For further information about the Document Object Model see <a href="http://www.w3.org/TR/REC-DOM-Level-1/">http://www.w3.org/TR/REC-DOM-Level-1/</a> and <a href="http://www.w3.org/TR/DOM-Level-2-Core/">http://www.w3.org/TR/DOM-Level-2-Core/</a>. For a more general
introduction of the DOM implementation see the <a href="qdomdocument.html">QDomDocument</a>
documentation.
<p> <p>See also <a href="#hasFeature">hasFeature</a>() and <a href="xml-tools.html">XML</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QDomImplementation"></a>QDomImplementation::QDomImplementation ()
</h3>
Constructs a QDomImplementation object.
<h3 class=fn><a name="QDomImplementation-2"></a>QDomImplementation::QDomImplementation ( const <a href="qdomimplementation.html">QDomImplementation</a> & x )
</h3>
Constructs a copy of <em>x</em>.
<h3 class=fn><a name="~QDomImplementation"></a>QDomImplementation::~QDomImplementation ()<tt> [virtual]</tt>
</h3>
Destroys the object and frees its resources.
<h3 class=fn><a href="qdomdocument.html">QDomDocument</a> <a name="createDocument"></a>QDomImplementation::createDocument ( const <a href="qstring.html">QString</a> & nsURI, const <a href="qstring.html">QString</a> & qName, const <a href="qdomdocumenttype.html">QDomDocumentType</a> & doctype )<tt> [virtual]</tt>
</h3>
Creates a DOM document with the document type <em>doctype</em>. This
function also adds a root element node with the qualified name <em>qName</em> and the namespace URI <em>nsURI</em>.
<h3 class=fn><a href="qdomdocumenttype.html">QDomDocumentType</a> <a name="createDocumentType"></a>QDomImplementation::createDocumentType ( const <a href="qstring.html">QString</a> & qName, const <a href="qstring.html">QString</a> & publicId, const <a href="qstring.html">QString</a> & systemId )<tt> [virtual]</tt>
</h3>
Creates a document type node for the name <em>qName</em>.
<p> <em>publicId</em> specifies the public identifier of the external
subset. If you specify <a href="qstring.html#QString-null">QString::null</a> as the <em>publicId</em>, this
means that the document type has no public identifier.
<p> <em>systemId</em> specifies the system identifier of the external
subset. If you specify QString::null as the <em>systemId</em>, this
means that the document type has no system identifier.
<p> Since you cannot have a public identifier without a system
identifier, the public identifier is set to QString::null if there
is no system identifier.
<p> DOM level 2 does not support any other document type declaration
features.
<p> The only way you can use a document type that was created this
way, is in combination with the <a href="#createDocument">createDocument</a>() function to
create a <a href="qdomdocument.html">QDomDocument</a> with this document type.
<p> <p>See also <a href="#createDocument">createDocument</a>().
<h3 class=fn>bool <a name="hasFeature"></a>QDomImplementation::hasFeature ( const <a href="qstring.html">QString</a> & feature, const <a href="qstring.html">QString</a> & version )<tt> [virtual]</tt>
</h3>
The function returns TRUE if QDom implements the requested <em>version</em> of a <em>feature</em>; otherwise returns FALSE.
<p> The currently supported features and their versions:

<tr bgcolor="#a2c511"> <th valign="top">Feature <th valign="top">Version
<tr bgcolor="#f0f0f0"> <td valign="top">XML <td valign="top">1.0
</table></center>
<h3 class=fn>bool <a name="isNull"></a>QDomImplementation::isNull ()
</h3>
Returns FALSE if the object was created by
<a href="qdomdocument.html#implementation">QDomDocument::implementation</a>(); otherwise returns TRUE.
<h3 class=fn>bool <a name="operator!-eq"></a>QDomImplementation::operator!= ( const <a href="qdomimplementation.html">QDomImplementation</a> & x ) const
</h3>
Returns TRUE if <em>x</em> and this DOM implementation object were
created from different QDomDocuments; otherwise returns FALSE.
<h3 class=fn><a href="qdomimplementation.html">QDomImplementation</a> & <a name="operator-eq"></a>QDomImplementation::operator= ( const <a href="qdomimplementation.html">QDomImplementation</a> & x )
</h3>
Assigns <em>x</em> to this DOM implementation.
<h3 class=fn>bool <a name="operator-eq-eq"></a>QDomImplementation::operator== ( const <a href="qdomimplementation.html">QDomImplementation</a> & x ) const
</h3>
Returns TRUE if <em>x</em> and this DOM implementation object were
created from the same <a href="qdomdocument.html">QDomDocument</a>; otherwise returns FALSE.
