|
|---|
| 57 | The QDomImplementation class provides information about the
|
|---|
| 58 | features of the DOM implementation.
|
|---|
| 59 |
|
|---|
| 60 | <p>
|
|---|
| 61 |
|
|---|
| 62 | <p> This class describes the features that are supported by the DOM
|
|---|
| 63 | implementation. Currently the XML subset of DOM Level 1 and DOM
|
|---|
| 64 | Level 2 Core are supported.
|
|---|
| 65 | <p> Normally you will use the function <a href="qdomdocument.html#implementation">QDomDocument::implementation</a>()
|
|---|
| 66 | to get the implementation object.
|
|---|
| 67 | <p> You can create a new document type with <a href="#createDocumentType">createDocumentType</a>() and a
|
|---|
| 68 | new document with <a href="#createDocument">createDocument</a>().
|
|---|
| 69 | <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
|
|---|
| 70 | introduction of the DOM implementation see the <a href="qdomdocument.html">QDomDocument</a>
|
|---|
| 71 | documentation.
|
|---|
| 72 | <p> <p>See also <a href="#hasFeature">hasFeature</a>() and <a href="xml-tools.html">XML</a>.

|---|
| 75 | <h3 class=fn><a name="QDomImplementation"></a>QDomImplementation::QDomImplementation ()
|
|---|
| 76 | </h3>
|
|---|
| 77 | Constructs a QDomImplementation object.
|
|---|
| 78 |
|
|---|
| 79 | <h3 class=fn><a name="QDomImplementation-2"></a>QDomImplementation::QDomImplementation ( const <a href="qdomimplementation.html">QDomImplementation</a> & x )
|
|---|
| 80 | </h3>
|
|---|
| 81 | Constructs a copy of <em>x</em>.

| 82 |
|
|---|
| 83 | <h3 class=fn><a name="~QDomImplementation"></a>QDomImplementation::~QDomImplementation ()<tt> [virtual]</tt>
|
|---|
| 84 | </h3>
|
|---|
| 85 | Destroys the object and frees its resources.
|
|---|
| 86 |
|
|---|
| 87 | <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>
|
|---|
| 88 | </h3>
|
|---|
| 89 | Creates a DOM document with the document type <em>doctype</em>. This
|
|---|
| 90 | function also adds a root element node with the qualified name <em>qName</em> and the namespace URI <em>nsURI</em>.
|
|---|
| 91 |
|
|---|
| 92 | <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>
|
|---|
| 93 | </h3>
|
|---|
| 94 | Creates a document type node for the name <em>qName</em>.
|
|---|
| 95 | <p> <em>publicId</em> specifies the public identifier of the external
|
|---|
| 96 | subset. If you specify <a href="qstring.html#QString-null">QString::null</a> as the <em>publicId</em>, this
|
|---|
| 97 | means that the document type has no public identifier.
|
|---|
| 98 | <p> <em>systemId</em> specifies the system identifier of the external
|
|---|
| 99 | subset. If you specify QString::null as the <em>systemId</em>, this
|
|---|
| 100 | means that the document type has no system identifier.
|
|---|
| 101 | <p> Since you cannot have a public identifier without a system
|
|---|
| 102 | identifier, the public identifier is set to QString::null if there
|
|---|
| 103 | is no system identifier.
|
|---|
| 104 | <p> DOM level 2 does not support any other document type declaration
|
|---|
| 105 | features.
|
|---|
| 106 | <p> The only way you can use a document type that was created this
|
|---|
| 107 | way, is in combination with the <a href="#createDocument">createDocument</a>() function to
|
|---|
| 108 | create a <a href="qdomdocument.html">QDomDocument</a> with this document type.
|
|---|
| 109 | <p> <p>See also <a href="#createDocument">createDocument</a>().

|---|

|
|---|
| 112 | </h3>
|
|---|
| 113 | The function returns TRUE if QDom implements the requested <em>version</em> of a <em>feature</em>; otherwise returns FALSE.
