.SH DESCRIPTION
The QXmlDeclHandler class provides an interface to report declaration content of XML data.
.PP
You can set the declaration handler with QXmlReader::setDeclHandler().
.PP
This interface is based on the SAX2 extension DeclHandler.
.PP
The interface provides attributeDecl(), internalEntityDecl() and externalEntityDecl() functions.
.PP
See also the Introduction to SAX2.
.PP
See also QXmlDTDHandler, QXmlContentHandler, QXmlEntityResolver, QXmlErrorHandler, QXmlLexicalHandler, and XML.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "bool QXmlDeclHandler::attributeDecl ( const QString & eName, const QString & aName, const QString & type, const QString & valueDefault, const QString & value )\fC [pure virtual]\fR"
The reader calls this function to report an attribute type declaration. Only the effective (first) declaration for an attribute is reported.
.PP
The reader passes the name of the associated element in \fIeName\fR and the name of the attribute in \fIaName\fR. It passes a string that represents the attribute type in \fItype\fR and a string that represents the attribute default in \fIvalueDefault\fR. This string is one of "#IMPLIED", "#REQUIRED", "#FIXED" or QString::null (if none of the others applies). The reader passes the attribute's default value in \fIvalue\fR. If no default value is specified in the XML file, \fIvalue\fR is QString::null.
.PP
If this function returns FALSE the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.
.SH "QString QXmlDeclHandler::errorString ()\fC [pure virtual]\fR"
The reader calls this function to get an error string if any of the handler functions returns FALSE.
.SH "bool QXmlDeclHandler::externalEntityDecl ( const QString & name, const QString & publicId, const QString & systemId )\fC [pure virtual]\fR"
The reader calls this function to report a parsed external entity declaration. Only the effective (first) declaration for each entity is reported.
.PP
The reader passes the name of the entity in \fIname\fR, the public identifier in \fIpublicId\fR and the system identifier in \fIsystemId\fR. If there is no public identifier specified, it passes QString::null in \fIpublicId\fR.
.PP
If this function returns FALSE the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.
.SH "bool QXmlDeclHandler::internalEntityDecl ( const QString & name, const QString & value )\fC [pure virtual]\fR"
The reader calls this function to report an internal entity declaration. Only the effective (first) declaration is reported.
.PP
The reader passes the name of the entity in \fIname\fR and the value of the entity in \fIvalue\fR.
.PP
If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function errorString() to
get the error message.
