The TQXmlDeclHandler class provides an interface to report declaration
content of XML data.
< p >
< p > You can set the declaration handler with
< a href = "qxmlreader.html#setDeclHandler" > TQXmlReader::setDeclHandler< / a > ().
< p > This interface is based on the SAX2 extension DeclHandler.
< p > The interface provides < a href = "#attributeDecl" > attributeDecl< / a > (), < a href = "#internalEntityDecl" > internalEntityDecl< / a > () and
< a href = "#externalEntityDecl" > externalEntityDecl< / a > () functions.
< p > See also the < a href = "xml.html#sax2Intro" > Introduction to SAX2< / a > .
< p > < p > See also < a href = "qxmldtdhandler.html" > TQXmlDTDHandler< / a > , < a href = "qxmlcontenthandler.html" > TQXmlContentHandler< / a > , < a href = "qxmlentityresolver.html" > TQXmlEntityResolver< / a > , < a href = "qxmlerrorhandler.html" > TQXmlErrorHandler< / a > , < a href = "qxmllexicalhandler.html" > TQXmlLexicalHandler< / a > , and < a href = "xml-tools.html" > XML< / a > .

< p > The reader calls this function to report an attribute type
declaration. Only the effective (first) declaration for an
attribute is reported.
< p > The reader passes the name of the associated element in < em > eName< / em >
and the name of the attribute in < em > aName< / em > . It passes a string that
represents the attribute type in < em > type< / em > and a string that
represents the attribute default in < em > valueDefault< / em > . This string
is one of "#IMPLIED", "#REQUIRED", "#FIXED" or < a href = "ntqstring.html#TQString-null" > TQString::null< / a > (if
none of the others applies). The reader passes the attribute's
default value in < em > value< / em > . If no default value is specified in the
XML file, < em > value< / em > is TQString::null.
< p > If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function < a href = "#errorString" > errorString< / a > () to
get the error message.

< p > The reader calls this function to get an error string if any of
the handler functions returns FALSE.

< / h3 >
< p > The reader calls this function to report a parsed external entity
declaration. Only the effective (first) declaration for each
entity is reported.
< p > The reader passes the name of the entity in < em > name< / em > , the public
identifier in < em > publicId< / em > and the system identifier in < em > systemId< / em > . If there is no public identifier specified, it passes
< a href = "ntqstring.html#TQString-null" > TQString::null< / a > in < em > publicId< / em > .
< p > If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function < a href = "#errorString" > errorString< / a > () to
get the error message.

< p > The reader calls this function to report an internal entity
declaration. Only the effective (first) declaration is reported.
< p > The reader passes the name of the entity in < em > name< / em > and the value
of the entity in < em > value< / em > .
