.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class represents parsers of various syntaxes that can deliver a
\&\s-1RDF\s0 model either as a RDF::Redland::Stream of RDF::Redland::Statement objects or
directly into an RDF::Redland::Model object.
.SH "CONSTRUCTORS"
.IX Header "CONSTRUCTORS"
.IP "new [\s-1NAME\s0 [\s-1MIME_TYPE\s0 [\s-1URI\s0]]]" 4
.IX Item "new [NAME [MIME_TYPE [URI]]]"
Create a new RDF::Redland::Parser object for a syntax parser named \fI\s-1NAME\s0\fR,
with \s-1MIME\s0 Type \fI\s-1MIME_TYPE\s0\fR and/or \s-1URI\s0 \fI\s-1URI\s0\fR.  Any field can be undef
or omitted; if all are omitted, a parser that provides \s-1MIME\s0 Type 
application/rdf+xml will be requested.
.SH "METHODS"
.IX Header "METHODS"
.IP "parse_as_stream \s-1SOURCE_URI BASE_URI\s0" 4
.IX Item "parse_as_stream SOURCE_URI BASE_URI"
Parse the syntax at the RDF::Redland::URI \fI\s-1SOURCE_URI\s0\fR with optional base
RDF::Redland::URI \fI\s-1BASE_URI\s0\fR.  If the base \s-1URI\s0 is given then the content is
parsed as if it was at the base \s-1URI\s0 rather than the source \s-1URI.\s0
.Sp
Returns an RDF::Redland::Stream of RDF::Redland::Statement objects or
undef on failure.
.IP "parse_into_model \s-1SOURCE_URI BASE_URI MODEL\s0 [\s-1HANDLER\s0]" 4
.IX Item "parse_into_model SOURCE_URI BASE_URI MODEL [HANDLER]"
Parse the syntax at the RDF::Redland::URI \fI\s-1SOURCE_URI\s0\fR with optional base
RDF::Redland::URI \fI\s-1BASE_URI\s0\fR into RDF::Redland::Model \fI\s-1MODEL\s0\fR.  If the base \s-1URI\s0 is
given then the content is parsed as if it was at the base \s-1URI\s0 rather
than the source \s-1URI.\s0
.Sp
If the optional \fI\s-1HANDLER\s0\fR is given, it is a reference to a sub with the signature
  sub handler($$$$$$$$$) {
    my($code, \f(CW$level\fR, \f(CW$facility\fR, \f(CW$message\fR, \f(CW$line\fR, \f(CW$column\fR, \f(CW$byte\fR, \f(CW$file\fR, \f(CW$uri\fR)=@_;
    ...
  }
that receives errors in parsing.
.IP "parse_string_as_stream \s-1STRING BASE_URI\s0" 4
.IX Item "parse_string_as_stream STRING BASE_URI"
Parse the syntax in \fI\s-1STRING\s0\fR with required base
RDF::Redland::URI \fI\s-1BASE_URI\s0\fR.
.Sp
Returns an RDF::Redland::Stream of RDF::Redland::Statement objects or
undef on failure.
.IP "parse_string_into_model \s-1STRING BASE_URI MODEL\s0 [\s-1HANDLER\s0]" 4
.IX Item "parse_string_into_model STRING BASE_URI MODEL [HANDLER]"
Parse the syntax in \fI\s-1STRING\s0\fR with required base
RDF::Redland::URI \fI\s-1BASE_URI\s0\fR into RDF::Redfland::Model \fI\s-1MODEL\s0\fR.
.Sp
If the optional \fI\s-1HANDLER\s0\fR is given, it is a reference to a sub with the signature
  sub handler($$$$$$$$$) {
    my($code, \f(CW$level\fR, \f(CW$facility\fR, \f(CW$message\fR, \f(CW$line\fR, \f(CW$column\fR, \f(CW$byte\fR, \f(CW$file\fR, \f(CW$uri\fR)=@_;
    ...
  }
that receives errors in parsing.
.IP "feature \s-1URI\s0 [\s-1VALUE\s0]" 4
.IX Item "feature URI [VALUE]"
Get/set a parser feature.  The feature is named via RDF::Redland::URI
\&\fI\s-1URI\s0\fR and the value is a RDF::Redland::Node.  If \fI\s-1VALUE\s0\fR is given,
the feature is set to that value, otherwise the current value is
returned.
.IP "namespaces_seen" 4
.IX Item "namespaces_seen"
Get the set of namespace declarations seen during parsing as a
hash of key:prefix string (may be ''), value: RDF::Redland::URI objects.
