.SH "NAME"
XML::LibXML::SAX \- XML::LibXML direct SAX parser
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
XML::LibXML provides an interface to libxml2 direct \s-1SAX\s0 interface. Through this
interface it is possible to generate \s-1SAX\s0 events directly while parsing a
document. While using the \s-1SAX\s0 parser XML::LibXML will not create a \s-1DOM\s0 Document
tree.
.PP
Such an interface is useful if very large \s-1XML\s0 documents have to be processed
and no \s-1DOM\s0 functions are required. By using this interface it is possible to
read data stored within an \s-1XML\s0 document directly into the application data
structures without loading the document into memory.
.PP
The \s-1SAX\s0 interface of XML::LibXML is based on the famous \s-1XML::SAX\s0 interface. It
uses the generic interface as provided by XML::SAX::Base.
.PP
Additionally to the generic functions, which are only able to process entire
documents, XML::LibXML::SAX provides \fI\f(BIparse_chunk()\fI\fR. This method generates \s-1SAX\s0 events from well balanced data such as is often
provided by databases.
.SH "FEATURES"
.IX Header "FEATURES"
\&\fI\s-1NOTE:\s0\fR This feature is experimental.
.PP
You can enable character data joining which may yield a significant speed boost
in your \s-1XML\s0 processing in lower markup ratio situations by enabling the
http://xmlns.perl.org/sax/join\-character\-data feature of this parser. This is
done via the set_feature method like this:
.PP
.Vb 1
\&  $p\->set_feature(\*(Aqhttp://xmlns.perl.org/sax/join\-character\-data\*(Aq, 1);
.Ve
.PP
You can also specify a 0 to disable. The default is to have this feature
disabled.
