NAME

       POE::Filter::XML - XML parsing for the POE framework

VERSION

       version 1.102960

SYNOPSIS

        use POE::Filter::XML;
        my $filter = POE::Filter::XML->new();

        my $wheel = POE::Wheel:ReadWrite->new(
               Filter          => $filter,
               InputEvent      => 'input_event',
        );

DESCRIPTION

       POE::Filter::XML provides POE with a completely encapsulated XML parsing strategy for
       POE::Wheels that will be dealing with XML streams.

       The parser is XML::LibXML

CLASS_METHODS

   BUILDARGS
           (ClassName $class: @args) returns (HashRef)

       BUILDARGS is provided to continue parsing the old style ALL CAPS arguments. If any ALL
       CAPS argument is detected, it will warn very loudly about deprecated usage.

PUBLIC_ATTRIBUTES

   not_streaming
           is: ro, isa: Bool, default: false

       Setting the not_streaming attribute to true via new() will put this filter into non-
       streaming mode, meaning that whole documents are parsed before nodes are returned. This is
       handy for XMLRPC or other short documents.

PRIVATE_ATTRIBUTES

   buffer
           is: ro, isa: ArrayRef, traits: Array

       buffer holds the raw data to be parsed. Raw data should be split on network new lines
       before being added to the buffer. Access to this attribute is provided by the following
       methods:

           handles =>
           {
               has_buffer => 'count',
               all_buffer => 'elements',
               push_buffer => 'push',
               shift_buffer => 'shift',
               join_buffer => 'join',
           }

   callback
           is: ro, isa: CodeRef

       callback holds the CodeRef to be call in the event that there is an exception generated
       while parsing content. By default it holds a CodeRef that simply calls Carp::confess.

   handler
           is: ro, isa: POE::Filter::XML::Handler

       handler holds the SAX handler to be used for processing events from the parser.  By
       default POE::Filter::XML::Handler is instantiated and used.

       The "not_streaming" attribute is passed to the constructor of Handler.

   parser
           is: ro, isa: XML::LibXML

       parser holds an instance of the XML::LibXML parser. The "handler" attribute is passed to
       the constructor of XML::LibXML.

PUBLIC_METHODS

   get_one_start
           (ArrayRef $raw?)

       This method is part of the POE::Filter API. See "get_one_start" in POE::Filter for an
       explanation of its usage.

   get_one
           returns (ArrayRef)

       This method is part of the POE::Filter API. See "get_one" in POE::Filter for an
       explanation of its usage.

   put
           (ArrayRef $nodes) returns (ArrayRef)

       This method is part of the POE::Filter API. See "put" in POE::Filter for an explanation of
       its usage.

PROTECTED_METHODS

   reset
       reset() is an internal method that gets called when either a stream_start(1)
       POE::Filter::XML::Node gets placed into the filter via "put", or when a stream_end(1)
       POE::Filter::XML::Node is pulled out of the queue of finished Nodes via "get_one". This
       facilitates automagical behavior when using the Filter within the XMPP protocol that
       requires many new stream initiations.  This method is also called after every document
       when not in streaming mode.  Useful for handling XMLRPC processing.

       This method really should never be called outside of the Filter, but it is documented here
       in case the Filter is used outside of the POE context.

PRIVATE_METHODS

   BUILD
       A BUILD method is provided to parse the initial buffer (if any was included when
       constructing the filter).

NOTES

       This latest version got a major overhaul. Everything is Moose-ified using MooseX::Declare
       to provide more rigorous constraint checking, real accessors, and greatly simplified
       internals. It should be backwards compatible (even the constructor arguments). If not,
       please file a bug report with a test case.
