NAME

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

VERSION

       version 1.140700

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

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).
