NAME
    XML::Node - Node-based XML parsing: a simplified interface to
    XML::Parser

SYNOPSIS
     use XML::Node;

     $xml_node = new XML::Node;
     $xml_node->register( $nodetype, $callback_type => \&callback_function );
     $xml_node->register( $nodetype, $callback_type => \$variable );

     open(FOO, 'xmlgenerator |');
     $p3->parse(*FOO);
     close(FOO);

     $xml_node->parsefile( $xml_filename );

DESCRIPTION
    If you are only interested in processing certain nodes in an XML file,
    this module can help you simplify your Perl scripts significantly.

    The XML::Node module allows you to register callback functions or
    variables for any XML node. If you register a call back function, it
    will be called when the nodes of the type you specified are encountered.
    If you register a variable, the content of a XML node will be appended
    to that variable automatically.

    Subroutine register accepts both absolute and relative node
    registrations.

    Here is an example of absolute path registration:

     1. register(">TestCase>Name", "start" => \&handle_TestCase_Name_start);

    Here are examples of single node name registration:

     2. register( "Name", "start" => \&handle_Name_start);
     3. register( "Name", "end"   => \&handle_Name_end);
     4. register( "Name", "char"  => \&handle_Name_char);

    Here is an example of attribute registration:

     5. register(">TestCase:Author", "attr" => \$testcase_author);

    Absolute path trigger condition is recommended because a "Name" tag
    could appear in different places and stands for different names.

    Example:

      1  <Testcase>
      2     <Name>Something</Name>
      3     <Oracle>
      4         <Name>Something</Name>
      5     </Oracle>
      6  </Testcase>

    Statement 1 causes &handle_TestCase_Name_start to be called when parsing
    Line 2. Statements 2,3,4 cause the three handler subroutines to be
    called when parsing both Line 2 and Line 4.

    This module uses XML::Parser.

EXAMPLE
    Examples "test.pl" and "parse_orders.pl" come with this perl module.

NOTE
    When you register a variable, XML::Node appends strings found to that
    variable. So please be sure to clear that variable before it is used
    again.
