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 node 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);
Abosolute path trigger condition is recommended because a ``Name'' tage could appear in different places and stands for differe 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.AUTHORS
