NAME

XML::Parser::Lite::Tree - Lightweight XML tree builder

CONTENTS

SYNOPSIS



  use XML::Parser::Lite::Tree;

  my $tree_parser = XML::Parser::Lite::Tree::instance();
  my $tree = $tree_parser->parse($xml_data);

    OR

  my $tree = XML::Parser::Lite::Tree::instance()->parse($xml_data);



DESCRIPTION

This is a singleton class for parsing XML into a tree structure. How does this differ from other XML tree generators? By using XML::Parser::Lite, which is a pure perl XML parser. Using this module you can tree-ify simple XML without having to compile any C.

For example, the following XML:



  <foo woo="yay"><bar a="b" c="d" />hoopla</foo>



Parses into the following tree:



          children => [
                          {
                            children => [
                                            {
                                              children => [],
                                              attributes => {
                                                                a => b,
                                                                c => d
                                                              },
                                              type => element,
                                              name => bar
                                            },
                                            {
                                              content => hoopla,
                                              type => text
                                            }
                                          ],
                            attributes => {
                                              woo => yay
                                            },
                            type => element,
                            name => foo
                          }
                        ],
          type => root
        };



Each node contains a type key, one of root, element and text. root is the document root, and only contains an array ref children. element represents a normal tag, and contains an array ref children, a hash ref attributes and a string name. text nodes contain only a content string.

METHODS

instance() Returns an instance of the tree parser.
new( options... ) Creates a new parser. Valid options include process_ns to process namespaces.
parse($xml) Parses the xml in $xml and returns the tree as a hash ref.
