Linguistic Tree Constructor 3.0.0 (Default branch)
Image Linguistic Tree Constructor is an application for drawing linguistic syntax trees. "Generic" trees as well as RRG and X-Bar trees are supported, as is exporting to Annotation Graph XML format. Printing and copying parts of the tree to clipboard are supported. License: GNU General Public License (GPL) Changes:
The file format was changed from an ad-hoc solution to being based on the TIGER-XML standard. All tree operations are now substantially faster. The state of the interface is now saved in the document file. Export to Emdros MQL was improved. Image

xml::parser::lite::tree

XML::Parser::Lite::Tree(3pm)				User Contributed Perl Documentation			      XML::Parser::Lite::Tree(3pm)

NAME

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

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.
