NAME

       XML::Element - XML elements with the same interface as HTML::Element

SYNOPSIS

	 [See HTML::Element]

METHODS AND ATTRIBUTES

   delete_ignorable_whitespace
       TODO: test and document this: with no tagname set, assumes ALL all-whitespace nodes are ignorable!

   endtag
       Redirects to HTML::Element::endtag_XML

   starttag
       Redirects to HTML::Element::starttag_XML

DESCRIPTION

       This is just a subclass of HTML::Element.  It works basically the same as HTML::Element, except that tagnames and attribute names aren't
       forced to lowercase, as they are in HTML::Element.

       HTML::Element describes everything you can do with this class.

CAVEATS

       Has currently no handling of namespaces.

       HTML::Element for all documentation.

       XML::DOM and XML::Twig for other XML document tree interfaces.

NAME

       XML::TreeBuilder - Parser that builds a tree of XML::Element objects

SYNOPSIS

	 foreach my $file_name (@ARGV) {
	   my $tree = XML::TreeBuilder->new({ 'NoExpand' => 0, 'ErrorContext' => 0 }); # empty tree
	   $tree->parse_file($file_name);
	   print "Hey, here's a dump of the parse tree of $file_name:
";
	   $tree->dump; # a method we inherit from XML::Element
	   print "And here it is, bizarrely rerendered as XML:
",
	     $tree->as_XML, "
";

	   # Now that we're done with it, we must destroy it.
	   $tree = $tree->delete;
	 }

DESCRIPTION

       This module uses XML::Parser to make XML document trees constructed of XML::Element objects (and XML::Element is a subclass of
       HTML::Element adapted for XML).	XML::TreeBuilder is meant particularly for people who are used to the HTML::TreeBuilder / HTML::Element
       interface to document trees, and who don't want to learn some other document interface like XML::Twig or XML::DOM.

       The way to use this class is to:

       1. start a new (empty) XML::TreeBuilder object.

       2. set any of the "store" options you want.

       3. then parse the document from a source by calling "$x->parsefile(...)"  or "$x->parse(...)" (See XML::Parser docs for the options that
       these two methods take)

       4. do whatever you need to do with the syntax tree, presumably involving traversing it looking for some bit of information in it,

       5. and finally, when you're done with the tree, call $tree->delete to erase the contents of the tree from memory.  This kind of thing
       usually isn't necessary with most Perl objects, but it's necessary for TreeBuilder objects.  See HTML::Element for a more verbose
       explanation of why this is the case.

METHODS AND ATTRIBUTES

       XML::TreeBuilder is a subclass of XML::Element, which in turn is a subclass of HTML:Element.  You should read and understand the
       documentation for those two modules.

       An XML::TreeBuilder object is just a special XML::Element object that allows you to call these additional methods:

       $root = XML::TreeBuilder->new()
	   Construct a new XML::TreeBuilder object.

	   Parameters:

	   NoExpand
		   Passed to XML::Parser. Do not Expand external entities.
		   Default: undef

	   ErrorContext
		   Passed to XML::Parser. Number of context lines to generate on errors.
		   Default: undef

       $root->eof
	   Deletes parser object.

       $root->parse(...options...)
	   Uses XML::Parser's "parse" method to parse XML from the source(s?)  specified by the options.  See XML::Parse

       $root->parsefile(...options...)
	   Uses XML::Parser's "parsefile" method to parse XML from the source(s?)  specified by the options.  See XML::Parse

       $root->parse_file(...options...)
	   Simply an alias for "parsefile".

       $root->store_comments(value)
	   This determines whether TreeBuilder will normally store comments found while parsing content into $root.  Currently, this is off by
	   default.

       $root->store_declarations(value)
	   This determines whether TreeBuilder will normally store markup declarations found while parsing content into $root.	Currently, this is
	   off by default.

       $root->store_pis(value)
	   This determines whether TreeBuilder will normally store processing instructions found while parsing content into $root.  Currently,
	   this is off (false) by default.
