6 HTML::DOMbo -- convert between XML::DOM and {XML/HTML}::Element trees
7
9 use HTML::DOMbo;
10 use HTML::TreeBuilder;
11 my $tree = HTML::TreeBuilder->new;
12 $tree->parse_from_file('foo.html');
13 my $dom_tree = $tree->to_XML_DOM;
14 # Now you have a DOM element in $dom_tree!
15
17 This class puts a method into HTML::Element called "to_XML_DOM", and
18 puts into the class XML::DOM::Node two methods, "to_HTML_Element" and
19 "to_XML_Element".
20
21 to_XML_DOM
22 The class HTML::TreeBuilder robustly produces parse trees of HTML, but
23 the trees are made of HTML::Element objects, not W3C DOM objects. If
24 you want to access a TreeBuilder-made parse tree (in $tree) with a DOM
25 interface, use HTML::DOMbo and then call
26
27 my $dom_tree = $tree->to_XML_DOM;
28
29 This returns a new object of the appropriate class (presumably
30 XML::DOM::Element), in a new DOM document, having the same structure
31 and content as the given HTML::TreeBuilder/Element tree. If you want
32 the elements to be instantiated against an existing document object,
33 instead call:
34
35 my $dom_tree = $tree->to_XML_DOM($existing_dom_document);
36
37 to_HTML_Element and to_XML_Element
38 This module provides two experimental methods (in the XML::DOM::Node
39 class) called "to_HTML_Element" and "to_XML_Element", which clone a DOM
40 node (or DOM document, or document fragment) as a new HTML::Element or
41 XML::Element object. You need to have the XML::Element module (from
42 the XML::TreeBuilder dist) installed in order to use the
43 "to_XML_Element" method.
44
45 It is possible for this to throw a fatal exception. And it it possible
46 for this to return a text string instead (if the DOM node given was a
47 text node). Moreover, in list context it may return any number of
48 items, if the source object is a document fragment containing more than
49 one top-level node, or no nodes.
50
51 Users are encouraged to report to me any problems (or successes) in
52 using this method. The behavior of this method may change in response
53 to your requests.
