NAME

6       AnyEvent::XMPP::Node - XML node tree helper for the parser.
7

SYNOPSIS

9          use AnyEvent::XMPP::Node;
10          ...
11

DESCRIPTION

13       This class represens a XML node. AnyEvent::XMPP should usually not
14       require messing with the parse tree, but sometimes it is neccessary.
15
16       If you experience any need for messing with these and feel
17       AnyEvent::XMPP should rather take care of it drop me a mail, feature
18       request or most preferably a patch!
19
20       Every AnyEvent::XMPP::Node has a namespace, attributes, text and child
21       nodes.
22
23       You can access these with the following methods:
24

METHODS

26       new ($ns, $el, $attrs, $parser)
27           Creates a new AnyEvent::XMPP::Node object with the node tag name
28           $el in the namespace URI $ns and the attributes $attrs. The $parser
29           must be the instance of "AnyEvent::XMPP::Parser" which generated
30           this node.
31
32       name
33           The tag name of this node.
34
35       namespace
36           Returns the namespace URI of this node.
37
38       eq ($namespace_or_alias, $name) or eq ($node)
39           Returns true whether the current element matches the tag name $name
40           in the namespaces pointed at by $namespace_or_alias.
41
42           You can either pass an alias that was defined in
43           AnyEvent::XMPP::Namespaces or pass an namespace URI in
44           $namespace_or_alias. If no alias with the name $namespace_or_alias
45           was found in AnyEvent::XMPP::Namespaces it will be interpreted as
46           namespace URI.
47
48           The first argument to eq can also be another AnyEvent::XMPP::Node
49           instance.
50
51       eq_ns ($namespace_or_alias) or eq_ns ($node)
52           This method return true if the namespace of this instance of
53           AnyEvent::XMPP::Node matches the namespace described by
54           $namespace_or_alias or the namespace of the $node which has to be
55           another AnyEvent::XMPP::Node instance.
56
57           See "eq" for the meaning of $namespace_or_alias.
58
59       attr ($name)
60           Returns the contents of the $name attribute.
61
62       add_node ($node)
63           Adds a sub-node to the current node.
64
65       nodes
66           Returns a list of sub nodes.
67
68       add_text ($string)
69           Adds character data to the current node.
70
71       text
72           Returns the text for this node.
73
74       find_all (@path)
75           This method does a recursive descent through the sub-nodes and
76           fetches all nodes that match the last element of @path.
77
78           The elements of @path consist of a array reference to an array with
79           two elements: the namespace key known by the $parser and the
80           tagname we search for.
81
82       write_on ($writer)
83           This writes the current node out to the AnyEvent::XMPP::Writer
84           object in $writer.
85
86       as_string ()
87           This method returns the original character representation of this
88           XML element (and it's children nodes). Please note that the string
89           is a unicode string, meaning: to get octets use:
90
91              my $octets = encode ('UTF-8', $node->as_string);
92
93           Now you can roll stunts like this:
94
95              my $libxml = XML::LibXML->new;
96              my $doc    = $libxml->parse_string (encode ('UTF-8', $node->as_string ()));
97
98           (You can use your favorite XML parser :)
99
100       append_raw ($string)
101           This method is called by the parser to store original strings of
102           this element.
103
104       to_sax_events ($handler)
105           This method takes anything that can receive SAX events.  See also
106           XML::GDOME::SAX::Builder or XML::Handler::BuildDOM or
107           XML::LibXML::SAX::Builder.
108
109           With this you can convert this node to any DOM level 2 structure
110           you want:
111
112              my $builder = XML::LibXML::SAX::Builder->new;
113              $node->to_sax_events ($builder);
114              my $dom = $builder->result;
115              print "Canonized: " . $dom->toStringC14N . "\n";
