29 This module implements an XML parser with a interface similar to
30 XML::Parser. Though not all callbacks are supported, you should be able
31 to use it in the same way you use XML::Parser. Due to using
32 experimental regexp features it'll work only on Perl 5.6 and above and
33 may behave differently on different platforms.
34
35 Note that you cannot use regular expressions or split in callbacks.
36 This is due to a limitation of perl's regular expression implementation
37 (which is not re-entrant).
38
40 new
41 Constructor.
42
43 The new() method returns the object called on when called as object
44 method. This behaviour was inherited from SOAP::Lite, which
45 XML::Parser::Lite was split out from. This means that the following
46 effectively is a no-op if $obj is a object:
47
48 $obj = $obj->new();
49
50 New accepts a single named parameter, "Handlers" with a hash ref as
51 value:
52
53 my $parser = XML::Parser::Lite->new(
54 Handlers => {
55 Start => sub { shift; print "start: @_\n" },
56 Char => sub { shift; print "char: @_\n" },
57 End => sub { shift; print "end: @_\n" },
58 }
59 );
60
61 The handlers given will be passed to setHandlers.
62
63 setHandlers
64 Sets (or resets) the parsing handlers. Accepts a hash with the handler
65 names and handler code references as parameters. Passing "undef"
66 instead of a code reference replaces the handler by a no-op.
67
68 The following handlers can be set:
69
70 Init
71 Start
72 Char
73 End
74 Final
75
76 All other handlers are ignored.
77
78 Calling setHandlers without parameters resets all handlers to no-ops.
79
80 parse
81 Parses the XML given. In contrast to XML::Parser's parse method,
82 parse() only parses strings.
83
85 Init
86 Called before parsing starts. You should perform any necessary
87 initializations in Init.
88
89 Start
90 Called at the start of each XML node. See XML::Parser for details.
91
92 Char
93 Called for each character sequence. May be called multiple times for
94 the characters contained in an XML node (even for every single
95 character). Your implementation has to make sure that it captures all
96 characters.
97
98 End
99 Called at the end of each XML node. See XML::Parser for details

104 XMLDecl
105 See XML::Parser for details
106
107 Doctype

109
110 Final
111 Called at the end of the parsing process. You should perform any
112 necessary cleanup here.

115 XML::Parser - a full-blown XML Parser, on which XML::Parser::Lite is
116 based. Requires a C compiler and the expat XML parser.
117
118 XML::Parser::LiteCopy - a fork in XML::Parser::Lite::Tree.
119
120 YAX - another pure-perl module for XML parsing.
121
122 XML::Parser::REX - another module that parses XML with regular
123 expressions.
