25 | =head1 NAME |
---|
26 | |
---|
27 | XML::Stream::Tree - Functions to make building and parsing the tree easier |
---|
28 | to work with. |
---|
29 | |
---|
30 | =head1 SYNOPSIS |
---|
31 | |
---|
32 | Just a collection of functions that do not need to be in memory if you |
---|
33 | choose one of the other methods of data storage. |
---|
34 | |
---|
35 | =head1 FORMAT |
---|
36 | |
---|
37 | The result of parsing: |
---|
38 | |
---|
39 | <foo><head id="a">Hello <em>there</em></head><bar>Howdy<ref/></bar>do</foo> |
---|
40 | |
---|
41 | would be: |
---|
42 | Tag Content |
---|
43 | ================================================================== |
---|
44 | [foo, [{}, |
---|
45 | head, [{id => "a"}, |
---|
46 | 0, "Hello ", |
---|
47 | em, [{}, |
---|
48 | 0, "there" |
---|
49 | ] |
---|
50 | ], |
---|
51 | bar, [{}, |
---|
52 | 0, "Howdy", |
---|
53 | ref, [{}] |
---|
54 | ], |
---|
55 | 0, "do" |
---|
56 | ] |
---|
57 | ] |
