SuikaWiki::Markup::XML::Parser --- SuikaWiki: Simple XML parser

=head1 DESCRIPTION
|
| 7 |
|
|
|
| 8 |
|
|
This is a simple XML parser intended to be used with SuikaWiki::Markup::XML.
|
| 9 |
|
|
After parsing of the XML document, this module returns a SuikaWiki::Markup::XML
|
| 10 |
|
|
object so that you can handle XML document with that module (and other modules
|
| 11 |
|
|
implementing same interface).
|
| 12 |
|
|
|
| 13 |
|
|
This module is part of SuikaWiki.
