This experimental module is designed to allow for easy creation and manipulation of OPML files. OPML files are most commonly used for the sharing of blogrolls or subscriptions - an outlined list of what other blogs and Internet blogger reads. RSS Feed Readers such as AmphetaDesk (http://www.disobey.com/amphetadesk) use *.opml files to store your subscription information for easy access.
This is purely experimental at this point and has a few bugs and limitations. Most notably: the update feature seems to be wiping out previous outline items and only including the new ones.
Additionally, this module currently does not support embedded outlines (i.e., outline tags inside of outline tags). This is currently under development.
Rather than reinventing the wheel, this module was modified from the XML::RSS module, so functionality works in a similar way.
This is the constructor. It returns a reference to an XML::OPML object. This will always be version 1.1 for now, so don't worry about it.
This method with create all the OPML tags for the <head> subset. For more information on these tags, please see the OPML documentation at http://www.opml.org.
This method adds the <outline> elements to the OPML document(see the example above). There are no statement requirements for the attributes in this tag. The ones show in the example are the ones most commonly used by RSS Feed Readers, blogrolls, and subscriptions.
Returns a string containing the OPML document.
Saves the OPML document to $file
Uses XML::Parser to parse the value of the string that is passed to it.
Uses XML::Parser to parse the contents of $file.
