An experiment... 
I've done some coding and implemented an in browser opml viewer.
This can represent an opml file in a page as a dynamic tree (it uses the standard OPML editor icons), moreover if the outline links to another opml file in the same domain it is able to asyncronously (in the background) load the linked outline and expand it in place. This feature works well across all the outline saved in hosting.opml.org!
technically it does this:
| | it loads and parses the opml file using the browsers' DOM parsers |
| | It traverses the opml dom object building a dhtml tree on the page which: |
| | uses the outline type / content to mark with the proper icon the text |
| | asyncronously (in the background) loads and includes the linked outlines |
Some examples:
It still has much to be refined (i consider it alpha quality), but feel free to use it as you like (if you find it interesting drop me a line at l.mearelli AT spazidigitali.com)
