Blauer Bote OPML-Reader enables you to import a local OPML file or OPML URL to read.
For this to work the OPML file has to have items that are RSS feeds, not just text or normal links.
When you submit, it returns the latest contents of all the feeds in the OPML file in separate display boxes, also displays the feed icon for easy subscribing.
If you import an OPML file that has just text or normal links choose “—” from the drop down menu instead of “rss”…although the results are shown in a running list only, not within an outline, otherwise try OPML search or OPMLsurfer.
