Remember Feedster where you could enter an OPML URL in the search box, then enter a keyword in the other search box, isn’t this searching in an OPML URL.

I guess this OPML had to have just feeds as nodes, if it had an OPML include as a node I don’t think it would search in the OPML as well.

I recall perhaps FeedRinse lets you filter each feed in an OPML.

An OPML is only a list of feed names and feed URLs, so technically searching against an OPML wouldn’t make sense.

What you could do is to filter before splicing. It’s actually an approach that makes a LOT of sense, especially if you were going to filter that spliced feed to begin with. The big advantage I see is that you end up with a considerably larger, but still relevant spliced feed.

I don’t know of a tool that allows to filter the individual feeds in a remotely hosted OPML before they are spliced, but as I write this, I’m going to send in a feature request to the folks behind mySyndicaat and see what they say about the feasibility of this.

If you still want to pursue filtering before splicing right now, then you’d typically take each of the individual feeds, filter them, and eventually splice them. You’d be losing the dynamic nature of the original OPML file.

To what extent does this answer your question? P

Please feel free to ping me @cleverclogs on Twitter if I happen to fail to check this thread, ok?

As more people signed up for the event, their blogs were added to the OPML and then picked up by the Lijit search engine. Additionally, if you have a del.icio.us bookmark feed, as you add bookmarks those sites would be added.

What a question…exactly what I’m still asking…

I mentioned since OPML’s inception, can a public RSS Reader or search engine subscribe to my OPML, not bulk load it, but subscribe to it.

Sorry, but I can’t recall anything new, but search my blog, as I have posted lots and may have forgotten.

Marjolein from the CleverClogs blog could perhaps help us, I’ll send her a tweet.

Marjolein makes cool Grazr mashups where it will subscribe to an OPML, and she also puts in a search box. But I’m not sure if the search mashup is searching in a spliced feed or the OPML.

At the moment the only service I can think about is the BlogBridge RSS Reader, this can subscribe to an OPML, not sure if you can search in it, and plus it’s a personal/private RSS Reader.

What else, Lijit is more of a lifestream social filter search service, no go on that one, even though you can subscribe to another Lijit user…same goes with Spokeo
