Best way to trigger multiple Feeds importers?
I had almost the exact same need where I had to import data from xml files usinf HTTP fetcher. I had 5 importers and had to run one after the other.

I declared a function that triggered the importers programmatically one after the other.

For triggering each importer this is what I did -

$feeds_source = feeds_source($importer_id);
$feeds_config = $feeds_source-&gt;getConfigFor($feeds_source-&gt;importer-&gt;fetcher);
$feeds_config['source'] = $url;
$feeds_source-&gt;setConfigFor($feeds_source-&gt;importer-&gt;fetcher, $feeds_config);
$feeds_source-&gt;save();
$feeds_source-&gt;startImport();


where $importer_id is the machine name of the importer; you can find it in the table 'feeds_source' and $url is the url where you have your xml file. feeds_source()

And there's this awesome cron module - Elysia Cron which gives in its own words 'a fine grain control over each task and several ways to add custom cron jobs to your site'.

With Elysia's hook_cronapi() you can set up a cron job which calls your function at your set up intervals.

Though it seems really a long since your question.....I hope this is of some help.
