Additional rows being added to db from xml feed

I was trying to decide which forum to place this question in, so if this is the wrong place then I apologise.

Basically, what’s happened is that I’m looking to take information from a merchant’s XML feed and place it in a database on my server.

That’s all happening fine, but when I look at the data in the database, I’m seeing that every other row is an empty row containing no data at all other than an auto Incrementing ID.

Is this likely to be a problem with the PHP script? Or with the feed itself?

Thanks very much for your help

I suppose it could be a few things. My best guess would be either the XML parsing or the db insert query, not the feed itself.
