I have created a Feed Importer and used XPath Parser for mapping. I have problem with updating a existing content. For example I have this xml structure.
<node> <nid>1</nid> <title>Title 1</title> </node> <node> <nid>2</nid> <title>Title 2</title> </node>
I started importer and everything is OK. I set NID as unique and check "Update existing content" in Node Process settings. So when I run importer again whit the same data this nodes have updated again.
Why have been updated ? The source is the same and don't any difference. Should It display, there is no new content to add if I start importer again and again with the same data ?
