Duplicate content even if "unique target" is set

I have the same issue. Here is my feed:

<rss><channel>
    <title>Channel Title</title>
        <item><title>Item 1</title><guid>A</guid></item>
        <item><title>Item 2</title><guid>B</guid></item>
    </channel></rss>

Context is set to: //channel | //item and mapping settings are:

//item/title -> Node title
//item/guid -> GUID (unique)
//channel/title -> Text Field

I get two nodes created, but both have the title of "Array". I see from the debug code that this is the same issue as the original post.

xpathparser:0:
<title>Item 1</title>
<title>Item 2</title>
xpathparser:1:
<guid>A</guid>
<guid>B</guid>
xpathparser:2:
<title>Channel Title</title>
xpathparser:0:
<title>Item 1</title>
<title>Item 2</title>
xpathparser:1:
<guid>A</guid>
<guid>B</guid>
xpathparser:2:
<title>Channel Title</title>

The channel title is of course mapped correctly because there is only one. The item titles and guids are imported successfully if I set the context to //item and map: title -> node title, but then I lose the ability to also map the channel title.

Hmm, okay so I've fixed my problem. I use //item as the context which solves the Array problem, and then use ancestor::channel/title to grab the channel title.

So I'm unsure whether the initial error was due to my abuse of XPath or whether this is an underlying bug.

@pvhee,

Things have changed a bit since that guide. Things are simpler now, but not backwards compatible sadly.

<item>

context: //item
description: description
price: g:price
etc.

The result you are getting is because //link returns all of the links in the document. That indeed will make the save fail since it can only take one result. Hope that helps!

I think I had similar problem. In my case the solution was to delete old records from feeds_source table in Drupal database. I noticed that I used only 10 importers (in feeds_importer table) but had about 20 sources (in feeds_source table). It was the reason that some records were duplicated. Finally I left only one source for one importer and it started working fine.
