Example #1
Import and sync RSS Feeds

17. Feeds importers are configurations of
Fetcher Parser Processor

21. create nodes of type Feed item

22. fields in RSS fields in Feed item

23. And now... importing!

24. /import

26. We can do this with Drupal Core Aggregator too!

27. Let’s try spawning
Feed A
User 1 Feed B
Feed A
User Feed B Feed C
Feed C
1
User 2 Feed X
Aggregator (core) Feeds

28. Spawning

29. Add Feed = Add Node

30. Example #2
Import images

31. A node of type Story will hold a Flickr image

32. the Flickr XML feed
{ http://www.flickr.com/services/feeds/geo?format=rss_200&tags=drupalcamp

33. Parse XML with XPath expressions
//item
title
link
description
geo:lat
geo:long
media:thumbnail/@url

34. Fetcher http
Parser XPath Parser
Map targets from XPath
Processor Node processor

35. select XPath XML parser

36. source is XPath Result fields in Story

39. Importing

41. We have problems
!
Tags are not imported correctly

42. Feeds Tamper
http://drupal.org/project/feeds_tamper

43. Enter Tampering
Input Field Output Field
explode
drupal feeds sevilla drupal
feeds
sevilla
html_encode
Me&lt;/a&gt;posted a <a href=”.”>Me</a>
photo:&lt;/p&gt; posted a photo

44. Configure Tampering

45. More tamper actions

46. Add your own tamper plugins
snippet from html_entity_decode.inc

47. After importing... tags are now
correctly split

48. Importing Big Stuff
‣ Feeds has Batch support
‣ Feeds can run on cron jobs in the
background

49. Field support
‣ Text ‣ Email
‣ File ‣ Multimedia
‣ Image ‣ Address
‣ Link
‣ Geofield
‣ Taxonomy Tip: check Feeds issue
‣ Password queues for patches
‣ Date
‣ Integer

50. Feeds as a Framework
‣ Supports import/sync of Commerce
Products (via Commerce Feeds)
‣ Straightforward to add custom fetchers,
patchers and processors using Feed
hooks (check feeds.api.php)

51. Finally...
when not to use Feeds
‣ Content does not need to be stored by
Drupal
‣ Complex content migration tasks

52. Now... Real-Time?

53. Enter PubSubHubBub
Publisher Hub Subscriber
What does this solve?
1. Notifications to Subscribers managed by Hub
2. Send only what is changed and when it gets
changed

54. Euhm.. so what does
Feeds do exactly?
Feeds makes Drupal a PSHB
Subscriber
Update feeds in real-time from PSHB Hubs
e.g. Blogger, Wordpress, Superfeedr, ...

55. Thanks!
