For feeds that accept only a summary, it's possible to download the full content directly from the original website.
How the content grabber works?
- Try with rules first (xpath patterns) for the domain name (see
PicoFeed\Rules\) - Try to find the text content by using common attributes for class and id
- Fallback to Readability if no content is found
- Finally, if nothing is found, the feed content is displayed
The content downloader use a fake user agent, actually Google Chrome under Mac Os X.
However the content grabber doesn't work very well with all websites.
The best results are obtained with Xpath rules file.
How to write a grabber rules file?
Add a PHP file to the directory PicoFeed\Rules, the filename must be the domain name:
Example with the BBC website, www.bbc.co.uk.php:
<?php
return array(
'test_url' => 'http://www.bbc.co.uk/news/world-middle-east-23911833',
'body' => array(
'//div[@class="story-body"]',
),
'strip' => array(
'//script',
'//form',
'//style',
'//*[@class="story-date"]',
'//*[@class="story-header"]',
'//*[@class="story-related"]',
'//*[contains(@class, "byline")]',
'//*[contains(@class, "story-feature")]',
'//*[@id="video-carousel-container"]',
'//*[@id="also-related-links"]',
'//*[contains(@class, "share") or contains(@class, "hidden") or contains(@class, "hyper")]',
)
);
Actually, only body, strip and test_url are supported.
