ttrss_plugin-af_feedmod

This is a plugin for Tiny Tiny RSS (tt-rss). It allows you to replace an article's contents by the contents of an element on the linked URL's page, i.e. create a "full feed".

Installation

Checkout the directory into your plugins folder like this (from tt-RSS root directory):

$ cd /var/www/ttrss
$ git clone git://github.com/mbirth/ttrss_plugin-af_feedmod.git plugins/af_feedmod

Then enable the plugin in preferences.

Configuration

The configuration is done in JSON format. In the preferences, you'll find a new tab called FeedMod. Use the large field to enter/modify the configuration data and click the Save button to store it. You can enter an URL in the field below and click Test to get a preview what the result will be if the filter is applied to the url.

A configuration looks like this:

{

"heise.de": {
    "type": "xpath",
    "xpath": "div[@class='meldung_wrapper']",
    "force_charset": "utf-8"
},
"berlin.de/polizei": {
    "type": "xpath",
    "xpath": "div[@class='bacontent']"
},
"n24.de": {
    "type": "xpath",
    "xpath": "div[@class='news']"
},
"golem0Bde0C": {
    "type": "xpath",
    "xpath": "article"
    "reformat": [
        {
            "type": "regex",
            "pattern": "/(?:[a-z0-9A-Z\\/.\\:]*?)golem0Bde0C(.*)0Erss0Bhtml\\/story01.htm/",
            "replace": "http://www.golem.de/$1.html"
        },
        {
            "type": "replace",
            "search": [
                "0A",
                "0C",
                "0B",
                "0E"
            ],
            "replace": [
                "0",
                "/",
                ".",
                "-"
            ]
        }
    ]
},
"oatmeal": {
    "type": "xpath",
    "xpath": "div[@id='comic']"
},
"blog.beetlebum.de": {
    "type": "xpath",
    "xpath": "div[@class='entry-content']",
    "cleanup": [ "header", "footer" ],
},
"www.spiegel.de": {
    "type": "split",
    "steps": [
        {
            "after": "/article-section clearfix\"\\W*>/",
            "before": "/<div\\W*class=\"module-box home-link-box/"
        },
        {
            "before": "/<div\\W*class=\"btwBarInArticles/"
        }
    ],
    "cleanup" : [ "~<script([^<]|<(?!/script))*</script>~msi" ],
    "force_unicode": true
}

}

The array key is part of the URL of the article links(!). You'll notice the golem0Bde0C in the last entry: That's because all their articles link to something like http://rss.feedsportal.com/c/33374/f/578068/p/1/s/3f6db44e/l/0L0Sgolem0Bde0Cnews0Cthis0Eis0Ean0Eexample0A10Erss0Bhtml/story01.htm and to have the plugin match that URL and not interfere with other feeds using feedsportal.com, I used the part golem0Bde0C.

type has to be xpath or split.

xpath

The xpath value is the actual Xpath-element to fetch from the linked page. Omit the leading // - they will get prepended automatically.

There is an additional option cleanup available. Its an array of Xpath-elements (relative to the fetched node) to remove from the fetched node. Omit the leading // - they will get prepended automatically.

split

The steps value is an array of actions performed in the given order. If after is given the content will be split using the value and the second half is used, if before the first half is used. preg_split is used for this action.

There is an additional option cleanup available. Its an array of regex that are removed using preg_replace.

General options

force_charset allows to override automatic charset detection. If it is omitted, the charset will be parsed from the HTTP headers or loadHTML() will decide on its own.

reformat is an array of formating rules for the url of the full article. The rules are applied before the full article is fetched. There are two possible types: regex and replace. regex takes a regex in an option called pattern and the replacement in replace. For details see preg_replace in the PHP documentation. replace uses the PHP function str_replace, which takes either a string or an array as search and replace value.

modify is the same as described above but for the content. It is applied after the split/xpath selection.

If you get an error about "Invalid JSON!", you can use JSONLint to locate the erroneous part.

XPath

Tools

To test your XPath expressions, you can use these Chrome extensions:

• XPath Helper
• xPath Viewer
• xpathOnClick

Examples

Some XPath expressions you could need (the // is automatically prepended and must be omitted in the FeedMod configuration):

HTML5 <article> tag

<article>…article…</article>

//article

DIV inside DIV

<div id="content"><div class="box_content">…article…</div></div>`

//div[@id='content']/div[@class='box_content']

Multiple classes

<div class="post-body entry-content xh-highlight">…article…</div>

//div[starts-with(@class ,'post-body')]

or

//div[contains(@class, 'entry-content')]
