This module allows you to extract data from any website when no RSS link is available.

For this purpose, an extractor code is created that will take the indicated data from the web site and insert it into an indicated scene element, updating its content periodically.

Name: Name to identify the extractor.

URL: complete address of the website, of the page from which the data will be extracted.

Data collection interval: Interval, in minutes, for updating the data.

Capture parameters: Contain the reference texts that will be used to locate the data. For example, if we want to retrieve the quote of a currency from a web site, we proceed:

  1. Load the website in question in a browser, and access the page containing the data. The URL of this page is the one to be copied into the URL field (it can be a sub-page of the root site).
  2. By accessing the HTML code of the site (in Google Chrome, right click → Inspect) search in the code for the data of interest (with the Search option of the browser). The data may appear in a code similar to the one in the example:

<div class="col-md-6 purchase">

<h4 class="pull-left">Buy <span class="pull-right">$71.66</span></h4>.

</div>

  1. In the field "Get data after" enter the text preceding the data, in the example: <h4 class="pull-left">Buy <span class="pull-right">Purchase <span class="pull-right">.
  2. In the "Get data up to" field enter the text that follows the data. In the example: </span></h4>.
  3. In the "First to find" field, a line can be placed to identify in the code the sector containing the data, in case the text surrounding the data is repeated in other sectors of the code. In the example: <div class="col-md-6 purchase">

Element to update: Displays a list of text type scene elements.

Update with text: Allows you to enter a text to beadded to the data obtained. The {D} statement in this field is replaced by the data. Following the previous example, the text could be: Dollar buy: {D}. The screen will show the legend Dollar buy $71.66
