/**
|
|
* This class is a monkey patch to 'extend' simplehtmldom to recognize <source>
|
|
* tags (HTML5) as self closing tag. This patch should be removed once
|
|
* simplehtmldom was fixed. This seems to be a issue with more tags:
|
|
* https://sourceforge.net/p/simplehtmldom/bugs/83/
|
|
*
|
|
* The tag itself is valid according to Mozilla:
|
|
*
|
|
* The HTML <picture> element serves as a container for zero or more <source>
|
|
* elements and one <img> element to provide versions of an image for different
|
|
* display device scenarios. The browser will consider each of the child <source>
|
|
* elements and select one corresponding to the best match found; if no matches
|
|
* are found among the <source> elements, the file specified by the <img>
|
|
* element's src attribute is selected. The selected image is then presented in
|
|
* the space occupied by the <img> element.
|
|
*
|
|
* -- https://developer.mozilla.org/en-US/docs/Web/HTML/Element/picture
|
|
*
|
|
* Notice: This class uses parts of the original simplehtmldom, adjusted to pass
|
|
* the guidelines of RSS-Bridge (formatting)
