示例1: link
/**
* Easy access to <link> tags keyed by "rel" attributes.
*
* If $elt->link() is called with no arguments, we will attempt to
* return the value of the <link> tag(s) like all other
* method-syntax attribute access. If an argument is passed to
* link(), however, then we will return the "href" value of the
* first <link> tag that has a "rel" attribute matching $rel:
*
* $elt->link(): returns the value of the link tag.
* $elt->link('self'): returns the href from the first <link rel="self"> in the entry.
*
* @param string $rel The "rel" attribute to look for.
* @return mixed
