showFullTitle4Googleですが

var xpath = './/h3/a|.//a[@class="_Dk"]|.//a[@class="_sQb"]|.//a[@class="gs-title"]|self::*[@class="irc_pt"]';
↓
var xpath = './/h3/a|.//a[@class="_Dk"]|.//a[@class="_sQb"]|.//a[@class="gs-title"]|self::*[contains(@class, "irc_pt")]|.//h3[./parent::a]';

にすれば多分動きます
あとでちゃんと直します
