위키피디아에 정의된 Media RSS 란?
Media RSS (MRSS) is an RSS extension used for syndicating multimedia files (audio, video, image) in RSS feeds. It was designed in 2004 by Yahoo! and the Media RSS community, and adds several enhancements to RSS enclosures. One example of enhancements is specification of thumbnails for each media enclosure.
Media RSS is used by content publishers to feed media files into Yahoo! Video Search, which is a feature of Yahoo! Search that allows to search for video files. The format can be used for podcasting, which uses the RSS format as a means of delivering content to media-playing devices. Media RSS allows for a much more detailed description of the content to be delivered to the subscriber than is covered by the RSS standard.

아래 빨간 색인 부분에 가져 오고 싶은 element 명을 써 주면 됨....
내가 원하는 element는 "pubDate", "media:description", "media:title", 이고
media:thumbnail등과 같은 element는 attribute의 정보까지 읽어 오고자 했음~~
어쩌거 저쩌고 잘 쓰면 될것 같아요......ㅎㅎㅎ
