 この例では、 LinkNode(`links_root`)の xpath で指定された各リンク先のページから、TextNode(`text_title`,`text_content`) の xpath で指定された2つのテキストをスクレイピングする例です．
 
 (言い換えると、`//*[@id="menu"]/ul/li/a` で示される各リンクを開いて、`//*[@id="contents"]/h2` と `//*[@id="contents"]/p[1]` で指定されたテキストをスクレイピングします)

 This example, from the pages of each link that is expressed by the xpath of LinkNode(`links_root`), to scraping the two text that is expressed by the xpath of TextNode(`text_title`,`text_content`).
 
 (i.e. open each links `//*[@id="menu"]/ul/li/a` and, scrape `//*[@id="contents"]/h2` and `//*[@id="contents"]/p[1]`.)
