最近整理電腦東西,雖然WP7已成過去式,記錄下吧，代碼是該別人的,增加委托傳值,如得到獲取數(shù)據(jù)的百分比等

正則抓取下廚房數(shù)據(jù)

下廚房正則 <span\s+itemprop="amount"> (?<title>.+?)</span><img\b[^<>]*?\bsrc[\s\t\r\n]*=[\s\t\r\n]*[""']?[\s\t\r\n]*(?<imgUrl>[^\s\t\r\n""'<>]*)[^<>]*?/?[\s\t\r\n]*> 圖片<div\s+class="g-recipe-intro"\s+itemprop="summary">(?<title>.+?)</div> 介紹<em\s+itemprop="name">(?<title>.+?)</em> 配料<div\s+class="g-recipe-steps"\s+itemprop="instructions">.+?<ol>.+?<li>(?<title>.+?)<br\s+class="clr"/> 第一步 <li>(?<title>.+?)<br\s+class="clr"/>.+?</li> 做法 <pre\s+class="g-recipe-tips\s+g-f14">(?<title>.+?)</pre> 小貼士豆果<span><a\s+href="/store/lists/c1t(?<url>.+?)">(?<title>.+?)</a></span> 菜系類型 <a\s+href="(?<Href>.+?)"\s+target="_blank"><img.+?src="(?<ImgUrl>.+?)"\s+alt="(?<Name>.+?)"></a>.+?<p>(?<Place>.+?)</p> 菜系詳細(xì) <h2>特色菜：</h2>.+?([<span>.+?</span>].+?)</div> 特色菜 <dt>電話：</dt>.+?<dd>(?<Phone>.+?)</dd>做法 <em>(?<num>.+?)</em>.+?<span>(?<title>.+?)</span>.+? <img\s+src="(?<src>.+?)" <em>(?<num>.+?)</em>(?<title>.+?)<br\s+class="clr"/> No Image 主料 itemprop="name"\s+title=.+?的做法">(?<title>.+?)<span\s+class="buy-price"> <a\s+href=.+?的做法"\s+itemprop="name">(?<title>.+?)</a>

調(diào)用如果需要返回當(dāng)前狀態(tài)值,訂閱Event事件即可
