我试图从网站上获取图片。
HtmlWeb html = new HtmlWeb();
HtmlDocument htmldoc = html.Load("http://www.inc.com/christine-lagorio/fashion-week-wearable-technology.html");
var img = htmldoc.DocumentNode.SelectNodes("//*[@id='articleheaderimage']/img");
问题是img是空的，尽管它在HTML中。
所以我去检查图标签InnerHtml。
var figure = htmldoc.DocumentNode.SelectNodes("//figure");
似乎img标签转换为空格。
以下是一些InnerHtml
<div id="articleheaderimage" class="picture inc_editable inc_editable_image" data-editor-class="ImageEditor" data-label="Main Image" data-content-type="article" data-content-id="61627" data-fieldname="image" data-parent-id="wrappercontainer">
<!-- the image tag supposed to be here -->
<span class="smallest small-between-medium" data-src="http://www.inc.com/uploaded_files/image/640x290/wearable-technology_39857.jpg" data-src-x2="http://www.inc.com/uploaded_files/image/640x290/wearable-technology_39857.jpg"></span>
我需要做什么才能获得img标签？
