HTML敏捷性包 - 从HTML文档获取HTML片段 [英] Html Agility Pack - Get html fragment from an html document
问题描述
使用HTML敏捷包;我将如何提取完整的HTML文件的HTML片段?对于我而言,一个html片段被定义为<内部的所有内容;车身方式>
标签
Using the html agility pack; how would I extract an html "fragment" from a full html document? For my purposes, an html "fragment" is defined as all content inside of the <body>
tags.
例如:
输入示例:
<html>
<head>
<title>blah</title>
</head>
<body>
<p>My content</p>
</body>
</html>
所需的输出:
<p>My content</p>
在理想情况下,我想返回的内容不变,如果不包含< HTML>
或<身体GT;
元素(例如:假设我是通过一个片段摆在首位,如果它WASN。 'T完整的HTML文件)
Ideally, I'd like to return the content unaltered if it didn't contain an <html>
or <body>
element (eg. assume that I was passed a fragment in the first place if it wasn't a full html document)
任何人都可以点我在正确的方向?
Can anyone point me in the right direction?
推荐答案
我认为你需要做这捆柴。
I think you need to do it in pieces.
您可以做身体或HTML文件的selectNodes如下:
you can do selectnodes of document for body or html as follows
doc.DocumentNode.SelectSingleNode("//body") // returns body with entire contents :)
,那么你可以检查的标准空值,如果该提供,您可以根据它是以字符串。
then you can check for null values for criteria and if that is provided, you can take the string as it is.
希望它能帮助:)
