  • 0

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.

For example:

Sample Input:

<html>
   <head>
     <title>blah</title>
   </head>
   <body>
    <p>My content</p>
   </body>
</html>

Desired Output:

<p>My content</p>

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)

Can anyone point me in the right direction?

    I think you need to do it in pieces.

    you can do selectnodes of document for body or html as follows

    doc.DocumentNode.SelectSingleNode("//body") // returns body with entire contents :)

    then you can check for null values for criteria and if that is provided, you can take the string as it is.

    Hope it helps 🙂
