Menu
I have a HTML document that contains lots of needless blank lines which I'd like to remove. Here's a sample of the HTML:
<html>
<head>
</head>
<body>
<h1>Heading</h1>
<p>Testing
I've tried the following code but it removed every newline, I just want to remove the ones that are blank lines.
static string RemoveLineReturns(string html)
{
html = html.Replace(Environment.NewLine, "");
return html;
}
Any idea how to do this with HTMLAgilityPack? Thanks, J.

One possible way using Html Agility Pack :
var doc = new HtmlDocument();
//TODO: load your HtmlDocument here
//select all empty (containing white-space(s) only) text nodes :
var xpath = "//text()[not(normalize-space())]";
var emptyNodes = doc.DocumentNode.SelectNodes(xpath);
//replace each and all empty text nodes with single new-line text node
foreach (HtmlNode emptyNode in emptyNodes)
{
emptyNode.ParentNode
.ReplaceChild(HtmlTextNode.CreateNode(Environment.NewLine)
, emptyNode
);
}
