Question
I tried the suggestion from this forum before posting:
Remove gaps between markups in HTML source using C#?
A sample of the HTML I'm using is shown below:
<p>This is my text</p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p>This is next text</p>
HTML Agility Pack is what I'm using to tidy up the HTML:
HtmlDocument doc = new HtmlDocument();
doc.Load(htmlLocation);
foreach (var item in doc.DocumentNode.Descendants("p").ToList())
{
if (item.InnerHtml == " ")
{
item.Remove();
}
}
The code's result from above is
<p>This is my text</p>
<p>This is next text</p>
Therefore, my issue is with removing the unnecessary whitespace in the HTML code between the two paragraphs.

Between the first and final paragraphs, remove all text nodes:
HTML:
var html = @"
<p>This is my text</p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p>This is next text</p>";
Analyze it:
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
var paragraphs = doc.DocumentNode.Descendants("p").ToList();
foreach (var item in paragraphs)
{
if (item.InnerHtml == " ") item.Remove();
}
var followingText = paragraphs[0]
.SelectNodes(".//following-sibling::text()")
.ToList();
foreach (var text in followingText)
{
text.Remove();
}
Result:
<p>This is my text</p><p>This is next text</p>
Use a to maintain the line break between the paragraphs.for
call and loopRemove()
on each and every text node with the except code.
for (int i = 0; i < followingText.Count - 1; ++i)
{
followingText[i].Remove();
}
Result:
<p>This is my text</p>
<p>This is next text</p>
