How to remove the insignificant whitespace in a XmlNodeType.Text node?

Question

I have an html node:

<p>Line1
Line2
Line
ThereAreTwoSpacesAfterThis  ThereAreTwoSpacesBeforeThis
</p>

In any browser, the final use result is

Line1 Line2 Line ThereAreTwoSpacesAfterThis ThereAreTwoSpacesBeforeThis 

which is the result I want.

So how to remove the insignificant whitespace in a XmlNodeType.Text node (C#)?

Hi guys, Thanks for your reply.

Actually I'm working on a small project to extract all the text from a web page (html): something like "Save As page as text file" from Firefox or IE.

I tried to use Html Agility Pack, but the result is not good enough.

I also tried to use a WebBrowser control, but it seems too slow, and it's kind of not so easy to control over it.

Any good ideas?

I understand that guys suggest me to use regex, but there are too many cases to think about.

Just use a regular expression!

var spacesSquashed = Regex.Replace(input, @"\s+", " ", RegexOptions.Singleline);

If you also want to remove all spaces at the beginning and end, as is customary in HTML, add an extra .Trim() at the end.
