Normalize Space in HtmlAgilityPack

Here is the html snippet. How do I get normalize-space text ?

To search for the same fragment, but using Xpath //*[normalize-space()='Text1 Text2']

<div>
    <div>
        <a></a>
        <a></a>
        <div><a><span></span>Text2</a></div>
    </div>
        <div>Text2</div>
</div>

Using:

var htmlNodes = htmlDoc.DocumentNode.SelectNodes("*");

foreach (var node in htmlNodes)
{
   text += node.InnerText;
}

I get this string:

"\r\n                        \r\n                        \r\n                        \r\n                        \r\n                        Text1\r\n                    Text2"

Can I get a normal text ?

"Text1 Text2"
