How can I attach an element to the top of the Head element in HTML Agility Pack?

.net asp.net-mvc-2 c# html-agility-pack

Question

I'm trying to use HTML Agility Pack to append a script element into the top of the HEAD section of my html. The examples I have seen so far just use the AppendChild(element) method to accomplish this. I need the script that I am appending to the head section to come before some other scripts. How can I specify this?

Here's what I'm trying:

HtmlDocument htmlDocument = new HtmlDocument();
htmlDocument.Load(filePath);
HtmlNode head = htmlDocument.DocumentNode.SelectSingleNode("/html/head");
HtmlNode stateScript = htmlDocument.CreateElement("script");
head.AppendChild(stateScript);
stateScript.SetAttributeValue("id", "applicationState");
stateScript.InnerHtml = "'{\"uid\":\"testUser\"}'";

I would like a script tag to be added toward the top of HEAD rather than appended at the end.

Realizing that this is an old question, there is also the possibility of prepending child elements that might not have existed then.

// Load content as new Html document
HtmlDocument html = new HtmlDocument();
html.LoadHtml(oldContent);

// Wrapper acts as a root element
string newContent = "<div>" + someHtml + "</div>";

// Create new node from newcontent
HtmlNode newNode = HtmlNode.CreateNode(newContent);

// Get body node
HtmlNode body = html.DocumentNode.SelectSingleNode("//body");

// Add new node as first child of body
body.PrependChild(newNode);

// Get contents with new node
string contents = html.DocumentNode.InnerHtml;
