    Just a small update: escapeEcmaScrip() replaces escapeJavaScript() in 2015. 

    public static void main(String[] args) throws InterruptedException{ 
    driver = new FirefoxDriver();
    driver.get("http://dhtmlx.com/docs/products/dhtmlxTree/");
    replaceHTML(By.xpath("//*/span[text()='Supported browsers:']"), "<button type=\"button\"  onclick=\"alert('Hello World!!')\">Click Me!</button>");
}

 private static void replaceHTML(By by, String html) {
      WebElement e = driver.findElement(by);
     ((JavascriptExecutor) driver).executeScript("arguments[0].innerHTML='" + StringEscapeUtils.escapeEcmaScript(html) + "'", e);

}

    Using Java Selenium 2.4.2 I use the following to replace inner html of an existing element. I use the Apache StringEscapeUtils.escapeJavaScript to escape the HTML because this is a JavaScript replace of the inner html.

        public void replaceHTML(By by, String html) {
      WebElement e = driver.findElement(by);
      ((JavascriptExecutor) driver).executeScript("arguments[0].innerHTML='" + StringEscapeUtils.escapeJavaScript(html) + "'", e);
    }

    Example html String I passed in. 

    <button type="button" onclick="alert('Hello world!')">Click Me!</button>

    Notes:

    • I couldn't get "Lance Java's" approach to work because of invalid escaped characters. Adding a single quote after the equal sign fixed this problem.

    • I tested "Kenneth Baltrinic's" suggestion of using driver.get('about:blank'); but I wasn't able to write to the screen interacting with the base document. In java I had to use double quotes driver.get("about:blank"). I tested this with Chrome.

    If you don't want to create a file or load a URL before being able to replace the content of the page, you can always leverage the Data URLs feature, which supports HTML, CSS and JavaScript:

    ChromeDriver driver = new ChromeDriver();
html_content = """
<html>
     <head></head>
     <body>
         <div>
             Hello World =)
         </div>
     </body>
</html>
"""

driver.get("data:text/html;charset=utf-8," + html_content)

    You could load an empty page eg:

    <html></html>

    And then set it's innerHTML

    ChromeDriver driver = new ChromeDriver();
driver.get("file://empty-page.html");
String innerHtml = "<head>...</head><body onload="...">...</body>";
driver.executeScript("document.innerHTML = " + innerHtml);

    Then fire the load event on the body

    driver.executeScript("$(document.body).trigger('load');");

    Then get the resultant HTML

    String result = driver.executeScript("document.body.innerHTML;");

    You could fire up jetty embedded. The jetty instance could then serve in memory html strings as web pages via a Servlet / Handler.
