<div id="reg-error-yid" class="oneid-error-message" data-error="messages.IDENTIFIER_EXISTS" role="alert">A Yahoo account already exists with this email address. <a href="https://login.yahoo.com/?intl=xa&amp;lang=en-JO&amp;src=ym&amp;.intl=xa&amp;specId=yidReg&amp;.done=https%3A%2F%2Fmail.yahoo.com&amp;nr=1&amp;step=2&amp;.crumb=qP.UnkGzfkR&amp;login=abtallaldigital">Sign in</a>.</div>

final HtmlPage page1 = webClient.getPage("https://login.yahoo.com/account/create?specId=yidReg&lang=en-JO&src=ym&done=https%3A%2F%2Fmail.yahoo.com&display=login&intl=xa");

             final DomElement firstName = page1.getElementById("usernamereg-firstName");
             final DomElement emailAddress = page1.getElementById("usernamereg-yid");
             final DomElement takenMsg = page1.getElementById("reg-error-yid");

I am not sure about your need. I can't comment here.

But if you are trying to parse the document you can use Jsoup for parsing the document.

The select is more useful and easy as compared to getElementById, byName, byXPath.

org.jsoup.nodes.Document doc = Jsoup.connect("https://login.yahoo.com/account/create?specId=yidReg&lang=en-JO&src=ym&done=https%3A%2F%2Fmail.yahoo.com&display=login&intl=xa").get();
org.jsoup.select.Elements takenMsgs = doc.select("div[id=reg-error-yid]");
org.jsoup.select.Element takenMsgFirst = doc.select("div[id=reg-error-yid]").first;

See if you can convert org.jsoup.select.Elements to com.gargoylesoftware.htmlunit.html.DomElement
