[NUnitAsp-devl] Change to handle multiple form tags

[Garrison, J. <JohnGa@DOR.WA.GOV>]

Our application has a non-asp.net form tag for the site search box.  The
code below for WebForm.cs allows NUnitASP to find the correct form tag.

		/// <summary>
		/// The HTML tag this tester corresponds to.
		/// </summary>
		protected HtmlTag Tag
		{
			get
			{
				XmlNodeList formNodes =
browser.CurrentPage.GetElementsByTagName("form");
				XmlElement formElement = null;
				if (formNodes.Count > 1)
				{
					for (int x = 0; x < formNodes.Count;
x++)
					{
						if
(formNodes[x].Attributes["id"].Value.StartsWith("_ctl"))
						{
							formElement =
(XmlElement)formNodes[x];
							break;
						}
					}
					Assertion.AssertNotNull("Multiple
<form> tags, none of which look like an ASPNET form.", formElement);
				}
				else
				{
					Assertion.AssertEquals("page form
elements", 1, formNodes.Count);
					formElement =
(XmlElement)formNodes[0];
				}
				XmlAttribute id =
formElement.Attributes["id"];
				Assertion.AssertNotNull("couldn't find web
form's 'id' attribute", id);

				return new HtmlTag(browser, id.Value, this);
			}
		}
