Extraction/validation Rule Code

I don't think we are going to release the source for those rules but there are some samples on the web. But the code is all managed and not obfuscated so if you are resourceful you could probably figure out how they work.

See my answer in the following post http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=509966&SiteID=1

you can find some detailed information about creating a custom extraction rule on the following site http://blogs.msnd.com/joshch as far as parsing out your text goes:

Here is an expample of looking for a tag with a specific attribute. Then grabbing the value from one of the attributes and parsing it to get a specific part of te string. The tag in question will look like the following

<a id="Categories_repCategories_ctl01_lnkCategory" href="Products.aspx?page=0&amp;categoryId=BIRDS">Birds</a>

and the code to get the category id out of it looks like this:

public class ExtractRandomCategory : ExtractionRule { public override void Extract(object sender, ExtractionEventArgs e) { List linkTags = new List(); e.Success = false; if (e.Response.IsHtml) { foreach (HtmlTag tag in e.Response.HtmlDocument.GetFilteredHtmlTags( "a" )) { if (tag.GetAttributeValueAsString("id").StartsWith("Categories")) { linkTags.Add(tag); } } } Random rand = new Random(); int linkIndex = rand.Next(linkTags.Count); HtmlTag linkTag = linkTags[linkIndex]; string linkValue = linkTag.GetAttributeValueAsString("href"); string categoryId; string categoryIdParamName = "categoryId="; if (linkValue.IndexOf(categoryIdParamName) != -1) { categoryId = linkValue.Substring((linkValue.IndexOf(categoryIdParamName) + categoryIdParamName.Length)); e.WebTest.Context.Add(this.ContextParameterName, categoryId); e.Success = true; } else { e.Success = false; } return; } public override string RuleName { get { return "Extract Ramdom Category Id"; } } }
