All,
I have the following C# code (listed at the end of the message) which does
list all the image tags on a given page request. The problem is it does not
list image tags that are created on the client via external .js files, for
example if the following was in an external .js
document.writeln("<img src=\"images/136195-gk-shirt-away.jpg\" />");
I could load each js file but I think I am starting to bark up the wrong
tree with this approach. I cannot guarantee if the images have been written
by document.writeln or they have been added via the DOM or the many
otherways there are to do this.
Can anyone think of a better way.
public void TestWebRequest()
{
WebRequest req =
WebRequest.Create("http://localhost:2178/Image/Default.aspx";);
ServicePointManager.ServerCertificateValidationCallback +=
delegate(object sender, X509Certificate cert, X509Chain chain,
SslPolicyErrors error)
{
return true;
};
StreamReader sr = new
StreamReader(req.GetResponse().GetResponseStream());
StringBuilder sb = new StringBuilder();
string line = string.Empty;
while ((line = sr.ReadLine()) != null)
{
if (line.Length > 0)
sb.Append(line);
}
_site = sb.ToString();
Regex r = new Regex("<img[^>]+>");
MatchCollection mcl = r.Matches(_site);
foreach (Match m in mcl)
{
foreach (Group g in m.Groups)
{
Console.WriteLine(g.Value);
}
}
}

What about having some automated process run IE and request the pages
you want to test. Then parse through your IIS logs and look for 404's.
Kind of a round-about way to do it, but at least this way you leave the
HTML parsing and HTTP requests to IE.

Thanks Peter,
It is a long and complicated story but as simply as I can put it, we
have to ensure that a particular .jpg file is on a requested page. My
first thoughts were to use javascript to parse the DOM but we cannot
guarantee that the element was rendered by an external .js file.
That is the requirement put as simply as I can.
We want to automate this process. The Html that is coming back is not
XHTML compliant or I would consider using the XmlHTTPRequest object.
Can you think of a simpler way to achieve this than examining the
HttpResponse.
Thanks
Paul
