vbscript manipulation help -

I have a small snippet that captures the html of an external url, and stores it in "xmlhttp.responseText"

I want to be able to pick out a section based on one other variable, "isknown", which is a url that would be in an href="" attribute of the <A> tag.

Basically, I want to say:

if the url "known" exists in the html anywhere then

move forward in the code until the unknown anchor text is found, and capture that, and store as a variable.

else

send error

end if

I think I can use inStr() to find if the url exists,but not sure wehre i can go from there.

 

I suppose you are writing a crawler sort of thing. Your best bet is to use regular expressions and iterate until you have no more matches.

dim HtmlLinks as String = @"<a[^>]*?href\s*=\s*[""']?"; ' modify this regular expression to suit your needs

C#
MatchCollection mc = Regex.Matches(xmlhttp.responseText.ToString(), HtmlLinks);
foreach (Match mm in mc)
{
// what you want to do here
}

Although i've written it in C#, you should be able to easily convert in to VBScript after you've read about Regular Expressions.

 

okay so ive got the regexp down now, but having trouble implemnting...see thread:
