Htmlヘッダ part を Removal
var lines = source. Split (new string[] {"\ r \ n"}, Stringsplitoptions.none). SkipWhile (S =>!s.startswith ("<"));
var html = lines. ToArray () [0];

           //xdocumentに processing
             using (var sgmlreader = new Sgmlreader {DocType = "HTML", casefolding = Casefolding.tolower})
            {
                 Sgmlreader.inputstream = new StringReader (HTML);
                var xml = Xdocument.load (Sgmlreader);

Item リンク Part を Take I did easily out し
var query =
From Ele in XML. Elements (). Descendants ()
where Ele. Attribute ("class")!= null && ele. Attribute ("Class"). Value = = "G"
Select Ele. Element ("H3");

リンクurl for Plastic
var regex = new Regex (@ "/url\?q= (. *) \&sa");

foreach (var item in query)
{
if (item!= NULL)
{
var mc = regex. Matches (item. Element ("a"). Attribute ("href"). Value);
if (MC. Count > 0)
{
var url = mc[0]. GROUPS[1]. Value;
Yield return new string[] {item. Element ("a"). Value, URL};
}
}
}
}
}
