when rendered it looks something like this:
here is the data that I wanted to parse out of there:
1/30/12 ZZ324sdf 51446 / 75 HOLD_DE 234234 smith, john PPPM-6P - SOME AGENCY 1/31/12 SFD3434 51668 / 17 HOLD_DE FOY, EL FOY, ALEX someagency & Associates LLC 1/31/12 SFD3434 51668 / 25 HOLD_DE JAMISON, PA JAMISON, ROY someagency & Associates LLC 1/31/12 SFD3434 51669 / 34 HOLD_DE NEWMAN, SO NEWMAN, ALEX someagency & Associates LLC
so far I have tried:
foreach (HtmlNode link in htmlSnippet.DocumentNode.SelectNodes("//a[@href]"))
{
HtmlAttribute att = link.Attributes["href"];
hrefTags.Add(att.Value);
}
but I understand this will extract only the AHREF, and I want to extract the table elements.
how do I do this? Thank you so much for your help.
Think of it slightly differently -- instead of wanting every anchor (with a href), You want every row from the body of the table with class style_15 (that id looks very generated on the fly); then, for every row, you'll want every cell.
foreach (var row in htmlSnippet.DocumentNode.SelectNodes("//table[@class = 'style_15']/tbody/tr"))
{
foreach (var cell in row.SelectNodes("td"))
{
// Do something
}
}
