I am trying to parse a bit of data from an HTML file, but

  • 0

I am trying to parse a bit of data from an HTML file, but my Linq statement is not working. Here is the XML/HTML. Below, how can I extract the string “41.8;12.23” from the geo.position meta tag? Thx!!

Here is my Linq

   String longLat = (String)
        from el in xdoc.Descendants()
              where
               (string)el.Name.LocalName == "meta"
               & el.FirstAttribute.Name == "geo.position"
                select (String) el.LastAttribute.Value;

Here is my Xdocument

<span>
  <!--CTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt -->
  <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
      <meta content="application/xhtml+xml; charset=utf-8" http-equiv="Content-Type" />
      <meta content="text/css" http-equiv="Content-Style-Type" />
      <meta name="geo.position" content="41.8;12.23" />
      <meta name="geo.placename" content="RomeFiumicino, Italy" />
      <title>RomeFiumicino, Italy</title>
    </head>
    <body />
  </html>
</span>

Edit: My query as given returns nothing. The “inner” query seems to return a list of all the meta elements instead of just the one element I want.

Edit: The following Linq query works against the same XDocument to retreive a table with class name = “data”

    var dataTable =
        from el in xdoc.Descendants()
        where (string)el.Attribute("class") == "data"
        select el;

    A span around your html tag?

    You could do this with XLinq, but it would only support well-formed XML. You might want to look at the HTML Agility Pack instead.

    Edit – This works for me:

    string xml = "...";
var geoPosition = XElement.Parse(xml).Descendants().
    Where(e => e.Name.LocalName == "meta" &&
        e.Attribute("name") != null &&
        e.Attribute("name").Value == "geo.position").
    Select(e => e.Attribute("content").Value).
    SingleOrDefault();
