    Razor check whether item is empty or not in xml

    How do I make a check whether xml is empty or not

    --- XML if not empty ---

            <linkBox>

              <widgets>

                <widget isCollapsed="false">

                  <linkstype>interntlink</linkstype>

                  <boxlinktekst>test af internt link</boxlinktekst>

                  <eksternelinks />

                  <interntlink>

                    <contentPicker>

                      <content>1320</content>

                    </contentPicker>

                  </interntlink>

                </widget>

                <widget isCollapsed="false">

                  <linkstype>eksternelinks</linkstype>

                  <boxlinktekst>test af eksterne link</boxlinktekst>

                  <eksternelinks>http://www.onkelb.dk</eksternelinks>;

                  <interntlink>

                    <contentPicker />

                  </interntlink>

                </widget>

              </widgets>

            </linkBox>

     

    --- If empty -----

            <linkBox>

              <widgets>

                <widget isCollapsed="false">

                  <linkstype />

                  <boxlinktekst />

                  <eksternelinks />

                  <interntlink>

                    <contentPicker />

                  </interntlink>

                </widget>

              </widgets>

            </linkBox>

    Hi Brian, something like this perhaps? Do you need help reading the RSS feed in general or just checking for the value?

    @if(@node.Attributes["linkstype"].InnerText.ToString() == null)
    {
    do stuff
    }

    XElement root1 = XElement.Parse(
    @"<linkBox>
        <widgets>
          <widget isCollapsed='false'>
            <linkstype />
            <boxlinktekst />

    var links1 = from x in root1.Elements("widgets").Elements("widget")
                 where x.Element("eksternelinks").Value != "" || x.Element("interntlink").Element("contentPicker").Descendants("content").Count() > 0
    
                 select x;
    
    
    XElement root2 = XElement.Parse(
      @"<linkBox>
          <widgets>
            <widget isCollapsed='false'>
              <linkstype>interntlink</linkstype>
              <boxlinktekst>test af internt link</boxlinktekst>
              <eksternelinks />
              <interntlink>
                <contentPicker>
                  <content>1320</content>
                </contentPicker>
              </interntlink>
            </widget>
            <widget isCollapsed='false'>
              <linkstype>eksternelinks</linkstype>
              <boxlinktekst>test af eksterne link</boxlinktekst>
              <eksternelinks>http://www.onkelb.dk</eksternelinks>;
              <interntlink>
                <contentPicker />
              </interntlink>
            </widget>
          </widgets>
        </linkBox>");
    
    var links2 = from x in root2.Elements("widgets").Elements("widget")
                 where x.Element("eksternelinks").Value != "" || x.Element("interntlink").Element("contentPicker").Descendants("content").Count() > 0
    
                 select x;
    

    links1 should return empty

    links2 should return 2 items
