LINQ | Paul Galvin's SharePoint Space

Evo primjer brzo koristeći LINQ tumačenje nekih XML i dobiti na slatko, slatki atributi u njoj.

Evo XML želim analizirati:

<?xml version = "1,0" kodiranja = "utf-8" ?>
<DeafultConfigurationSets>
<PageLayouts>

    <PageLayout name = "xyzzy">
      <Kartice>
        <Tab TabOrder="1" TabLabel="x" SharePointContentType="a" AdditionalConstraints="ac1"/>
        <Tab TabOrder="2" TabLabel="y" SharePointContentType="b" AdditionalConstraints="ac2"/>
      </Kartice>
    </PageLayout>

    <PageLayout name="xyzzy2">
      <Kartice>
        <Tab TabOrder="100" TabLabel="x" SharePointContentType="a" AdditionalConstraints="ac1"/>
        <Tab TabOrder="101" TabLabel="y" SharePointContentType="b" AdditionalConstraints="ac2"/>
        <Tab TabOrder="103" TabLabel="z" SharePointContentType="c" AdditionalConstraints="ac3"/>
      </Kartice>
    </PageLayout>

</PageLayouts>
</DeafultConfigurationSets>

Želim izgraditi neke kvačice na runtime strane raščlanjivanja gore. Moje Kartice ovisiti izgled stranice. Ako moj izgled stranice se zove "xyzzy2" onda želim da se jezičke 100, 101 i 103 (Kartice su u <PageLayout name = "xyzzy2">).

Evo kako to radi LINQ:

var = allTabs
              iz p u
                  XElement.Parse(theXmlToParse).
                  Elementi("PageLayouts").
                  Elementi("PageLayout")
              gdje (p.Attribute("name").Value.Equals("xyzzy2"))
              od m p.Elements("Tabs").Elementi("Tab")
              odaberite m;

          Results.Text = string.Empty;

          foreach (var aTab u allTabs)
          {
              Results.Text =
                  "Tab Order: " + aTab.Attribute("TabOrder").Vrijednost + " |" +
                  "Tab Label: " + aTab.Attribute("TabLabel").Vrijednost + " | " +
                  "SharePointContentType: " + aTab.Attribute("SharePointContentType").Vrijednost + " | " +
                  "AdditionalConstraints: " + aTab.Attribute("AdditionalConstraints").Vrijednost + "\r";
          }
