LinQ | Paul Galvin's SharePoint Space

Hier is 'n vinnige voorbeeld gebruik van linQ 'n paar te ontleed XML en kry by die lieflike, soet eienskappe daarin.

Hier is die XML wat ek wil ontleed:

<?die xml weergawe = "1,0" encoding = utf-8" ?>
<DeafultConfigurationSets>
<PageLayouts>

    <PageLayout name = "Xyzzy">
      <Tabs>
        <Tab TabOrder = "1" TabLabel = "x" SharePointContentType = "'n" AdditionalConstraints = "AC1" />
        <Tab TabOrder = "2" TabLabel = "y" SharePointContentType = "b" AdditionalConstraints = "AC2" />
      </Tabs>
    </PageLayout>

    <PageLayout name = "xyzzy2">
      <Tabs>
        <Tab TabOrder = "100" TabLabel = "x" SharePointContentType = "'n" AdditionalConstraints = "AC1" />
        <Tab TabOrder = "101" TabLabel = "y" SharePointContentType = "b" AdditionalConstraints = "AC2" />
        <Tab TabOrder = "103" TabLabel = "z" SharePointContentType = "C" AdditionalConstraints = "AC3" />
      </Tabs>
    </PageLayout>

</PageLayouts>
</DeafultConfigurationSets>

Ek wil n paar tabs tydens looptyd deur die ontleding van die bogenoemde op te bou. My oortjies hang af op 'n bladuitleg. As my bladuitleg se naam is "xyzzy2" dan wil ek weet oortjies te kry 100, 101 en 103 (die tabs in <PageLayout name = "xyzzy2">).

Hier is die linQ wat doen dit:

allTabs =
              vanaf P
                  XElement.Parse(theXmlToParse).
                  Elemente("PageLayouts").
                  Elemente("PageLayout")
              waar (p.Attribute("Naam").Value.Equals("Xyzzy2"))
              van m in p.Elements("Tabs").Elemente("Tab")
              kies m;

          Results.Text = string.Empty;

          foreach (ATAB is allTabs)
          {
              Results.Text =
                  "Tab Bestel: " + aTab.Attribute("TabOrder").Waarde + " |" +
                  "Etiket: " + aTab.Attribute("TabLabel").Waarde + " | " +
                  "SharePointContentType: " + aTab.Attribute("SharePointContentType").Waarde + " | " +
                  "AdditionalConstraints: " + aTab.Attribute("AdditionalConstraints").Waarde + " R";
          }
