L' XML ak LINQ | Paul Galvin SharePoint espas

Isit la se yon ekzanp rapide itilize LINQ pou analyser kèk XML Et obtenir nan likè, dous attributs qui.

Se isit la mwen vle analyser XML a:

<?xml vèsyon pipiti de youn = "1.0" codage = "utf 8" ?>
<DeafultConfigurationSets>
<PageLayouts>

    <Non PageLayout = "xyzzy">
      <Onglets>
        <Onglet TabOrder = "1" TabLabel = "x" SharePointContentType = "yon" AdditionalConstraints = "ac1" />
        <Onglet TabOrder = "2" TabLabel = "y" SharePointContentType = "b" AdditionalConstraints = "ac2" />
      </Onglets>
    </PageLayout>

    <Non PageLayout = "xyzzy2">
      <Onglets>
        <Onglet TabOrder = "100" TabLabel = "x" SharePointContentType = "yon" AdditionalConstraints = "ac1" />
        <Onglet TabOrder = "101" TabLabel = "y" SharePointContentType = "b" AdditionalConstraints = "ac2" />
        <Onglet TabOrder = "103" TabLabel = "z" SharePointContentType = "c" AdditionalConstraints = "ac3" />
      </Onglets>
    </PageLayout>

</PageLayouts>
</DeafultConfigurationSets>

Mwen vle pou kèk onglets nan D' te konstwi pa l' a CI-dessus. M' onglets depann sou yon paj en. Si non M' en paj se "xyzzy2" lè sa a, mwen vle pou jwenn onglets 100, 101 Et 103 (les onglets nan <Non PageLayout = "xyzzy2">).

Isit la se LINQ ki fè li:

var allTabs =
              de p i nan
                  XElement.Parse(theXmlToParse).
                  Eleman yo("PageLayouts").
                  Eleman yo("PageLayout")
              Kote (p.Attribute("non").Value.Equals("xyzzy2"))
              depi m nan p.Elements("Onglets").Eleman yo("Onglet")
              fè chwa m;

          Results.Text = chaîne.Vid;

          foreach (var aTab nan allTabs)
          {
              Results.Text =
                  "Onglet lòd: " + aTab.Attribute("TabOrder").Valè + " |" +
                  "Onglet etikèt ki: " + aTab.Attribute("TabLabel").Valè + " | " +
                  "SharePointContentType: " + aTab.Attribute("SharePointContentType").Valè + " | " +
                  "AdditionalConstraints: " + aTab.Attribute("AdditionalConstraints").Valè + "r";
          }
