Parsáil XML le LINQ | SharePoint Spás Paul Galvin ar

Seo sampla tapa ag baint úsáide as LINQ a pharsáil roinnt XML agus a fháil ar an milis, tréithe milis ann.

Seo an XML a ba mhaith liom a pharsáil:

<?xml version = "1.0" ionchódú = "UTF-8" ?>
<DeafultConfigurationSets>
<PageLayouts>

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

    <PageLayout name="xyzzy2">
      <Tabs>
        <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"/>
      </Tabs>
    </PageLayout>

</PageLayouts>
</DeafultConfigurationSets>

Ba mhaith liom a thógáil suas roinnt tabs ag runtime ag parsáil an méid sin thuas. Mo tabs ag brath Ar an leagan amach na leathanach. Is é mo ainm DM Leathanach leagan amach ar "xyzzy2" ansin ba mhaith liom a fháil tabs 100, 101 agus 103 (an tabs in <PageLayout ainm = "xyzzy2">).

Seo an LINQ go ndéanann sé:

var = allTabs
              ó p i
                  XElement.Parse(theXmlToParse).
                  Eilimintí("PageLayouts").
                  Eilimintí("PageLayout")
              Nuair a (p.Attribute("name").Value.Equals("xyzzy2"))
              ó dom i p.Elements("Tabs").Eilimintí("Tab")
              Roghnaigh m;

          Results.Text = string.Empty;

          foreach (Bhí ATAB isteach allTabs)
          {
              Results.Text =
                  "Tab Order: " + aTab.Attribute("TabOrder").Luach + " |" +
                  "Tab Label: " + aTab.Attribute("TabLabel").Luach + " | " +
                  "SharePointContentType: " + aTab.Attribute("SharePointContentType").Luach + " | " +
                  "AdditionalConstraints: " + aTab.Attribute("AdditionalConstraints").Luach + "\r";
          }
