LINQ | Paul Galvin's SharePoint Space

Hapa ni mfano ya haraka kwa kutumia LINQ kuchanganua baadhi XML na kupata saa tamu, tamu sifa humo.

Hapa ni XML nataka Hazrat:

<?xml version="1.0" encoding="utf-8" ?>
<DeafultConfigurationSets>
<PageLayouts>

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

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

</PageLayouts>
</DeafultConfigurationSets>

Nataka kujenga tabo baadhi katika Runtime na parsing hapo juu. Tabo yangu hutegemea juu ya mpangilio wa ukurasa. Kama jina ukurasa wangu layout ni "xyzzy2" basi nataka kupata tabo 100, 101 na 103 (tabo katika <PageLayout jina = "xyzzy2">).

Hapa ni LINQ kwamba gani:

mara allTabs =
              kutoka uk katika
                  XElement.Parse(theXmlToParse).
                  Vipengele("PageLayouts").
                  Vipengele("PageLayout")
              ambapo (p.Attribute("name").Value.Equals("xyzzy2"))
              kutoka m katika p.Elements("Tabs").Vipengele("Tab")
              kuchagua m;

          Results.Text = string.Empty;

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