讀取XML和多個命名空間

我試圖讓讀取XML和多個命名空間

<dc:identifier xsi:type="dcterms:URI" >bitstream link</dc:identifier>

和DC：使用等C＃在我的MVC應用程序需要幫助，因爲我是新來的XML

我想書名，出版社下面的代碼和不能得到的細節

XDocument billingData = XDocument.Load("http://publications.iadb.org/oai/request?verb=ListRecords&metadataPrefix=uketd_dc"); 
XNamespace oai_dc = XNamespace.Get("http://naca.central.cranfield.ac.uk/ethos-oai/2.0/"); 
XNamespace oai_dc1 = XNamespace.Get("http://naca.central.cranfield.ac.uk/ethos-oai/2.0/ http://naca.central.cranfield.ac.uk/ethos-oai/2.0/uketd_dc.xsd"); 
XNamespace dc = XNamespace.Get("http://purl.org/dc/elements/1.1/"); 

var billings = from billing in billingData.Descendants(oai_dc + "uketd_dc").Descendants(oai_dc1 + "dc") 
       select new Billing(billing.Element(dc + "title").Value, billing.Element(dc + "creator").Value, 
         billing.Element(dc + "description").Value, billing.Element(dc + "identifier").Value); 
allBillings.AddRange(billings.ToList<Billing>());

我不知道我是否做得正確。

我已經發布了代碼，我嘗試了頂部..請檢查 –

「*並且無法獲取詳細信息*」爲什麼？你得到一個錯誤？錯誤的結果？究竟是什麼？順便說一下，如果你發佈了清晰且縮進的代碼，這將幫助我們幫助你。 –

從上面給出的XML我試圖得到標題，貢獻者，出版商和包含.pdf鏈接的標識符..在上面的代碼嘗試顯示枚舉沒有結果。我怎麼能從上面的XML獲取這些東西.. –

您的查詢正在尋找元素本地名稱爲uketd_dc，然後dc的子孫。你沒有任何這些名稱的元素 - 這些似乎是名稱空間前綴。另外，我不確定你的oai_dc1命名空間應該是什麼。

你可能想要的是這樣的：

XNamespace uketd_dc = "http://naca.central.cranfield.ac.uk/ethos-oai/2.0/"; 
XNamespace dc = "http://purl.org/dc/elements/1.1/"; 

var billings = from e in doc.Descendants(uketd_dc + "uketddc") 
       select new Billing(
        (string)e.Element(dc + "title"), 
        (string)e.Element(dc + "creator"), 
        (string)e.Element(dc + "description"), 
        (string)e.Element(dc + "identifier") 
        );

請注意，您的XML有一些這樣的多個元素（例如標識符）。這將返回第一個。

另一個疑問其實我從OAI-PMH得到xml它實際上包含1000條記錄，但我只從下面的代碼獲取100條記錄XDocument billingData2 = XDocument.Load （「http://repository.iadb.org/oai/request?verb=ListRecords&metadataPrefix=oai_dc」）;我可以在一個請求中獲取所有記錄嗎？ –

它會得到所有人。如果它只返回100，那麼源中只有100個。我會指出在你的問題中鏈接返回的XML有100個。註釋中的鏈接不同，並返回具有不同名稱空間的不同XML - 這裏只有87條記錄。 –

XDocument billingData = XDocument.Load（「http://publications.iadb.org/oai/request?verb=ListRecords&metadataPrefix=uketd_dc」）;在xml的結尾顯示類似這樣的 MToxMDB8Mjp8Mzp8NDp8NTp1a2V0ZF9kYw ==但是直接訪問鏈接時，它顯示總共6306條記錄... –
