Question

我正在努力从元素中获取价值，来自所有元素但我只能得到第一个。这是我使用的代码。

Dim xdoc As XDocument = root 'XDocument.Load("..\..\..\CountryState.xml") '
Dim Header As List(Of Bill) = ( _
From Head In (xdoc.Elements("FILE").Elements("BILL")) _
  Select New Bill With { _
  .countryName = Head.Element("CountryName").Value,
  .Population = Head.Element("Population").Value,
  .ASG_INVOICE_NO = (From el In Head...<ASG_INVOICE_NO> Select el).First(),
  .BillDetail = (From Detail In
      (Head.Element("BILL_SUMM").Element("BILL_SUMM_DETAILS").Element("ADDRESS_GROUP").Elements   ("TARIFF")) _
     Select New BillDetail With { _
      .CIRCUIT_ID = (From D In Detail.Elements("UDFS") _
                Where D.Element("UDF").Elements("COLUMN_NAME").Value  = "CIRCUIT_ID" _
                                            Select  D.<UDF>.<UDF_VALUE>.<VALUE>.Value).FirstOrDefault() _
                                  , .CUSTOM_DESC = (From D In Detail.Elements("UDFS") _
                                         Where D.Element("UDF").Elements("COLUMN_NAME").Value    = "CUSTOM_DESC" _
                                        Select D.<UDF>.<UDF_VALUE>.<VALUE>.Value).FirstOrDefault() _
      }).ToList()}).ToList()

结果是Header-＆gt; "Panama 200000 100339" 第二行Detalle-＆gt;的详细信息"8000307.SV"

缺少或无法从XML获取的值为"10 Mbps Curacao ECP" 它显示在"8000307.SV"旁边的第二行，如Detalle-＆gt; "8000307.SV" "10 Mbps Curacao ECP"

For Each H In Header
    Console.WriteLine("Header-> " + H.countryName.Trim + "  " + H.Population.Trim + " " + H.ASG_INVOICE_NO.Trim)
      For Each D In co.BillDetail
          Console.WriteLine("Detalle->  " + D.CIRCUIT_ID + " " + D.CUSTOM_DESC)
      Next D
 Next H

提前致谢...

无法使用LINQ从XML文件中的相同分支中检索第二个值
