c# - xml 根目录中的多个命名空间

Question

我在生成 xml 根时遇到问题。我必须匹配此结构，因为 xml 的元素始终使用前缀。

<ShipmentReceiptNotification
xmlns="urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02"
xmlns:dacc="urn:rosettanet:specification:domain:Procurement:AccountClassification:xsd:codelist:01.03"
xmlns:dbpq="urn:rosettanet:specification:domain:Procurement:BookPriceQualifier:xsd:codelist:01.04"
xmlns:dccc="urn:rosettanet:specification:domain:Procurement:CreditCardClassification:xsd:codelist:01.03"
xmlns:dcrt="urn:rosettanet:specification:domain:Procurement:CustomerType:xsd:codelist:01.03"
..\..\XML\Interchange\ShipmentReceiptNotification_02_02.xsd">

如果我做类似的事情

XmlNode ShipmentReceiptNotification0Node = xmlDoc.CreateElement("ShipmentReceiptNotification", "xmlns=\"urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02\"xmlns:dacc=\"urn:rosettanet:specification:domain:Procurement:AccountClassification:xsd:codelist:01.03\"");

我得到

-ShipmentReceiptNotification xmlns="xmlns="urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02"xmlns:dacc=&

quot;urn:rosettanet:specification:domain:Procurement:AccountClassification:xsd:codelist:01.03"">

Answer 1

CreateElement的第二个参数接受正在创建的元素的命名空间的 URI，即 ShipmentReceiptNotification ， 属于。不是一大堆xmlns属性。这段代码:

XmlElement e = xmlDoc.CreateElement(
    "ShipmentReceiptNotification",
    "urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02");

生成此 XML:

<ShipmentReceiptNotification 
    xmlns="urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02" />

要生成您想要的内容，您需要向元素添加属性。像这样:

XmlElement e = xmlDoc.CreateElement("ShipmentReceiptNotification");
e.SetAttribute("xmlns", "urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02");
e.SetAttribute("xmlns:dacc", "urn:rosettanet:specification:domain:Procurement:AccountClassification:xsd:codelist:01.03");

生成此 XML:

<ShipmentReceiptNotification 
    xmlns="urn:rosettanet:specification:interchange:ShipmentReceiptNotification:xsd:schema:02.02" 
    xmlns:dacc="urn:rosettanet:specification:domain:Procurement:AccountClassification:xsd:codelist:01.03" />

请注意，这是“手动”方式。你应该玩 XmlNamespaceManager 做到“正确”。但是，这可能是一个更复杂的任务，对于您的场景来说不是必需的。
