删除根节点但保留所有 child 个节点

Question

我有这个 xml 是通过

解析的

<ns0:Root xmlns:ns0="http://Core.Schemas.SouCurrencyRate">
    <Test>
        <CurrencyCode>SEKAUDPMI</CurrencyCode>
        <CurrencyType>AUD</CurrencyType>
        <CurrencyDate>2019 Juni</CurrencyDate>
        <CurrencyRate>6.5656</CurrencyRate>
        <RecordCreated>2019-06-30</RecordCreated>
        <RecordCreatedSOP>2019-06-01</RecordCreatedSOP>
    </Test>
    <Test>
        <CurrencyCode>SEKBRLPMI</CurrencyCode>
        <CurrencyType>BRL</CurrencyType>
        <CurrencyDate>2019 Juni</CurrencyDate>
        <CurrencyRate>2.4376</CurrencyRate>
        <RecordCreated>2019-06-30</RecordCreated>
        <RecordCreatedSOP>2019-06-01</RecordCreatedSOP>
    </Test>
    <Test>
        <CurrencyCode>SEKCADPMI</CurrencyCode>
        <CurrencyType>CAD</CurrencyType>
        <CurrencyDate>2019 Juni</CurrencyDate>
        <CurrencyRate>7.0771</CurrencyRate>
        <RecordCreated>2019-06-30</RecordCreated>
        <RecordCreatedSOP>2019-06-01</RecordCreatedSOP>
    </Test>
    <Test>
        <CurrencyCode>SEKCHFPMI</CurrencyCode>
        <CurrencyType>CHF</CurrencyType>
        <CurrencyDate>2019 Juni</CurrencyDate>
        <CurrencyRate>951.7346</CurrencyRate>
        <RecordCreated>2019-06-30</RecordCreated>
        <RecordCreatedSOP>2019-06-01</RecordCreatedSOP>
    </Test>
</ns0:Root>

xml 有 ("Test") child 个节点经常出现。我需要做的实际上是删除 (" <ns0:Root xmlns:ns0="http://Core.Schemas.SouCurrencyRate"> ")

所以 XML 输出是

<Test>
    <CurrencyCode>SEKAUDPMI</CurrencyCode>
    <CurrencyType>AUD</CurrencyType>
    <CurrencyDate>2019 Juni</CurrencyDate>
    <CurrencyRate>6.5656</CurrencyRate>
    <RecordCreated>2019-06-30</RecordCreated>
    <RecordCreatedSOP>2019-06-01</RecordCreatedSOP>
</Test>
<Test>
    <CurrencyCode>SEKBRLPMI</CurrencyCode>
    <CurrencyType>BRL</CurrencyType>
    <CurrencyDate>2019 Juni</CurrencyDate>
    <CurrencyRate>2.4376</CurrencyRate>
    <RecordCreated>2019-06-30</RecordCreated>
    <RecordCreatedSOP>2019-06-01</RecordCreatedSOP>
</Test>

我尝试做的是

    System.Xml.XmlDocument xDoc = new System.Xml.XmlDocument();
    xDoc.Load(bizobj.Message.BodyPart.GetOriginalDataStream());


    System.Xml.XmlNode xNode = xDoc.FirstChild;
    System.Xml.XmlNode xParent = xNode.ParentNode;
    System.Xml.XmlNodeList xChilds = xNode.ChildNodes;
    xDoc.RemoveChild(xNode);
    foreach (System.Xml.XmlNode node in xChilds)
    {
        xParent.AppendChild(node);
    }

但主要问题是返回的 xml 只包含一个 child ("Test") 而不是其他的。

我也尝试过使用 Linq，我在 post

上找到了这个

XDocument input = XDocument.Load("input.xml");
XElement firstChild = input.Root.Elements().First();

但这 returns 同样的事情对我的情况没有帮助。

有人能帮我正确的方向吗？

谢谢。

Answer 1

如果您真的只需要文本字符串，最快的方法是在 Root XElement:

上使用 XmlReader

XDocument xDoc = XDocument.Parse(bizobj.Message.BodyPart.GetOriginalDataStream());
XElement root = xDoc.Root;
XmlReader reader = root.CreateReader();
reader.MoveToContent();
string txt = reader.ReadInnerXml();

Answer 2

如果有人想看一下并使用它，就把我的最终代码放在这里。不管怎么说，Filburt 是让我走向正确方向的人，所以看起来也像他一样。

 System.Xml.XmlDocument xDoc = new System.Xml.XmlDocument();
        xDoc.Load(bizobj.Message.BodyPart.GetOriginalDataStream());
        string output = xDoc.DocumentElement.InnerXml;
    byte[] byteArray = Encoding.ASCII.GetBytes(output);
    MemoryStream stream = new MemoryStream(byteArray);

    stream.Position = 0;
    bizobj.Message.BodyPart.Data = stream;


    return bizobj;
