使用C#在XML文档中插入节点 [英] Insert node in xml document using c#
问题描述
我试图在XML文档中的特定位置插入XML节点.
I was trying to insert an XML node in XML document at a specific position.
这是我的xml:
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<Body>
<readContract xmlns="http://implementation.company.schema.reference">
<ContactNumbers>10158</ContactNumbers>
<productGroups>0085</productGroups>
<indicationBalanceInfo>false</indicationBalanceInfo>
<indicationBlocked>true</indicationBlocked>
</readContract>
</Body>
</Envelope>
并且我正在尝试在标签<productGroups>0085</productGroups>
And am trying to insert another tag <productGroups>0093</productGroups> below to the tag <productGroups>0085</productGroups>
期望如下:
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<Body>
<readContract xmlns="http://implementation.company.schema.reference">
<ContactNumbers>10158</ContactNumbers>
<productGroups>0085</productGroups>
<productGroups>0093</productGroups>
<indicationBalanceInfo>false</indicationBalanceInfo>
<indicationBlocked>true</indicationBlocked>
</readContract>
</Body>
</Envelope>
使用下面的C#代码实现它.
Used the below C# code to achieve it.
XmlDocument doc = new XmlDocument();
string inputxml = this.StServiceCallActivity5.InputEnvelope.InnerXml.ToString();
//Here inputxml contains whole xml document.
string addxml = "<productGroups>0093</productGroups>";
doc.LoadXml(inputxml);
XmlDocumentFragment xmlDocFrag = doc.CreateDocumentFragment();
xmlDocFrag.InnerXml = addxml;
XmlElement parentEle = doc.DocumentElement;
parentEle.AppendChild(xmlDocFrag);
它返回类似
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<Body>
<readContract xmlns="http://implementation.company.schema.reference">
<ContactNumbers>10158</ContactNumbers>
<productGroups>0085</productGroups>
<productGroups>0093</productGroups>
<indicationBalanceInfo>false</indicationBalanceInfo>
<indicationBlocked>true</indicationBlocked>
</readContract>
</Body>
<productGroups xmlns="">0093</productGroups>
</Envelope>
是C#代码的新手，请帮助我按预期获取XML文档. 非常感谢您的帮助.
Am a newbie to C# code, kindly help me to get the XML doc as expected. your help is much appreciated.
推荐答案
执行此操作时:
XmlElement parentEle = doc.DocumentElement;
parentEle.AppendChild(xmlDocFrag);
您要将节点附加到文档的根目录.您可能想要选择应该附加该项目的实际readContract节点.例如:
You're appending the node to the root of the document. You probably wanted to select the actual readContract node that the item is supposed to be appended into. As an example:
XmlNode newNode = doc.CreateNode(XmlNodeType.Element, "productGroup", "");
newNode.InnerText = "something";
XmlNode readContractNode = doc["Envelope"]["Body"]["readContract"];
XmlElement groups = readContractNode["productGroups"];
readContractNode.InsertAfter(newNode, groups);
当然，您可能想要处理已经存在多个子productGroup元素的情况，但是想法是相同的.
Of course you'd probably want to handle the case where there are already multiple child productGroup elements, but the idea is the same.
