我在插入一个group节点时，发生了如下的异常

Message "Element '{http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-04-11T09:28:40}Contacts' is unexpected according to content model of parent element '{http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-04-11T09:28:40}myFields'./r/nExpecting: {http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-04-11T09:28:40}Resources./r/n" string

下面是我的代码：

IXMLDOMNode nodeEntry, node;

            //set the projectid
            IXMLDOMDocument2 tempDom = (IXMLDOMDocument2)thisXDocument.DOM;
            tempDom.setProperty("SelectionLanguage", "XPath");
            tempDom.setProperty("SelectionNamespaces",
                "xmlns:dfs=/"" + "http://schemas.microsoft.com/office/infopath/2003/dataFormSolution" +
                "/" xmlns:my=/"http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-04-11T09:28:40/"");
            //nodeEntry = tempDom.documentElement.selectSingleNode("my:Tasks");
            //node = nodeEntry.cloneNode(true);
            //nodeEntry.parentNode.appendChild(node);
            try
            {
                nodeEntry = tempDom.documentElement.selectSingleNode("my:Contacts");
                node = nodeEntry.cloneNode(true);
                nodeEntry.parentNode.appendChild(node);
            }
            catch (Exception ex)
            {

}

马上在网上找了一下，没有找到具体的原因，不过可以肯定是因为我们在设计infopath时对group node做过某些修改造成的。

解决方法很简单，使用insertBefore代替appendChild即可。

// Write your code here.
IXMLDOMNode nodeEntry, node;

            //set the projectid
            IXMLDOMDocument2 tempDom = (IXMLDOMDocument2)thisXDocument.DOM;
            tempDom.setProperty("SelectionLanguage", "XPath");
            tempDom.setProperty("SelectionNamespaces",
                "xmlns:dfs=/"" + "http://schemas.microsoft.com/office/infopath/2003/dataFormSolution" +
                "/" xmlns:my=/"http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-04-11T09:28:40/"");
            //nodeEntry = tempDom.documentElement.selectSingleNode("my:Tasks");
            //node = nodeEntry.cloneNode(true);
            //nodeEntry.parentNode.appendChild(node);
            try
            {
                nodeEntry = tempDom.documentElement.selectSingleNode("my:Contacts");
                node = nodeEntry.cloneNode(true);
                nodeEntry.parentNode.insertBefore(node, nodeEntry);
            }
            catch (Exception ex)
            {

}
