如何使用msxml解析器创建子元素

How do I create child elements using msxml parser?

本文关键字：创建 元素 何使用 msxml      更新时间：2023-10-16

我有一个users.xml

<?xml version="1.0"?>
<Data>
    <Users>
        <User name="xyz" email="xyz@xyz.com">
                    <Tasks/>
        </User>
    </Users>
</Data>

我有一个引用到Users元素使用以下代码

IXMLDOMDocumentPtr pXMLDom;
// code to load the xml dox
IXMLDOMElementPtr pXMLDocElement = NULL;
IXMLDOMNodeListPtr pXMLUsers = NULL;
//gets <Data>
pXMLDocElement = pXMLDom->GetdocumentElement();
//gets <Users>
pXMLUsers = pXMLDocElement->childNodes;
如何在Users元素中创建子元素User呢?

我尝试在pXMLUsers上使用createElement()，但它显示IXMLDOMNodeListPtr has no member appendChild。

我不知道如何创建一个新元素。

谢谢。

您不能使用IXMLDOMNodeListPtr来附加子元素—它只是用于迭代现有的子元素。

你可以使用IXMLDOMElementPtr直接调用pXMLDocElement->appendChild()在你的文档中添加子元素

好的，我已经找到了一个解决方案，感谢TERACytE

IXMLDOMDocumentPtr pXMLDom;
// code to load the xml dox
//Creating <User>
MSXML2::IXMLDOMElementPtr pUser = pXMLDom->createNode(NODE_ELEMENT, "User", "");
//Creating <User name="">
MSXML2::IXMLDOMAttributePtr pName = pXMLDom->createAttribute("name");
pName->value = name;
//Creating <User email="">
MSXML2::IXMLDOMAttributePtr pEmail = pXMLDom->createAttribute("email");
pEmail->value = email;
//Adding name attrib to <User>
pUser->setAttributeNode(pName);
//Adding email attrib to <User>
pUser->setAttributeNode(pEmail);
//Creating <Tasks>
MSXML2::IXMLDOMElementPtr pTasks = pXMLDom->createNode(NODE_ELEMENT, "Tasks", "");
//Creating <Task>
MSXML2::IXMLDOMElementPtr pTask = pXMLDom->createNode(NODE_ELEMENT, "Task", "");
//Creating <Task name="">
MSXML2::IXMLDOMAttributePtr pTName = pXMLDom->createAttribute("name");
pTName->value = task;
//Creating <User status="">
MSXML2::IXMLDOMAttributePtr pStatus = pXMLDom->createAttribute("status");
pStatus->value = status;
//Adding name attrib to <User>
pTask->setAttributeNode(pTName);
//Adding status attrib to <User>
pTask->setAttributeNode(pStatus);
//Adding <Task> to <Tasks>
pTasks->appendChild(pTask);
//Adding <Tasks> to <User>
pUser->appendChild(pTasks);
//Selecting <Users>
MSXML2::IXMLDOMNodePtr pUsers = pXMLDom->selectSingleNode("/Data/Users");
//Adding <User> to <Users>
pUsers->appendChild(pUser);
