如何读写指定的xml文件
如何读写下面指定的xml文件：
我要的信息是：
NAME，ID，Version，ModifiedDate
帮忙分析一下下面的xml？？？
<?xml version='1.0' encoding='utf-8'?>

[解决办法]
selectSingleNode("//name")
[解决办法]
http://www.polsnet.com/home/tech165_8727.html
参考一下，自己改改
[解决办法]
http://www.codeproject.com/dialog/WndFreePool.asp
[解决办法]
selectSingleNode((_bstr_t)"节点名")；找单个节点；
selectNodes(((_bstr_t)"节点名")；找具有相同名称的节点返回链表，nextNode()获取链表中的下一个；
selectSingleNode((_bstr_t)"节点名//@属性名"); 找某个节点下的某个属性点
selectNodes((_bstr_t)"节点名//@属性名"); nextNode()
分析一下你要提取的内容，这几个应该够用了
------解决方案--------------------
就以我上面写的为例：如果我要取得feature的节点名要怎样做？？？
[解决办法]
selectSingleNode((_bstr_t) "//feature "); 总是找不到啊
[解决办法]
一个找节点的完整的例子：
- C/C++ code
_bstr_t strTemp;CString m_xmlPath = "C:\\Documents and Settings\\Administrator\\桌面\\XML\\myXml.xml";MSXML::IXMLDOMDocumentPtr pDoc = NULL;pDoc.CreateInstance(__uuidof(MSXML::DOMDocument));pDoc->load(_bstr_t(m_xmlPath));MSXML::IXMLDOMNodePtr pNode = pDoc->documentElement; // 获取文档的根节点MSXML::IXMLDOMNodePtr pXmlNode = NULL; // 用于接收selectSingleNode的返回节点 pXmlNode = pNode->selectSingleNode((_bstr_t)"//yournodename");strTemp = pXmlNode->text; // 获取节点的值 AfxMessageBox(strTemp);MSXML::IXMLDOMNodeListPtr pNodeList = NULL; // 用于接收selectNodes返回的节点列表 多个nodename重名pNodeList = pNode->selectNodes((_bstr_t)"//yournodename");pXmlNode = pNodeList->item[0]; // 获取返回节点列表的第一个节点strTemp = pXmlNode->text; // 获取节点的值AfxMessageBox(strTemp);pXmlNode = pNodeList->nextNode(); // 获取节点列表的下一个节点strTemp = pXmlNode->text;AfxMessageBox(strTemp);。。。//节点名//@属性名 也是一样的
[解决办法]
<?xml version="1.0" encoding="utf-8" ?>
-<express dateformat="yyyy/M/d H:mm::SS">
+<option>
+<data>
</express>
有主节点吗
[解决办法]
不好读呀，难
[解决办法]
很简单的
[解决办法]
CMarkup的话：
- C/C++ code
CMarkup xml; if ( xml.Load("D:\\MyXml.xml") ) { //MessageBox("ok to load MyXml.xml"); xml.ResetMainPos(); if ( xml.FindChildElem("data") ) //查找data节点 { //MessageBox("data found"); xml.IntoElem(); while ( xml.FindChildElem("changerequest") ) { //MessageBox("changerequest found!"); xml.IntoElem(); CString strChangeID = xml.GetAttrib("id") MessageBox(strChangeID ); //xml.IntoElem(); while ( xml.FindChildElem("feature") )//进入layoutCategories的layouts节点 { //MessageBox("feature found!"); xml.IntoElem(); MessageBox(xml.GetAttrib("id")); //获得在这个模板下的所有页面版式的id //通过这个id,再访问这个id同名的PageLayout节点，创建控件 } xml.OutOfElem(); //指针在LayoutCategory }xml.OutOfElem(); }
