MFC開發xml編輯器整理

xml格式如下所示：

<CalibrationData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><CalConfig name="TEST"><CalPath number="1" name="ANT0" data="2022-10-11 20:05:51" dayLimit="999"><CalPoint key="822.500" value="1100"/><CalPoint key="1745.00" value="0.72"/><CalPoint key="1747.50" value="0.71"/> </CalPath><CalPath number="2" name="ANT1" data="2022-10-11 20:05:51" dayLimit="999"><CalPoint key="195000" value="1500"/><CalPoint key="1784.90" value="0.78"/><CalPoint key="1785.00" value="0.78"/><CalPoint key="1805.00" value="0.80"/><CalPoint key="1840.00" value="0.68"/></CalPath><CalPath number="3" name="ANT2" data="2022-10-11 20:05:51" dayLimit="999"><CalPoint key="192500" value="4100"/></CalPath><CalPath number="4" name="ANT3" data="2022-10-11 20:05:51" dayLimit="999"><CalPoint key="192500" value="2900"/></CalPath><CalPath number="5" name="ANT4" data="2022-10-11 20:05:51" dayLimit="999"><CalPoint key="35000" value="3200"/></CalPath></CalConfig> </CalibrationData>

設計步驟：
1.拖入treeControl控件，創建變量m_tree，用于顯示TEST節點下的子節點CalPath

向tree插入節點

CString strName(_T("")); HTREEITEM hCalConfig = m_tree.InsertItem(strName); m_tree.InsertItem(strName, hCalConfig);

2.拖入listControl控件，創建變量m_list，用于顯示子節點CalPoint 的屬性值

表格中插入表頭信息，并設置格式

m_list.ModifyStyle( 0, LVS_REPORT ); // 報表模式 m_list.SetExtendedStyle(m_list.GetExtendedStyle() | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT /*| LVS_EX_CHECKBOXES*/);CRect rect;m_list.GetClientRect(rect);m_list.InsertColumn(0, L"", LVCFMT_CENTER);m_list.InsertColumn(1, L"freq", LVCFMT_CENTER, rect.Width() / 2);m_list.InsertColumn(2, L"loss", LVCFMT_CENTER, rect.Width() / 2);CImageList image;image.Create(1, 25, TRUE | ILC_COLOR16, 1, 0); //設置表格的高度 m_list.SetImageList(&image, LVSIL_SMALL);m_list.DeleteColumn(0);//第一列無法居中顯示，刪除第一列

雙擊表格實現內容可編輯，需要往界面上拖入Edit Control控件

OnDblclkList(NMHDR *pNMHDR, LRESULT *pResult) {LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);// TODO: 在此添加控件通知處理程序代碼NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;m_hitRow = pNMListView->iItem;//獲得選中的行m_hitCol = pNMListView->iSubItem;//獲得選中列if (m_hitRow != -1 && m_hitCol != -1 ){/*if (pNMListView->iSubItem == 0){return;//設置第一列不可編輯}*/CRect rect;m_list.GetSubItemRect(m_hitRow, m_hitCol, LVIR_LABEL, rect);m_editListCtrl.SetWindowText(m_list.GetItemText(m_hitRow, m_hitCol));m_editListCtrl.SetParent(&m_list);m_editListCtrl.MoveWindow(&rect, TRUE);m_editListCtrl.ShowWindow(TRUE);m_editListCtrl.SetFocus();m_editListCtrl.ShowCaret();//顯示光標m_editListCtrl.SetSel(-1);}*pResult = 0; }

編輯框中的光標消失后，將數據保存到表格中

OnKillfocusEdit() {// TODO: 在此添加控件通知處理程序代碼CString str;m_editListCtrl.GetWindowText(str); //得到用戶輸入的新的內容m_list.SetItemText(m_hitRow, m_hitCol, str); //設置編輯框的新內容m_editListCtrl.ShowWindow(SW_HIDE); //應用編輯框//同步節點中保存的信息if (!m_hEditItem){return;}CString text = m_tree.GetItemText(m_hEditItem); //CalPoint節點，將界面上修改的參數保存到m_mapDataMTmap<CString, CalPath>::iterator ite = m_mapDataMT.find(text);if (ite == m_mapDataMT.end()){return;}vector<map<CString, CString>>& vecCalPoint = ite->second.CalPathList;//修改數據的行數要小于vecCalPoint容器大小if (m_hitRow < (int)vecCalPoint.size()){map<CString, CString>& mapCalPoint = vecCalPoint[m_hitRow];if (0 == m_hitCol){mapCalPoint[L"freq"] = str;} else if (1 == m_hitCol){mapCalPoint[L"loss"] = str;}} }

3.本文借用MSXML讀取和修改xml屬性值，需要在頭文件 #import <msxml4.dll> 這是微軟庫

ReadXml(CString strXmlPath, bool bModify) {if (strXmlPath.IsEmpty()){MessageBox(_T("xml文件名為空"), _T("錯誤"), MB_ICONERROR);}MSXML2::IXMLDOMDocumentPtr pDoc;::CoInitialize(NULL);HRESULT hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument40)); if (!SUCCEEDED(hr)) { MessageBox(_T("創建DOMDocument對象失敗。\n請檢查運行環境"), _T("錯誤"), MB_ICONERROR); return;}// 讀取xmlpDoc->put_async(VARIANT_FALSE);VARIANT_BOOL bhr = pDoc->load((_variant_t)strXmlPath);if (bhr != VARIANT_TRUE) {MessageBox(_T("無法正確讀取xml文件"), _T("錯誤"), MB_ICONERROR);return;}// 根節點取得MSXML2::IXMLDOMElementPtr root = pDoc->documentElement;// 取得根節點的名字_variant_t strRootName = root->nodeName;_bstr_t wstrRootName(strRootName.bstrVal);MSXML2::IXMLDOMNodeListPtr nodeList = root->GetchildNodes();// 解析CalibrationData的子節點ReadCalConfig(nodeList, bModify);if (bModify){pDoc->save((_variant_t)strXmlPath);} } ReadCalConfig(MSXML2::IXMLDOMNodeListPtr nodeList, bool bModify ) {int ilength = nodeList->Getlength();for (int nodeCount = 0; nodeCount < ilength; nodeCount++) {MSXML2::IXMLDOMNodePtr nodePtr = nodeList->nextNode();_variant_t strNodeName = nodePtr->GetnodeName();_variant_t strNodeValue = nodePtr->GetnodeValue();// 取得節點的屬性值MSXML2::IXMLDOMNamedNodeMapPtr pDOMAttrList= nodePtr->Getattributes();MSXML2::IXMLDOMNodePtr pDOMAttr= pDOMAttrList->Getitem(0); CString cstrValue = (CString)(char*)pDOMAttr->GetnodeName();if (0 == CString(L"name").CompareNoCase(cstrValue)){CString strName =pDOMAttr->GetnodeTypedValue();//向combox插入CalConfig節點列表m_comNodeList.AddString(strName);int nSel = m_comNodeList.GetCurSel();CString cstrEditNode = _T("");if (nSel > -1){m_comNodeList.GetLBText(nSel, cstrEditNode);}//判斷combox控件中，當前名字是否跟xml的節點名字一樣if (cstrEditNode == strName && bModify){ReadCalPath(nodePtr->GetchildNodes(), true);}else if (cstrEditNode == strName && !bModify){m_hCalConfig = m_tree.InsertItem(strName);// 讀取指定節點的 CalConfig節點下的子節點ReadCalPath(nodePtr->GetchildNodes());}}} } ReadCalPath(MSXML2::IXMLDOMNodeListPtr nodeList, bool bModify) {CString strNo;
