如何获得数据区的信息啊？给源代码的加分。

[西山小月]

用第三方的库吧，自己写有点麻烦

[hackwolfoscar]

你用VC的话，就相当费事了。

可以调用COM组件来做。

[白云飘飘飘]

使用MSXML，MSDN中有SDK。

[woyaowenzi]

我这里有一段乱七八糟的代码，你可以参考一下：
1. 解析XML你需要引用一个dll
#import <msxml4.dll>

typedef MSXML2::IXMLDOMDocument2Ptr LPXMLDocument;
typedef MSXML2::IXMLDOMElementPtr LPXMLElement;
typedef MSXML2::IXMLDOMNodePtr LPXMLNode;
typedef MSXML2::IXMLDOMNodeListPtr LPXMLNodeList;
typedef MSXML2::IXMLDOMAttributePtr LPXMLAttribute;

2. 读取节点，一层层往下剥。
// Root
#define ROOTNODE L"TabControl"

// +1
#define ALIGNMENT L"Alignment"

// +1
#define TABPAGENODE L"TabPage"
#define TABPAGE_INDEX L"Index"
#define TABPAGE_TEXT L"Text"

// +2
#define BUTTONSNODE L"Buttons"

// +3
#define BUTTONNODE L"Button"
#define BUTTON_NAME L"Name"
#define BUTTON_TEXT L"Text"
#define BUTTON_VISABLE L"Visible"
#define BUTTON_INDEX L"Index"

void CTabCtrlData::ReadXMLFromFile( const wstring& filename )
{
CoInitialize(NULL);
LPXMLDocument pQueueDom = NULL;
HRESULT hr = pQueueDom.CreateInstance(__uuidof(MSXML2_DOCUMENT));
if ( FAILED(hr) || (NULL == pQueueDom) )
{
CoUninitialize();
return ;
}

pQueueDom->async = VARIANT_FALSE;
if ( pQueueDom->load(filename.c_str()) )
{
LPXMLElement pRoot =pQueueDom->GetdocumentElement();

// +1: Get the Alignment Node
LPXMLElement pAlignment = pRoot->selectSingleNode(ALIGNMENT);
_bstr_t str = pAlignment->Gettext();
setAlignStatus(str.GetBSTR());
SAFE_RELEASE_IXMLDOM(pAlignment);

// +1: Get the TabPage Node
LPXMLNodeList pTabPageList = pRoot->selectNodes(TABPAGENODE);
if (pTabPageList->Getlength() > 0)
{
for (int ix = 0; ix < pTabPageList->Getlength(); ++ix)
{
LPTABPAGE lpTabPage = new TABPAGE();
LPXMLElement tempTabPage = pTabPageList->item[ix];

// +2: Get the TabPage's subNode: index
wstring strTabPageIndex = getSingleNodeStr(tempTabPage, TABPAGE_INDEX);
lpTabPage->m_uIndex = _wtoi(strTabPageIndex.c_str());

// +2: Get the TabPage's subNode: text
lpTabPage->m_strText = getSingleNodeStr(tempTabPage, TABPAGE_TEXT);

// +2: Get the TabPage's subNode: Buttons (It's a list)
LPXMLElement pBottons = tempTabPage->selectSingleNode(BUTTONSNODE);
LPXMLNodeList pBottonList = pBottons->selectNodes(BUTTONNODE);
if (pBottonList->Getlength() > 0)
{
for (int jx = 0; jx < pBottonList->Getlength(); ++jx)
{
LPBUTTON lpButton = new BUTTON();
LPXMLElement tempButton = pBottonList->item[jx];

// +3: Get the button's subNode: Name/Text/Visible/Index
lpButton->m_strName = getSingleNodeStr(tempButton, BUTTON_NAME);
lpButton->m_strText = getSingleNodeStr(tempButton, BUTTON_TEXT);

wstring tempVisible = getSingleNodeStr(tempButton, BUTTON_VISABLE);
_wcslwr_s( const_cast<wchar_t*>(tempVisible.c_str()), tempVisible.length() + 1 );
lpButton->m_bVisible = (0 == tempVisible.compare(L"true")) ? 1 : 0;

lpButton->m_uIndex = _wtoi( getSingleNodeStr(tempButton, BUTTON_INDEX).c_str() );

// Finally, add the button to tab page's inner vector
lpTabPage->m_vBtnList.push_back(lpButton);
}
}

// Finally, add the tab page to CTabCtrlData's inner vector
this->m_vTabPageList.push_back(lpTabPage);
}
}
}

SAFE_RELEASE_IXMLDOM(pQueueDom);
CoUninitialize();
}

我的XML文件基本如下：
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<TabControl>
<Alignment>top</Alignment>

<TabPage>
<Index>1</Index>
<Text>AAAAA</Text>
<Buttons>
<Button>
<Name></Name>
<Text>A-content_1</Text>
<Visible>false</Visible>
<Index>1</Index>
</Button>
<Button>
<Name></Name>
<Text>A-content_2</Text>
<Index>2</Index>
<Visible>true</Visible>
</Button>
</Buttons>
</TabPage>

<TabPage>
<Index>2</Index>
<Text>BBBBB</Text>
<Buttons>
<Button>
<Name></Name>
<Text>B-content_1</Text>
<Visible>true</Visible>
<Index>1</Index>
</Button>
<Button>
<Name></Name>
<Text>B-content_2</Text>
<Visible>true</Visible>
<Index>2</Index>
</Button>
<Button>
<Name></Name>
<Text>B-content_3</Text>
<Visible>true</Visible>
<Index>3</Index>
</Button>
</Buttons>
</TabPage>
</TabControl>
