xml解析与保存

1、c++版

1.1解析

// 加载
BOOL CConsumStatic::LoadXmlFile(CString strXml)
{
USES_CONVERSION;
TiXmlDocument doc(T2A(strXml));
if (!doc.LoadFile())
{
ZEBRA_HANDLER_AND_RETURN(etInstrumentControl,eciUserDefine,elLog,"Cannot load statistic file.");
}

TiXmlElement *root = doc.RootElement();
TiXmlElement *device;
if (!root)
{
ZEBRA_HANDLER_AND_RETURN(etInstrumentControl,"Cannot get root statistic file.");
}
//加载device
device = root->FirstChildElement();
while (device)
{
const char *value = device->Value();
if (strcmp(value,"Camera") == 0)// 相机
{
if (device->Attribute("opennum1"))
{
m_consumStatic.camera[0].opennum = atoi(device->Attribute("opennum1"));
}
}
device = device->NextSiblingElement();
}

return TRUE;
}

1.2保存

// 保存
BOOL CConsumStatic::SaveXmlFile(CString strXml)
{
USES_CONVERSION;
TiXmlDocument *xmlDoc = new TiXmlDocument();//建立文件句柄
TiXmlDeclaration *decl = new TiXmlDeclaration("1.0","utf-8","");
TiXmlElement *device = new TiXmlElement("Device");//建立一个成员
xmlDoc->LinkEndChild(decl);
xmlDoc->LinkEndChild(device);

// 相机
TiXmlElement *camera = new TiXmlElement("Camera");
device->LinkEndChild(camera);
camera->SetAttribute("opennum1",m_consumStatic.camera[0].opennum);

xmlDoc->SaveFile(T2A(strXml));
delete xmlDoc;

return TRUE;
}
