一个json转xml的例子

xml的<>里面很多字符都显示为非法，所以就转了下。json用的是jsoncpp开源库

intCCMPUtility::jsonToXmlString(Json::Value value,std::string &strXml)

{

if(0 == value.size()) return -1;

std::vector<std::string> vecKeys = value.getMemberNames();

for(std::vector<std::string>::iterator it = vecKeys.begin();it != vecKeys.end();it++)

{

std::string strKey = *it;

//const char *szNum = strKey.c_str();

std::string strKeyNoSpace;

//if(isdigit(*szNum))

strKeyNoSpace = "prefix_"+strKey;/*XML tag cannot begin with a number*/

//else

//strKeyNoSpace = strKey;

replaceString(strKeyNoSpace," ","_");/*XML tag cannot include space*/

replaceString(strKeyNoSpace,"^","");/*XML tag cannot include space*/

if(value[strKey.c_str()].isArray())

{

Json::Value array = value[strKey.c_str()];

std::string strArray="";

strXml += "<"+strKeyNoSpace+">\n";

for(Json::Value::iterator itV = array.begin();itV != array.end();itV++)

{

std::string str;

if((*itV).isString())

{

str = (*itV).asString();

}

else if((*itV).isInt())

{

int nItem = (*itV).asInt();

std::ostringstream stream;

stream<<nItem;

str = stream.str();

}

if(!str.empty())

strXml += "<li>"+str+"</li>\n";

}

strXml += "</"+strKeyNoSpace+">";

}

else if(value[strKey.c_str()].isObject())

{

Json::Value ItemValue = value[strKey.c_str()];

strXml += "<"+strKeyNoSpace+">";

jsonToXmlString(ItemValue,strXml);

strXml += "</"+strKeyNoSpace+">";

}

else if(value[strKey.c_str()].isString())

{

std::string strItem = value[strKey.c_str()].asString();

if(!strItem.empty())

strXml  += "<"+strKeyNoSpace+">"+strItem+"</"+strKeyNoSpace+">\n";

}

else if(value[strKey.c_str()].isInt())

{

std::ostringstream stream;

stream << value[strKey.c_str()].asInt();

std::string strItem = stream.str();

if(!strItem.empty())

strXml  += "<"+strKeyNoSpace+">"+strItem+"</"+strKeyNoSpace+">\n";

}

}

return 0;

}
