我有下面的代码片段中,我想打印一些语句到一个XML文件中:For循环没有得到执行
void parseXML::writeStruct(std::fstream& abc,std::string prnt)
{
for (map<string,struct structSet>::iterator it = structData.begin();it != structData.end();it++)
{
if (((it->second.parent.compare("")==0) && (it->second.written == false)))
{
bool write = true;
if (it->second.type.compare("")==0)
{
for (set<std::string>::iterator i = it->second.fields.begin(); i != it->second.fields.end(); i++)
{
map<string,struct fieldSet>::iterator fd = fieldData.find(*i);
if (fd != fieldData.end())
{
std::string type = fd->second.type;
map<string,struct structSet>::iterator ntC = structData.find(type);
if (ntC != structData.end())
{
if (ntC->second.type.compare("") != 0)
{
map<string,struct structSet>::iterator ntC = structData.find(ntC->second.type);
if (ntC == structData.end()|| ntC->second.type.compare("")!= 0||ntC->second.written == false)
{
continue;
}
}
else
{
map<string,struct structSet>::iterator ntC = structData.find(ntC->second.type);
if (ntC->second.parent.compare(it->second.name))
{
}
else if (ntC->second.written == true)
{
abc << INDENT << "\t" <<"\t" << "<nonterminal ref= \"" << ntC->second.name.c_str() << "\">" << std::endl;
abc << INDENT << "\t" << "\t" <<"\t" << "<name>" << fd->second.name.c_str() << "</name>" << std::endl;
abc << INDENT << "\t"<< "\t" << "</nonterminal >" << std::endl;
}
}
}
的问题是,它不执行第一for
循环:
for (map<string,struct structSet>::iterator it = structData.begin(); it != structData.end(); it++)
这有什么可能的原因?
唯一可能的原因是:'structData '是空的。 – 2012-07-31 22:30:26
你的缩进遍布整个地方。如果可能,清理它。 – Wug 2012-07-31 22:31:05
我可以推荐一些重构吗? [箭头代码](http://www.codinghorror.com/blog/2006/01/flattening-arrow-code.html)很难理解,难以调试和难以维护。 – 2012-07-31 22:31:14
