-- tinyxml不能解析大文件？
我在用tinyxml解析rss文件的时候，为什么解析比较大的文件就会出现段错误呢？提示的错误是：No executable file specified.和Use the"file"or"exec-file"command.我的代码如下：
#include <iostream>
#include <fstream>
#include "tinyxml.h"
using namespace std;
int main(int argc, char *argv[])
{ string filename = "first.xml"; TiXmlDocument *doc = new TiXmlDocument;
doc->LoadFile("first.xml"); const TiXmlElement* root = doc->RootElement();
const TiXmlNode *m=root->FirstChild();
const TiXmlElement *t = (const TiXmlElement*)m;
for( const TiXmlNode*n= t->FirstChild();n; n=n->NextSibling())
{
if(n->Type() == TiXmlNode::ELEMENT)
{
if((!strcmp(n->Value(),"title"))||(!strcmp(n->Value(),"description")))
{
const TiXmlElement *f = (const TiXmlElement*)n;
std::string mesh1 = f->GetText();
cout<< mesh1 <<endl;
}
else if(!strcmp(n->Value(),"item")) {
const TiXmlElement *e = (const TiXmlElement*)n;
for( const TiXmlNode* d=e->FirstChild();d; d=d->NextSibling())
{
if(d->Type() == TiXmlNode::ELEMENT) {
if((!strcmp(d->Value(),"title"))||(!strcmp(d->Value(),"description"))) {
const TiXmlElement *g = (const TiXmlElement*)d;
std::string mesh2 = g->GetText();
cout<< mesh2 <<endl;
}
} }
}
}
}
delete doc;
getchar();
return 0;
}
不能解析的文件是：
<?xml version=1.0 encoding=ISO-8859-1 ?>

但是将上面这个文件删减掉一些内容文件变小之后就可以解析了。
哪位达人帮帮忙呀！谢谢！
