我是新來的C++ /解析,我將xsd文件轉換爲自動生成的cpp和頭文件。當我嘗試訪問xml文件(xmlfilename)的元素(成員函數)時,出現錯誤「Primary-expression missing before' - >'token'。C++ /分析:錯誤:預期主要表達式之前' - >'令牌。如何解決此錯誤..?
我的代碼:
#include "IMACSMsgHeaderType.h"
#include<iostream>
#include<string>
#include <memory>
#include <xercesc/util/PlatformUtils.hpp>
#include <xercesc/util/XMLString.hpp>
#include <xercesc/dom/DOM.hpp>
#include <xercesc/util/OutOfMemoryException.hpp>
#include <xercesc/parsers/XercesDOMParser.hpp>
using namespace std;
using namespace SelfTest;
int main()
{
try{
::std::auto_ptr<::SelfTest::MH> xsd (::SelfTest::MH_ ("bala.xml",::xml_schema::flags::dont_validate));
}
catch(const xml_schema::exception& e)
{
cerr<<e.what()<<endl;
}
cout<<xsd->n();
return 1;
}
編譯器輸出:
[email protected]:~/Desktop/private> make
g++ -c test_classParsing.cpp
test_classParsing.cpp: In function ‘int main()’:
test_classParsing.cpp:26: error: expected primary-expression before ‘->’ token
make: *** [.o] Error 1
誰能解釋一下什麼是主表達錯誤?我該如何解決這個問題?

我不知道在哪裏我錯了,請一些一個導向me..Thanks提前
哪裏是'n()'聲明? – iammilind 2011-06-14 05:32:39
':: SelftTest :: MH'和':: SelfTest :: MH_'有什麼區別?它不應該是:: :: std :: auto_ptr <:: SelfTest :: MH> xsd(new :: SelfTest :: MH(xmlFilename,xml_schema :: flags :: dont_validate));'? – 2011-06-14 05:32:49
沒有足夠的信息。 – 2011-06-14 05:34:46
