UTF-8和TinyXML [英] UTF-8 and TinyXML

问题描述

由于某种原因，我无法正确地从xml文件中读取数据.例如，我得到的不是Schrüder"，而是Schrüder".

我的代码:

  tinyxml2 :: XMLDocument doc;布尔打开(字符串路径){if(doc.LoadFile(path.c_str())== XML_SUCCESS)返回true；返回false；}int main(){if(open("C:\\ Users \\ Admin \\ Desktop \\ Test.xml"))cout<<成功"<<恩德尔XMLNode *节点= doc.RootElement();字符串测试= node-> FirstChild()-> GetText();cout<<测试<<恩德尔返回0;} 

XML的一部分:

 <?xml version ="1.0" encoding ="UTF-8"?>< myXML>< my:TXT_UTF8Test>Schrüder</my:TXT_UTF8Test></myXML> 

请注意，如果我将其转换为ANSI并将编码类型更改为"ISO-8859-15"，则可以正常工作.

我读到类似"LoadFile(filename，TIXML_ENCODING_UTF8)"之类的东西应该会有所帮助.但是事实并非如此(错误:无效的参数，只需要一个const char).我有最新版本的TinyXML2(我猜是?).我是在几分钟前从 https://github.com/leethomason/tinyxml2 下载的.>

有什么想法吗?

编辑:当我将字符串写入.xml或.txt文件时，它可以正常工作.eclipse ide控制台可能存在一些问题.无论如何，当我尝试通过电子邮件发送字符串时，我也遇到同样的问题.这是MailSend脚本:

  bool sendMail(std :: string params){if((int)ShellExecute(NULL，"open"，"H:\\ MailSend \\ MailSend_anhang.exe"，params.c_str()，NULL，SW_HIDE)< = 32)返回false；返回true； 

}

我在主要方法中这样调用它:

  sendMail(-f:[e-mail] -t:[e-mail] -s:Subject -b:Body" + test); 

解决方案

我认为问题出在您的终端上；您可以尝试在其他终端上运行测试代码吗?一种已知具有良好的UTF-8支持?

使用UTF-8模式的终端输出:

  $ ./a.out成功施吕德 

使用ISO-8859-15模式的终端输出:

  $ ./a.out成功施罗德 

也-请尝试并遵循 http://sscce.org/-为了后代，这是您的代码编译所需的一切(17676169.cpp):

  #include< tinyxml2.h>#include< string>#include< iostream>使用命名空间std;使用名称空间tinyxml2;tinyxml2 :: XMLDocument doc;布尔打开(字符串路径){if(doc.LoadFile(path.c_str())== XML_SUCCESS)返回true；返回false；}int main(){if(open("Test.xml"))cout<<成功"<<恩德尔XMLNode *节点= doc.RootElement();字符串测试= node-> FirstChildElement()-> GetText();cout<<测试<<恩德尔返回0;} 

编译为:

 <代码> g ++ -o 17676169 17676169.cpp -ltinyxml2 

和uuencoded Test.xml-确保使用完全相同的数据

 开始660 Test.xmlM/#] X; 6P @ = F5R< VEO; CTB，2XP(B！E; F-O9& EN9STB551& + 3 @ B/SX */&UY6 $ U，M/@ H @(`@/&UU.E185％] 55 $ 8X5& 5S =#Y38VARP [QD97(\ + VUY.E185％] 55 $ 8X/5& 5S =#X */] M> 5A-3#X *`结尾

如果您想确认这一理论，请在Eclipse中运行:

  #include< iostream>#include< string>#include< fstream>int main(){std :: ifstream ifs("Test.xml");std :: string xml_data((std :: istreambuf_iterator< char>(ifs))，std :: istreambuf_iterator< char>());std :: cout<<xml_data;} 

使用UTF-8模式的终端输出:

  $ ./17676169.cat<?xml version ="1.0" encoding ="UTF-8"?>< myXML>< my:TXT_UTF8Test>Schrüder</my:TXT_UTF8Test></myXML> 

使用ISO-8859-15模式的终端输出:

  $ ./17676169.cat<?xml version ="1.0" encoding ="UTF-8"?>< myXML>< my:TXT_UTF8Test>SchrŒder</my:TXT_UTF8Test></myXML> 

For some reason I can not read data from a xml file properly. For example instead of "Schrüder" I get something like "Schrüder".

My code:

tinyxml2::XMLDocument doc;

bool open(string path) {
    if(doc.LoadFile(path.c_str()) == XML_SUCCESS)
        return true;
    return false;
}



int main() {
    if(open("C:\\Users\\Admin\\Desktop\\Test.xml"))
    cout << "Success" << endl;

    XMLNode * node = doc.RootElement();
    string test = node->FirstChild()->GetText();

    cout << test << endl;
    return 0;
}

Part of XML:

<?xml version="1.0" encoding="UTF-8"?>
<myXML>
    <my:TXT_UTF8Test>Schrüder</my:TXT_UTF8Test>
</myXML>

Notice that if I convert it to ANSI and change the encoding type to "ISO-8859-15" it works fine.

I read that something like "LoadFile( filename, TIXML_ENCODING_UTF8 )" should help. However that's not the case (error: Invalid arguments, it just expects a const char). I have the latest version of TinyXML2 (I guess?). I downloaded it just a couple minutes ago from https://github.com/leethomason/tinyxml2.

Any ideas?

Edit: When I write the string to a .xml or .txt file it works fine. There might be some problem with the eclipse ide console. Anyway, when I try to send the string via E-Mail, I also get the same problems. Here's the MailSend script:

bool sendMail(std::string params) {

    if( (int) ShellExecute(NULL, "open", "H:\\MailSend\\MailSend_anhang.exe", params.c_str(), NULL, SW_HIDE) <= 32 )
        return false;
    return true;

}

I call it in the main method like this:

sendMail("-f:[e-mail] -t:[e-mail] -s:Subject -b:Body " + test);

解决方案

I think the problem is with your terminal; can you try run your test code in a different terminal ? one with known good UTF-8 support ?

Output with terminal in UTF-8 mode:

$ ./a.out 
Success
Schrüder

Output with terminal in ISO-8859-15 mode:

$ ./a.out 
Success
SchrÃŒder

Also - please try and follow http://sscce.org/ - for posterity sake here is your code with everything needed to compile (17676169.cpp):

#include <tinyxml2.h>
#include <string>
#include <iostream>

using namespace std;
using namespace tinyxml2;

tinyxml2::XMLDocument doc;

bool open(string path) {
    if(doc.LoadFile(path.c_str()) == XML_SUCCESS)
        return true;
    return false;
}



int main() {
    if(open("Test.xml"))
    cout << "Success" << endl;

    XMLNode * node = doc.RootElement();
    string test = node->FirstChildElement()->GetText();

    cout << test << endl;
    return 0;
}

compiled with:

g++ -o 17676169 17676169.cpp -ltinyxml2

and uuencoded Test.xml - to ensure exact same data is used

begin 660 Test.xml
M/#]X;6P@=F5R<VEO;CTB,2XP(B!E;F-O9&EN9STB551&+3@B/SX*/&UY6$U,
M/@H@("`@/&UY.E185%]55$8X5&5S=#Y38VARP[QD97(\+VUY.E185%]55$8X
/5&5S=#X*/"]M>5A-3#X*
`
end

Edit 1:

If you want to confirm this theory - run this in eclipse:

#include <iostream>
#include <string>
#include <fstream>

int main()
{
    std::ifstream ifs("Test.xml");
    std::string xml_data((std::istreambuf_iterator<char>(ifs)), std::istreambuf_iterator<char>());
    std::cout << xml_data;
}

Output with terminal in UTF-8 mode:

$ ./17676169.cat 
<?xml version="1.0" encoding="UTF-8"?>
<myXML>
    <my:TXT_UTF8Test>Schrüder</my:TXT_UTF8Test>
</myXML>

Output with terminal in ISO-8859-15 mode:

$ ./17676169.cat 
<?xml version="1.0" encoding="UTF-8"?>
<myXML>
    <my:TXT_UTF8Test>SchrÃŒder</my:TXT_UTF8Test>
</myXML>
