c++ - 以编程方式创建的 tinyxml xml 文件未在 Internet Explorer 中加载

Question

我为 tinyxml 遵循的所有示例都生成了我能够在 Internet Explorer 中查看的 xml 文件。

但是，当我以编程方式创建我的时，IE 中没有任何显示。不过，我可以确认 xml 文件包含我期望的所有内容。

这是创建 xml 的代码:

bool InputIO::saveDevice( const std::string & fileName, const InputDevice& device ) const
    {

        TiXmlDocument doc;
        TiXmlDeclaration* decl = new TiXmlDeclaration( "1.0", "", "" );  
        doc.LinkEndChild( decl );  
        TiXmlElement* root = new TiXmlElement("Input Devices");
        doc.LinkEndChild(root);
        TiXmlElement* dev = new TiXmlElement("Device");
        root->LinkEndChild(dev);
        dev->SetAttribute("number",1);
        for(int p = 0; p < 2; ++p)
        {
            for(int i = 0; i < NUM_KEYS; ++i)
            {
                //Primary configuration when p is 0
                InputKey key = device.getKey(InputEvent::Uniform_inputEnum(i),p == 0);

                TiXmlElement* button = new TiXmlElement("button");
                dev->LinkEndChild(button);
                button->SetAttribute("configuration",p);
                button->SetAttribute("number",i);
                button->SetAttribute("input type",key.inputType);
                button->SetAttribute("key code",key.keyCode);
                button->SetAttribute("joy axis",key.axis);
                button->SetAttribute("joy button",key.button);
                button->SetAttribute("joy stick",key.stick);

                if(key.positiveAxis)
                {
                    button->SetAttribute("axis direction","positive");
                }
                else
                {
                    button->SetAttribute("axis direction","negative");
                }
            }

        }
        doc.SaveFile(fileName.c_str());
        return true;
    }

这是生成的 xml

Answer 1

W3 XML Validator程序告诉我们有关您的 XML 的信息:

XML Parsing Error: not well-formed 
Location: http://www.w3schools.com/xml/xml_validator.asp 
Line Number 2, Column 15: <Input Devices>
                          --------------^

最后，您终止了输入设备，但空格是错误的。在那之后，您的 XML 会遇到更多问题。在这里查看如何制作您的 XML well-formed .
