IXMLDOMImplementation

 

Provides methods that are independent of any particular instance of the Document Object Model (DOM).

JScript Example

Note

You can use books.xml to run this sample code.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.6.0");  
var oImplementation;  
xmlDoc.async = false;  
xmlDoc.load("books.xml");  
if (xmlDoc.parseError.errorCode != 0) {  
   var myErr = xmlDoc.parseError;  
   WScript.Echo("You have error " + myErr.reason);  
} else {  
   oImplementation = xmlDoc.implementation;  
   WScript.Echo (oImplementation.hasFeature("DOM", "1.0"));  
}  
  

Output

-1

Note

A value of -1 indicates that MSXML implements the specified feature. A value of 0 indicates the feature is not implemented.

C++ Example

IXMLDOMImplementation *pIXMLDOMImplementation = NULL;  
VARIANT_BOOL varbFlag ;  
BSTR bstrOutput = NULL;  
BSTR bstrFeature = ::SysAllocString(_T("MS-DOM"));  
HRESULT hr;  
IXMLDOMDocument *pIXMLDOMDocument = NULL;  
  
try  
{  
    // Create an instance of DOMDocument and initialize pIXMLDOMDocument.  
    // Load/create an XML fragment.  
    hr = pIXMLDOMDocument->get_implementation(&pIXMLDOMImplementation);  
  
    if(SUCCEEDED(hr) && pIXMLDOMImplementation)  
    {  
        hr = pIXMLDOMImplementation->hasFeature(bstrFeature, _T("1.0"), &varbFlag);  
        if(varbFlag == VARIANT_TRUE )  
            bstrOutput = ::SysAllocString(_T("Feature Supported"));  
        else  
            bstrOutput = ::SysAllocString(_T("Feature not Supported"));  
  
        ::MessageBox(NULL, bstrOutput, bstrFeature, MB_OK);  
        ::SysFreeString(bstrOutput);  
        bstrOutput = NULL;  
        ::SysFreeString(bstrFeature);  
        bstrFeature = NULL;  
        pIXMLDOMImplementation->Release();  
    }  
}  
catch(...)  
{  
    if(bstrOutput)  
        ::SysFreeString(bstrOutput);  
    if(bstrFeature)  
        ::SysFreeString(bstrFeature);  
    if(pIXMLDOMImplementation)  
        pIXMLDOMImplementation->Release();  
    DisplayErrorToUser();  
}  
// Release pIXMLDOMDocument when finished using it.
