IXMLDOMImplementation
Provides methods that are independent of any particular instance of the Document Object Model (DOM).
[Script]
Example
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0"); var oImplementation; xmlDoc.async = false; xmlDoc.load("books.xml"); if (xmlDoc.parseError.errorCode <> 0) { var myErr = xmlDoc.parseError; alert("You have error " + myErr.reason); } else { oImplementation = xmlDoc.implementation; alert(oImplementation.hasFeature("DOM", "1.0")); }
[Visual Basic]
Example
Dim xmlDoc As New Msxml2.DOMDocument50 Dim oImplementation As IXMLDOMImplementation xmlDoc.async = False xmlDoc.Load "books.xml" If (xmlDoc.parseError.errorCode <> 0) Then Dim myErr Set myErr = xmlDoc.parseError MsgBox("You have error " & myErr.reason) Else Set oImplementation = xmlDoc.implementation MsgBox oImplementation.hasFeature("DOM", "1.0") End If
[C/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.
