About: msxml3: Partially implement ::setAttributeNode()

[Joris Huizer]

Hello,

In proposed patch msxml3: Partially implement ::setAttributeNode()
I think I found a little possible memory leak:

+    name = xmlChar_from_wchar(nameW);
+    value = xmlChar_from_wchar(V_BSTR(&valueW));
+
+    if (!name || !value)
+    {
+        SysFreeString(nameW);
+        VariantClear(&valueW);
+        return E_OUTOFMEMORY;
+    }

Wouldn't you need to free memory allocated for both name and value, in case one of the allocations succeeded ?

HTH,
Joris

Yes, I already spotted this, will resend whole set anyway.
