Writes out the specified start tag.

Syntax

  
HRESULT WriteStartElement (  
    const WCHAR * pwszQNname,  
    UINT cwszQName);

Arguments

pwszQName
The qualified name of the element to open. NULL causes an error.

cwszQName
The length of the element name in wide-character units.

Return Value

Returns S_OK if no error is generated.

Remarks

After calling this method, an application can either write attributes or write content. To write content, use WriteComment, WriteString, or WriteStartElement.

A program must call WriteEndElement or WriteFullEndElement to close the element. The WriteEndElement method might write a full end tag, or it might close the element by using the short form. The WriteFullEndElement method always writes a full end tag.

The following example creates an element:

if (FAILED(hr = pWriter->WriteStartElement(L"containsEntity", 14)))  
{  
    wprintf(L"Error, Method: WriteStartElement, error is %08.8lx", hr);  
    return -1;  
}  
if (FAILED(hr = pWriter->WriteEntityRef(L"myEntity")))  
{  
    wprintf(L"Error, Method: WriteEntityRef, error is %08.8lx", hr);  
    return -1;  
}  
if (FAILED(hr = pWriter->WriteEndElement(L"containsEntity", 14)))  
{  
    wprintf(L"Error, Method: WriteEndElement, error is %08.8lx", hr);  
    return -1;  
}
