WriteStartElement (Compact 7)

3/12/2014

This method writes out the specified start tag and associates it with the specified namespace.

Syntax

HRESULT WriteStartElement (
  const WCHAR* pwszPrefix,
  const WCHAR* pwszLocalname,
  const WCHAR* pwszNamespaceUri
);

Parameters

• pwszPrefix
  The namespace prefix of the element. A NULL value is the same as an empty string.

• pwszLocalname
  The local name of the element. A NULL value is not valid.

• pwszNamespaceUri
  The namespace URI of the element. NULL is the same as an empty string.

Return Value

This method returns S_OK if no error is generated.

Remarks

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

A program must call WriteEndElement 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 code creates an element:

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

Calling WriteStartDocument is the same as calling WriteProcessingInstruction passing a name of "xml" as an argument. Therefore, a program cannot successfully call both WriteStartDocument and WriteProcessingInstruction passing the name "xml" for the same document. It is valid to call WriteStartDocument and WriteProcessingInstruction for processing instructions that have a name other than the name "xml".
