bool CMarkup::SetChildData( MCD_CSTR szData, int nFlags = 0 );
bool CMarkup::SetChildData( int nValue );

Call SetChildData to replace the child position element's contents with the szData string value. This will remove any child elements of the child position element if any. It returns false if there is no child position.

As with SetData, the MNF_WITHCDATA and MNF_WITHREFS flags can be used to affect how the data value is stored.

As explained in more detail for SetData, with the MNF_WITHCDATA flag the generated CDATA Section is split wherever sData contains the ]]> end delimiter. See CDATA Sections.
