>Thread Next - XSV 2.10 IDC-XPath problem when using "child::"
Date: 10/19/2005 5:06:00 AM
any DTD-focused newsgroup or mailing list. I have an XML file in which some attributes are set to "", e.g., <entry id="4" type=""> and cannot find any way to allow this in the DTD. The DTD specifies a list of possible values for type and if I try to add "" to the list, e.g., by writing <!ENTITY % type "(foo|bar|)">, the parser complains that "the name token is required in the enumerated type list for the "type" attribute declaration.". Similarly if I try to make the attribute implied rather than required I still get the error that "" is not a valid value for the type attribute (I naively thought that an empty attribute might be equated to a missing one). So I am really stumped. Are empty attributes possible at all? FWIW the parser used is XOM, which uses Xerces2 underneath. From mike@s... Wed Oct 19 08:24:25 2005 Received: from lisa.w
