<guestDetails>
<name>Jones</name>
<city>SomewhereOnlyWeKnow</city>
<address>NiceStreet</address>
<state>NiceState</state>
</guestDetails>

及其DTD文件:
<?xml version="1.0" encoding="utf-8"?>
<!ELEMENT hotels (general+)>
<!ELEMENT general (city, address, phone, hotelDetails)>
<!ELEMENT hotelDetails (hotel_code, hotel_rank, hotel_name)>
<!ELEMENT address (#PCDATA)>
<!ELEMENT city (#PCDATA)>
<!ELEMENT hotel_rank (#PCDATA)>

<!ELEMENT guests (guest+)>
<!ELEMENT guest (id, guestDetails)>
<!ELEMENT guestDetails (name, city, address, state)>

该文件未经过验证,XMLspy输出为:
Character 'D' is grammatically unexpected
知道这意味着什么吗?
谢谢!
