帮我看看我的DTD错误在哪里并修改它
外部DTD代码是:
<!ELEMENT account (deposit,payment)+>
<!ELEMENT deposit (from,amount,date,description?)>
<!ELEMENT payment (to,amount,data,description?)>
<!ELEMENT from (#PCDATA)>
<!ELEMENT to (#PCDATA)>
<!ELEMENT amount (#PCDATA)>
<!ELEMENT date (#PCDATA)>
<!ELEMENT description (#PCDATA)>
<!ATTLIST account
name CDATA #FIXED "Harold Roy"
number ID #FIXED "899-24390"
bank CDATA #FIXED "Central City Bank" >
<!ATTLIST deposit type (direct,cash,transfer,cheque) #REQUIRED>
<!ATTLIST payment
payment (atm,cheque,transfer,withdrawal) #REQUIRED
chequeNum ID #IMPLIED
>
<!ATTLIST from category income #REQUIRED>
<!ATTLIST to category (utilities|entertainment|food|clothing|cash|other) #REQUIRED>
<!ENTITY employer "Net World">
XML代码是:
