我已经尝试了所有我能想到的向前和向后的东西，我已经一次又一次地计算和记录了我的和/或，但这个外部dtd文件仍然被消息无效：＆＃34; XML解析错误@line 30（最后一行包含＆＃34;]＆gt;＆＃34;）：期望开始标记，＆＃39;＆lt;＆＃39;没找到。＆＃34;谁能帮我吗？太多了！

Answer 1

由于这是一个外部DTD，您的XML文件中是否还有引用此DTD的DOCTYPE声明？如果是这样，您需要从DTD中删除doctype。

这是一个尝试的例子，它注释掉了：

<!--<!DOCTYPE items [-->
<!ELEMENT items (item+)>
<!ELEMENT item     (description, country, sellingPrice, cost, quantityOnHand, 
                    backorderedAmount, dateLastReceived, quantitySoldYearToDate, 
                    warehouseSection, warehouseShelve, remarks, supplier, supplier+)>
<!ATTLIST item itemNumber ID #REQUIRED>     
<!ELEMENT description  (#PCDATA)>
<!ELEMENT country    (#PCDATA)>
<!ELEMENT sellingPrice      (#PCDATA)>
<!ATTLIST sellingPrice saleItem (Y|N) #REQUIRED>    
<!ELEMENT cost  (#PCDATA)>
<!ELEMENT quantityOnHand (#PCDATA)>
<!ELEMENT backorderedAmount (#PCDATA)>
<!ATTLIST backorderedAmount dateOrdered NMTOKEN #IMPLIED>   
<!ELEMENT dateLastReceived   (month, day, year)>
<!ELEMENT month  (#PCDATA)>
<!ELEMENT day  (#PCDATA)>
<!ELEMENT year  (#PCDATA)>
<!ELEMENT quantitySoldYearToDate    (#PCDATA)>
<!ELEMENT warehouseSection (#PCDATA)>
<!ELEMENT warehouseShelve     (#PCDATA)>
<!ELEMENT remarks     (#PCDATA)>
<!ELEMENT supplier       (number, shipmentLeadTime, supCost)>
<!ELEMENT number  (#PCDATA)>
<!ELEMENT shipmentLeadTime  (#PCDATA)>
<!ATTLIST shipmentLeadTime unit (days|weeks) #REQUIRED>
<!ELEMENT supCost  (#PCDATA)>
