I just tried a1 as you suggested, but that didn't work... I also tried to use IE to view the XML but it gives me the same error, even when i change the line and the DTD to:<!DOCTYPE Protocols [ <!ELEMENT Protocols (Protocol)> <!ELEMENT Protocol (Title, Category, Keywords, Uses, Description, Requirements, Method)> <!ATTLIST Protocol number ID #REQUIRED> <!ELEMENT Title (#PCDATA)> <!ELEMENT Category (#PCDATA)> <!ELEMENT Keywords (#PCDATA)> <!ELEMENT Uses (#PCDATA)> <!ELEMENT Description (#PCDATA)> <!ELEMENT Requirements (#PCDATA)>
