XML is not a Java but an intermediate language used to connect various languages such as Java files to C + + files for multi-platform multi-software data interchange configuration files
XML format file <> angle brackets Very Important The XML file is opened by default as a browser
XML needs to be aware that the first line is dead format? The following is the XML file format Note Do not add space (will be error)
Symbols cannot be written in Chinese input notation cannot be nested <!------<!----->---> Error
Each XML can have only one root element it completely includes other elements, paying attention to the structure hierarchy
Definition symbols: <:=< >:=> &:=& &qwot:= "&apos:="
Why do you define symbols? Using symbols in XML can break the compilation structure
The ID represents the unique attribute in the text <book id= "modified name" > The name must have a meaning, preferably not a B c so named
<! [cdatp[]> This is a special input box you can enter text in the second bracket without using a definition symbol when there are a large number of symbols to be entered, but do not use the []
