I have this grammar.


Document ::= <? xml version="1.0" ?> Element
Element ::= <TagName Attributes>ElementContent</TagName>
TagName ::= Name
Name ::= [a-zA-Z0-9_:\-]+
ElementContent ::= (Text | Element)*
Text ::= [^<>]+
Attributes ::= Attribute*
Attribute ::= AttributeName="[^<>"\n]*"
AttributeName ::= Name


I written it in coco/r but I don't know how distinguish between tokens
Name, Text, and token at the right of AttributeName. Help me please.
