A template for stream parser listeners. Note that the declarations (attlistdecl, elementdecl, etc) are trivially processed; REXML doesn’t yet handle doctype entity declarations, so you have to parse them out yourself.

WARNING These methods are certainly going to change, until DTDs are fully supported. Be aware of this.

If a doctype includes an ATTLIST declaration, it will cause this method to be called. The content is the declaration itself, unparsed. EG, <!ATTLIST el attr CDATA #REQUIRED> will come to this method as “el attr CDATA #REQUIRED”. This is the same for all of the .*decl methods.

Handles a doctype declaration. Any attributes of the doctype which are not supplied will be nil. # EG, <!DOCTYPE me PUBLIC “foo” “bar”> @p name the name of the doctype; EG, “me” @p pub_sys “PUBLIC”, “SYSTEM”, or nil. EG, “PUBLIC” @p long_name the supplied long name, or nil. EG, “foo” @p uri the uri of the doctype, or nil. EG, “bar”

<!ENTITY ...> The argument passed to this method is an array of the entity declaration. It can be in a number of formats, but in general it returns (example, result):
