REXML::SAX2Listener

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.

Public Instance Methods

attlistdecl(element, pairs, contents) click to toggle source

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.

def attlistdecl(element, pairs, contents)
end
            
cdata(content) click to toggle source

Called when <![CDATA[ … ]]> is encountered in a document. @p content “…”

doctype(name, pub_sys, long_name, uri) click to toggle source

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”
