Support for the Ruby 2.4 series has ended. See here for reference.
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.
start_document end_document doctype elementdecl attlistdecl entitydecl notationdecl cdata xmldecl comment
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.
# File rexml/sax2listener.rb, line 53 def attlistdecl(element, pairs, contents) end
Called when <![CDATA[ … ]]> is encountered in a document. @p content “…”
# File rexml/sax2listener.rb, line 81 def cdata content end
# File rexml/sax2listener.rb, line 36 def characters text end
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”
# File rexml/sax2listener.rb, line 46 def doctype name, pub_sys, long_name, uri end
<!ELEMENT …>
# File rexml/sax2listener.rb, line 56 def elementdecl content end

# File rexml/sax2listener.rb, line 30 def end_prefix_mapping prefix end
<!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):
<!ENTITY % YN '"Yes"'> ["%", "YN", "\"Yes\""] <!ENTITY % YN 'Yes'> ["%", "YN", "Yes"] <!ENTITY WhatHeSaid "He said %YN;"> ["WhatHeSaid", "He said %YN;"] <!ENTITY open-hatch SYSTEM "http://www.textuality.com/boilerplate/OpenHatch.xml"> ["open-hatch", "SYSTEM", "http://www.textuality.com/boilerplate/OpenHatch.xml"] <!ENTITY open-hatch PUBLIC "-//Textuality//TEXT Standard open-hatch boilerplate//EN" "http://www.textuality.com/boilerplate/OpenHatch.xml">

Called when an XML PI is encountered in the document. EG: <?xml version=“1.0” encoding=“utf”?> @p version the version attribute value. EG, “1.0” @p encoding the encoding attribute value, or nil. EG, “utf” @p standalone the standalone attribute value, or nil. EG, nil @p spaced the declaration is followed by a line break

Called when a comment is encountered. @p comment The content of the comment
