^Module REXML::SAX2Listener

In:	rexml/sax2listener.rb

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

start_document()

end_document()

start_prefix_mapping(prefix, uri)

end_prefix_mapping(prefix)

start_element(uri, localname, qname, attributes)

end_element(uri, localname, qname)

characters(text)

processing_instruction(target, data)

doctype(name, pub_sys, long_name, uri)

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"

attlistdecl(content)

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.

elementdecl(content)

<!ELEMENT ...>

entitydecl(content)

<!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'", "s"]
 <!ENTITY WhatHeSaid "He said %YN;">
 ["WhatHeSaid", "\"He said %YN;\"", "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">
 ["open-hatch", "PUBLIC", "\"-//Textuality//TEXT Standard open-hatch boilerplate//EN\"", "\"http://www.textuality.com/boilerplate/OpenHatch.xml\""]
 <!ENTITY hatch-pic SYSTEM "../grafix/OpenHatch.gif" NDATA gif>
 ["hatch-pic", "SYSTEM", "\"../grafix/OpenHatch.gif\"", "\n\t\t\t\t\t\t\tNDATA gif", "gif"]

notationdecl(content)

<!NOTATION ...>

cdata(content)

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

xmldecl(version, encoding, standalone)

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

comment(comment)

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