Module: REXML::StreamListener

Module REXML::StreamListener |
In: | /home/ser/Work/rexml/rexml/streamlistener.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.

Methods

attlistdecl cdata comment doctype elementdecl entity entitydecl instruction notationdecl tag_end tag_start text xmldecl

Public Instance methods

tag_start(name, attrs)

Called when a tag is encountered. @p name the tag name @p attrs an array of arrays of attribute/value pairs, suitable for use with assoc or rassoc. IE, <tag attr1="value1" attr2="value2"> will result in tag_start( "tag", # [["attr1","value1"],["attr2","value2"]])

tag_end(name)

Called when the end tag is reached. In the case of <tag/>, tag_end will be called immidiately after tag_start @p the name of the tag

text(text)

Called when text is encountered in the document @p text the text content.

instruction(name, instruction)

Called when an instruction is encountered. EG: <?xsl sheet='foo'?> @p name the instruction name; in the example, "xsl" @p instruction the rest of the instruction. In the example, "sheet='foo'"

comment(comment)

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

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 ...>

notationdecl(content)

<!NOTATION ...>

entity(content)

Called when %foo; is encountered in a doctype declaration. @p content "foo"

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
