module REXML # 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. module StreamListener # 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"]]) def tag_start name, attrs end # 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 def tag_end name end # Called when text is encountered in the document # @p text the text content. def text text end # 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'" def instruction name, instruction end # Called when a comment is encountered. # @p comment The content of the comment def comment comment 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.
