Module REXML::StreamListener
In: temp/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.


Public Instance methods

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.

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

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

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"

Called when the doctype is done


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

<!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 "">
 ["open-hatch", "SYSTEM", "\"\""]
 <!ENTITY open-hatch PUBLIC "-//Textuality//TEXT Standard open-hatch boilerplate//EN" "">
 ["open-hatch", "PUBLIC", "\"-//Textuality//TEXT Standard open-hatch boilerplate//EN\"", "\"\""]
 <!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"]

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’"


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

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"]])

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

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
