Module: REXML::SAX2Listener

Relationships & Source Files
Defined in: lib/rexml/sax2listener.rb

Overview

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.

Instance Method Summary

Instance Method Details

#attlistdecl(element, pairs, contents)

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.

<!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">



“open-hatch”, “PUBLIC”, “-//Textuality//TEXT Standard open-hatch boilerplate//EN”, “www.textuality.com/boilerplate/OpenHatch.xml”



<!ENTITY hatch-pic SYSTEM “../grafix/OpenHatch.gif” NDATA gif>


“hatch-pic”, “SYSTEM”, “../grafix/OpenHatch.gif”, “NDATA”, “gif”
