| Module | REXML::StreamListener |
| In: |
|
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.
47: def attlistdecl element_name, attributes, raw_content 48: end
Called when <![CDATA[ … ]]> is encountered in a document. @p content "…"
79: def cdata content 80: end
Called when a comment is encountered. @p comment The content of the comment
32: def comment comment 33: 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. EG, "bar"
40: def doctype name, pub_sys, long_name, uri 41: end
Called when %foo; is encountered in a doctype declaration. @p content "foo"
75: def entity content 76: end
<!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 hatch-pic SYSTEM "../grafix/OpenHatch.gif" NDATA gif> ["hatch-pic", "SYSTEM", "\"../grafix/OpenHatch.gif\"", "\n\t\t\t\t\t\t\tNDATA gif", "gif"]
68: def entitydecl content 69: 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’"
28: def instruction name, instruction 29: end
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"]])
13: def tag_start name, attrs 14: end
