module REXML::StreamListener

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

attlistdecl(element_name, attributes, raw_content) click to toggle source

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.

# File lib/rexml/streamlistener.rb, line 51
def attlistdecl element_name, attributes, raw_content
end
cdata(content) click to toggle source

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

# File lib/rexml/streamlistener.rb, line 83
def cdata content
end
comment(comment) click to toggle source

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

# File lib/rexml/streamlistener.rb, line 33
def comment comment
end
doctype(name, pub_sys, long_name, uri) click to toggle source

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”

# File lib/rexml/streamlistener.rb, line 41
def doctype name, pub_sys, long_name, uri
end
doctype_end() click to toggle source

Called when the doctype is done

# File lib/rexml/streamlistener.rb, line 44
def doctype_end
end
elementdecl(content) click to toggle source

<!ELEMENT …>

# File lib/rexml/streamlistener.rb, line 54
def elementdecl content
end
entity(content) click to toggle source

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

# File lib/rexml/streamlistener.rb, line 79
def entity content
end
entitydecl(content) click to toggle source

<!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", "http://www.textuality.com/boilerplate/OpenHatch.xml"]
<!ENTITY hatch-pic SYSTEM "../grafix/OpenHatch.gif" NDATA gif>
["hatch-pic", "SYSTEM", "../grafix/OpenHatch.gif", "gif"]
# File lib/rexml/streamlistener.rb, line 72
def entitydecl content
end
instruction(name, instruction) click to toggle source

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'”

# File lib/rexml/streamlistener.rb, line 29
def instruction name, instruction
end
notationdecl(content) click to toggle source

<!NOTATION …>

# File lib/rexml/streamlistener.rb, line 75
def notationdecl content
end
tag_end(name) click to toggle source

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

# File lib/rexml/streamlistener.rb, line 19
def tag_end name
end
tag_start(name, attrs) click to toggle source

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”],])

# File lib/rexml/streamlistener.rb, line 14
def tag_start name, attrs
end
text(text) click to toggle source

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

# File lib/rexml/streamlistener.rb, line 23
def text text
end
xmldecl(version, encoding, standalone) click to toggle source

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

# File lib/rexml/streamlistener.rb, line 90
def xmldecl version, encoding, standalone
end
