# module 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.

## Methods

- attlistdecl
- cdata
- comment
- doctype
- elementdecl
- entity
- entitydecl
- instruction
- notationdecl
- tag_end
- tag_start
- text
- xmldecl

## Methods

### attlistdecl

#### Arguments

content

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.

### cdata

#### Arguments

content

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

### comment

#### Arguments

comment

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

### doctype

#### Arguments

name
pub_sys
long_name
uri

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"

### elementdecl

#### Arguments

content

<!ELEMENT ...>

### entity

#### Arguments

content

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

### entitydecl

#### Arguments

content

<!ENTITY ...>

### instruction

#### Arguments

name
instruction

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'"

### notationdecl

#### Arguments

content

<!NOTATION ...>

### tag_end

#### Arguments

name

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

### tag_start

#### Arguments

name
attrs

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"]])

### text

#### Arguments

text

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

### xmldecl

#### Arguments

version
encoding
standalone

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
