Normalize whitespace in an XMLString converting all whitespace characters to space characters.

Convenience function used in all XML scanners.

Resolves character entity references.

Parameters

entityName:String

the name of the entity

stringBuffer:XMLStringBuffer

the current XMLStringBuffer to append the character to.

Returns:boolean

true if resolved, false otherwise

Scans an attribute value and normalizes whitespace converting all whitespace characters to space characters. [10] AttValue ::= '"' ([^<&"] | Reference)* '"' | "'" ([^<&'] | Reference)* "'"

Parameters

value:XMLString

The XMLString to fill in with the value.

nonNormalizedValue:XMLString

The XMLString to fill in with the non-normalized value.

atName:String

The name of the attribute being parsed (for error msgs).

attributes:XMLAttributes

The attributes list for the scanned attribute.

attrIndex:int

The index of the attribute to use from the list.

checkEntities:boolean

true if undeclared entities should be reported as VC violation, false if undeclared entities should be reported as WFC violation.

eleName:String

The name of element to which this attribute belongs.

isNSURI:boolean

a flag indicating whether the content is a Namespace URI

Note

This method uses fStringBuffer2, anything in it at the time of calling is lost.

Scans a character reference and append the corresponding chars to the specified buffer.

[66] CharRef ::= '&#' [0-9]+ ';' | '&#x' [0-9a-fA-F]+ ';'

Parameters

buf:XMLStringBuffer

the character buffer to append chars to

buf2:XMLStringBuffer

the character buffer to append non-normalized chars to

Returns:int

the character value or (-1) on conversion failure

Scans a comment.

[15] Comment ::= '<!--' ((Char - '-') | ('-' (Char - '-')))* '-->'

Parameters

text:XMLStringBuffer

The buffer to fill in with the text.

Scans External ID and return the public and system IDs.

Parameters

identifiers:String[]

An array of size 2 to return the system id, and public id (in that order).

optionalSystemId:boolean

Specifies whether the system id is optional

Note

This method uses fString and fStringBuffer, anything in them at the time of calling is lost.

Scans a processing instruction.

[16] PI ::= '<?' PITarget (S (Char* - (Char* '?>' Char*)))? '?>'
[17] PITarget ::= Name - (('X' | 'x') ('M' | 'm') ('L' | 'l'))

Scans a processing data. This is needed to handle the situation where a document starts with a processing instruction whose target name starts with "xml". (e.g. xmlfoo) This method would always read the whole data. We have while loop and data is buffered until delimeter is encountered.

Parameters

target:String

The PI target

data:XMLStringBuffer

The string to fill in with the data

Scans a pseudo attribute.

Parameters

scanningTextDecl:boolean

True if scanning this pseudo-attribute for a TextDecl; false if scanning XMLDecl. This flag is needed to report the correct type of error.

value:XMLString

The string to fill in with the attribute value.

Returns:String

The name of the attribute

Note

This method uses fStringBuffer2, anything in it at the time of calling is lost.

Scans public ID literal. [12] PubidLiteral ::= '"' PubidChar* '"' | "'" (PubidChar - "'")* "'" [13] PubidChar::= #x20 | #xD | #xA | [a-zA-Z0-9] | [-'()+,./:=?;!*#@$_%] The returned string is normalized according to the following rule, from http://www.w3.org/TR/REC-xml#dt-pubid: Before a match is attempted, all strings of white space in the public identifier must be normalized to single space characters (#x20), and leading and trailing white space must be removed.

Parameters

literal:XMLString

The string to fill in with the public ID literal.

Returns:boolean

True on success

Note

This method uses fStringBuffer, anything in it at the time of calling is lost.

Scans surrogates and append them to the specified buffer.

Parameters

buf:XMLStringBuffer

The StringBuffer to append the read surrogates to.

Returns:boolean

True if it succeeded.

Scans an XML or text declaration.

[23] XMLDecl ::= '<?xml' VersionInfo EncodingDecl? SDDecl? S? '?>'
[24] VersionInfo ::= S 'version' Eq (' VersionNum ' | " VersionNum ")
[80] EncodingDecl ::= S 'encoding' Eq ('"' EncName '"' |  "'" EncName "'" )
[81] EncName ::= [A-Za-z] ([A-Za-z0-9._] | '-')*
[32] SDDecl ::= S 'standalone' Eq (("'" ('yes' | 'no') "'")
                | ('"' ('yes' | 'no') '"'))

[77] TextDecl ::= '<?xml' VersionInfo? EncodingDecl S? '?>'

Parameters

scanningTextDecl:boolean

True if a text declaration is to be scanned instead of an XML declaration.

pseudoAttributeValues:String[]

An array of size 3 to return the version, encoding and standalone pseudo attribute values (in that order)

Note

This method uses fString, anything in it at the time of calling is lost.
