Class Overview

This class is responsible for scanning XML document structure and content. The scanner acts as the source for the document information which is communicated to the document handler.

This component requires the following features and properties from the component manager that uses it:

Public Constructors

public XML11DocumentScannerImpl ()

Default constructor.

Protected Methods

protected String getVersionNotSupportedKey ()

protected boolean isInvalid (int value)

protected boolean isInvalidLiteral (int value)

protected int isUnchangedByNormalization (XMLString value)

Checks whether this string would be unchanged by normalization.

Returns
  • -1 if the value would be unchanged by normalization, otherwise the index of the first whitespace character which would be transformed.

protected boolean isValidNCName (int value)

protected boolean isValidNameChar (int value)

protected boolean isValidNameStartChar (int value)

protected boolean isValidNameStartHighSurrogate (int value)

protected void normalizeWhitespace (XMLString value, int fromIndex)

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

protected void normalizeWhitespace (XMLString value)

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

protected boolean scanAttributeValue (XMLString value, XMLString nonNormalizedValue, String atName, boolean checkEntities, String eleName)

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

Parameters
value The XMLString to fill in with the value.
nonNormalizedValue The XMLString to fill in with the non-normalized value.
atName The name of the attribute being parsed (for error msgs).
checkEntities true if undeclared entities should be reported as VC violation, false if undeclared entities should be reported as WFC violation.
eleName The name of element to which this attribute belongs.
Returns
  • true if the non-normalized and normalized value are the same Note: This method uses fStringBuffer2, anything in it at the time of calling is lost.
Throws
IOException
XNIException

protected int scanContent ()

Scans element content.

Returns
  • Returns the next character on the stream.
Throws
IOException
XNIException

protected boolean scanPubidLiteral (XMLString literal)

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 The string to fill in with the public ID literal.
Returns
  • True on success. Note: This method uses fStringBuffer, anything in it at the time of calling is lost.
Throws
IOException
XNIException

protected boolean versionSupported (String version)
