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.

Method Details
-
scanContent
Scans element content.- Overrides:
scanContent
in classXMLDocumentFragmentScannerImpl
- Returns:
- Returns the next character on the stream.
- Throws:
IOException
org.apache.xerces.xni.XNIException
-
scanAttributeValue
protected boolean scanAttributeValue(org.apache.xerces.xni.XMLString value, org.apache.xerces.xni.XMLString nonNormalizedValue, String atName, boolean checkEntities, String eleName) throws IOException, org.apache.xerces.xni.XNIException Scans an attribute value and normalizes whitespace converting all whitespace characters to space characters. [10] AttValue ::= '"' ([^invalid input: '<'invalid input: '&'"] | Reference)* '"' | "'" ([^invalid input: '<'invalid input: '&''] | Reference)* "'"- Overrides:
scanAttributeValue
in classXMLScanner
- 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
org.apache.xerces.xni.XNIException
-
scanPubidLiteral
protected boolean scanPubidLiteral(org.apache.xerces.xni.XMLString literal) throws IOException, org.apache.xerces.xni.XNIException 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.- Overrides:
scanPubidLiteral
in classXMLScanner
- 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
org.apache.xerces.xni.XNIException
-

-
isUnchangedByNormalization
protected int isUnchangedByNormalization(org.apache.xerces.xni.XMLString value) Checks whether this string would be unchanged by normalization.- Overrides:
isUnchangedByNormalization
in classXMLScanner
- Returns:
- -1 if the value would be unchanged by normalization, otherwise the index of the first whitespace character which would be transformed.
