question: public boolean isWhitespace ( int nodeHandle ) { int type = getNodeType ( nodeHandle ) ; Node node = getNode ( nodeHandle ) ; if ( TEXT_NODE == type || CDATA_SECTION_NODE == type ) { FastStringBuffer buf = StringBufferPool . get ( ) ; while ( node != null ) { buf . append ( node . getNodeValue ( ) ) ; node = logicalNextDOMTextNode ( node ) ; } boolean b = buf . isWhitespace ( 0 , buf . length ( ) ) ; StringBufferPool . free ( buf ) ; return b ; } return false ; }
target:  Determine if the string-value of a node is whitespace
