【摘 要】
public static String escapeHTMLTags( String input ) {
// Check if the string is null or zero length -- if so, return what was sent in.
if( input == null || input.length() == 0 ) {
return input;
}
// Use a StringBuffer in lieu of String concatenation -- it is much more efficient this way.
StringBuffer buf = new StringBuffer();
char ch = ′ ′;
for( int i=0; ich = input.charAt(i);
if( ch == ′<′ ) {
buf.append( "<" );
}
else if( ch == ′>′ ) {
buf.append( ">" );
}
else {
buf.append( ch );
}
}
return buf.toString();
