    JSP - XML

    If this is a really simple application, then you could read the XML directly from your JSP using JSTL XML tags. http://java.sun.com/products/jsp/jstl/ For anything more complicated, you should really use the MVC design pattern. Have a JavaBean class to model your XML, and have the JSP access...

    String.replace() with unusual characters

    ...is '\' '.' This then ensures the period is not treated as a special metacharacter. One way to get round this problem for large pieces of text is: "\\Q your text containing metachars like . + *\\E" See also: http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Pattern.html Cheers, Neil

    Sorting in foreach

    A minor variation on Dinesh's (19decsat) answer using a sub for clarity: foreach (sort byVal keys %hash) { print "$_ $hash{$_}\n"; } sub byVal { return $hash{$b} <=> $hash{$a}; } Cheers, Neil
