Dynamically get random values from a set of values in xml

[duderille]

I am now in need of getting some random values from a list of values in XML. Let me explain it clearly. consider it as my XML.\[code\]<data> <value> <name>a</name> <age>1</age> </value> <value> <name>b</name> <age>2</age> </value> <value> <name>c</name> <age>3</age> </value> <value> <name>d</name> <age>4</age> </value> <value> <name>e</name> <age>5</age> </value></data>\[/code\]i have to parse 3 values dynamically in a random manner. i.e. if a,b,c are displayed once the next time when the page loaded it has to display d,b,e or any other in a random order. How i have to deal with it.
