Question : Sorting / Filtering XML Using XSL

Need to take an XML document and both re-order and filter elements.

Sample XML is attached, what I want to do is have a complete copy of this XML, with all elements, but is sorted according to salary from low to high. I also only want the 2-4 records returned based on this sort.

All I need is an XSL declaration/stylesheet that I can then do the transform on.

Again, the output needs to be the XML with all parent elements present. I know this is pretty straightforward for someone who is an XSL whiz.

TIA!

Answer : Sorting / Filtering XML Using XSL

Did you ask only few employee nodes returned? I did not noticed that. Here is a corrected version which returns the first three employee with the lowest salary.
