my program is right.. but i dnt want to hardcode it........

i mean when i give the input in textbox and when i press search button.. it must list the corresponding details...........

please help me out... or do u hve any sample programs of this kind...

You haven't made it clear exactly what the user is entering in the text box. If it's an element name, you can replace

customername

by

*[name()=$param]
