Difference between replace entire node and replace node contents in OSB -

i have started using osb , came across feature "replace entire node or replace node contents". me in listing out difference between 2 examples. basic question started learning osb , wanted right.

thanks in advance.

cheers..

ok, let's assume have variable, $body. proxy has done stuff, , has $body set, , want run through xquery transform before return it.

$body like

<soap:body xmlns:soap="etc">   <ns0:response xmlns:ns0="etc2">     <ns0:item>       <!-- etc etc -->     </ns0:item>   </ns0:response> </soap:body> 

if replace entire node, must replace <soap:body>. (i mean, could replace different, you'll encounter error somewhere because osb expects $body type)

if replace node contents, may replace anything: perhaps transformed <ns0:response>, it's common replace totally different elements. either way, <soap:body> element unaffected, , insides scooped out , replaced.

most of time, you'll replace node contents of $body rather replacing entire node, if it's variable you've created yourself, go either way depending on want.
