[Res] DataSoruce with mandatory and non mandatory fields

Hello Michael,

In your groovy snippet, I did not completely understand what the following parts do.

// set default value here
def defaultVal = ""

for( item in holder.getDomNodes( "//*[. = '']" )){
holder.removeDomNodes("//"+item.nodeName)
}


1) Where is the defaultVal used?
2) I understood that in the for loop, you are getting an array of nodes into the holder and you are trying to remove the nodes. But I am not clear about what the Xpath mentioned in the for loop ( "//*[. = '']" ) is and ("//"+item.nodeName)?
