I receive an html like that below from a server. I rebuild the textual part by using the XPath exp @"//text()" and appending the "nodeContent" value to a string. The code is something like this:
for (int i=2; i<[resultXPathQuery count]; i++) { [mytext appendString:[[resultXPathQuery objectAtIndex:i] objectForKey:@"nodeContent"]]; [mytext appendString:@"\n"];}I obtain:
Line 1line 2line 3 line 4How could I build the textual part also considering the empty node?
I would to obtain:

Really, I noticed that the html can be more "complicated", so it's not enough selecting all the span elements or p elements. Moreover, more span elements can appear in the same p element, so in that case I have not to create a new line in my string.
This is the body of a more complicated returned html:
