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 1
line 2
line 3
line 4
How could I build the textual part also considering the empty node?
I would to obtain:
Line 1
line 2
line 3
line 4

EDIT
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:

I’d need an XPath expression that selects p, h1, h2,…, h6, li elements, and considers the inner textual part in such way that new line and empty lines are properly detected.
For the example above you can use
//spanwhich will return all the<span>elements regardless of their contents. It looks like you are doing some other filtering also because //text() should also return your CSS block andA Titlefrom the<title>and first<span>.
