Is better to load 10 xml files than 1 bigger using Jquery/Ajax?

[Gzk2010]

1. I am a newbie, and from my understanding since ajax is loading in parts, you should breaks the parts down.
My page has 20 little chapters with story with 20 illustrations. So correct me if I am wrong, if I just make my 1 working xml file with 20 image references and the chapter text into lets say 10. It will load it asynchr xml file 1 to 10(with 2 chapters and images per xml files)?

2. So if my approach is correct which is the first I ask,
then I would need 10 different jQuery/AJAX calls like? Note the 1.,2.,3.,4. below are NOT part of the code, please ignore them, they are line numbers I cannot get rid of.

1.$.ajax({

type:

"GET"
,
url:



"chapters_1_2.xml"
,
dataType:


"xml",
2....
3.$.ajax({

type:

"GET"
,
url:



4."chapters_3_4.xml"
,
dataType:



"xml"
,



...etc. Is there a way to simply write ?
1.2.url: "chapters_1_2.xml,chapters_3_4.xml,chapters_5_6.xml,chapters_7_8.xml",

ect til chapters_19_20. And my questions does anyone know for sure that the above Ajax method will understand to load first file at a time, 1 at a time?
