[xml] record count and display

["Zichao Mao" <mzichao hotmail com>]

Hi,

I want to display 3 items in a page and when the user scolls down, another 3 
items is displayed.  Whenever the user selects a category, the stories with 
matching Category tag are returned and displayed.  The category is displayed 
3 stories at a time.  When the user scrolls down and wants access to 
additional stories from the category, another 3 stories are displayed.  The 
Count is used in the process and when it reaches 3, it will reset and get 
the next 3 stories. Does libxml2 have functions that can search and do that?
This is what I have, please tell me it's right or not:

if ((!xmlStrcmp(cur->name, (const xmlChar *)"business")))
        count++;
for(i=1;i<=count;i++)
{
contentData = xmlNodeListGetString(doc, cur->children, 1);
count--;
if (count % 3 == 0)
return;
}

How do I display the next 3 records?
Thank you.
