I am designing a website for someone at the moment and they want a preview of thier wordpress blog on thier home page(not blog home page)

Is there a good way to do this automatically so that it updates itself whenever a new blog is posted or will it be a lot easier to just do it manually?

I have a completly free reign over what languages and how the home page will be coded.

Any help greatly appreciated.

just parse the xml from the rss feed...

        $parser = xml_parser_create();
        xml_parse_into_struct($parser, $feedeed, $valueals, $index);
        xml_parser_free($parser);
 
	//CONSTRUCT ARRAY
        foreach($valueals as $keyey => $valueal){
            if($valueal['type'] != 'cdata') {
                $item[$keyey] = $valueal;
			}
        }
 
        $i = 0;
 
        foreach($item as $key => $value){
 
            if($value['type'] == 'open') {

                $item = $itemame[$i];
                $i--;
