房价貌似快要涨了,俺最近天天加班,俺媳妇来负责找房源,可她那狗屎公司无法上网,只好用ipad 加载rss 离线看,结果狗屎sohu焦点的rss 非全文rss ,为了老婆找房方便,写了点代码,用于生成全文的rss. 希望借此机会,尝试一下代码改善生活的感觉. 不废话吧，直接贴代码了.

header("Content-type: text/html; charset=utf-8");

ini_set("max_excution_time"  ,3600);

$url = "http://sz.focus.cn/common/xml/rss/news/hot.php";



$newItemArr = parseItems( $url );

$xmlItemContent = makeRssItemString( $newItemArr ); //重新生成item 内容,将下载内容替换descript.



//rss xml 的头尾字符串

$xmlPre = '










xmlns:focus="http://house.focus.cn"

xmlns:F="http://house.focus.cn"

docType="rss"

F:docType="rss"

>


pageIndex=""

pageSize="20"
