我正在学习 RSS 解析——事实上我对它很陌生。我想知道在 php 中接收 RSS 提要的概念。但随后使用该项目的 RSS 链接转到新页面，然后解析该页面以查找与其关联的图像（假设图像编号不同，但后续页面上的 html 没有）
这样的事情可能吗？没关系，我不要求您提供细节/为我做这件事。只是对这个概念进行一些简短的教育。
比如说这个网站： http ://www.bulettings.com/
它有一个 RSS 源： http ://www.bulettings.com/propertyrss
对每个项目说：

我得到了这些信息，但随后我说“转到”，这会将我带到一个页面，其中来源是：
<script type="text/javascript">
if(document.images){
currentphoto=1;
maxphotos=7;
photo = new Array(7);
Imagetext = new Array(7);
photo[1]=new Image();

因此，它会从 rss 中获取该信息以及有关它的信息，将其放在某个地方并删除所有垃圾，然后将其与图像链接一起保留。然后继续下一个项目。
可以这样做吗？
