如果无法将页面的标记内容解析为XML，该如何获取该页面的标记的内容？

I'm using PHP libcurl to load a page. Now I need to get this page's <title> tag's content, and some other information too. I've tried to parse it using SimpleXML, but with no luck, because the page isn't valid XML. Can you suggest some other way to easily get contents of <title> tag? Thank you.
