Question

我想将我的谷歌浏览器书签放到数据库中，所以我的第一步是从Chrome中使用chrome导出.html文件并将数据转换为变量，我希望得到一些能够获得的PHP代码运行下面的数据，它将URL，ADD_DATE，ICON和链接文本全部提取到自己的变量中。

我知道我需要使用一些正则表达式，有人可以帮忙吗？谢谢，我会在时间允许的情况下为此添加赏金。

我喜欢用户yc建议使用类似这样的东西而不是正则表达式

$s = '<A HREF="http://snipt.net/public/tag/css"

$bookmarks = simplexml_load_string($s2);
echo $bookmarks["HREF"]; //URL
echo '<br>';
echo $bookmarks[0]; //Name
echo '<br>'; 
echo $bookmarks['ICON']; //Icon
echo '<br>'; 
echo $bookmarks['ADD_DATE']; //Add_Date

但是我还没想出如何让它在html页面或字符串上使用多个链接。

然后我找到了这个PHP DOMDocument类，我似乎让它像这样......

Answer 1

请勿使用regex，因为即使Chrome提供的HTML也不是常用语言。

使用XML解析器，例如SimpleXML。

如果上面的字符串是$s，

$bookmarks = simplexml_load_string($s);

echo $bookmarks["HREF"]; //URL
echo $bookmarks[0]; //Name

object（SimpleXMLElement）＃1（2）{ [ “@属性”] =＆GT; array（3）{ [ “HREF”] =＆GT;串（31） “http://snipt.net/public/tag/css” [ “ADD_DATE”] =＆GT; string（10）“1271801059” [ “ICON”] =＆GT;字符串（1026） “data：image / png; base64，iVBh .... =”} [0] =＆GT; string（64）“Snipt - public - css |共享和存储代码或命令片段。“}

Answer 2

一般来说，这个基于PHP的html数据提取教程可能会对你有所帮助：

http://www.matthewwatts.net/tutorials/php-tutorial-2-advanced-data-scraping-using-curl-and-xpath/

xpath绝对是值得精通的，如果你必须使用html或xml一般。 W3schools有很好的参考资料：

http://www.w3schools.com/xpath/default.asp

Answer 3

另一个选择（放弃PHP）是使用jQuery和CSS选择器。我更喜欢CSS选择器到xpath用于大多数目的，这种方法允许你利用精彩的SelectorGadget工具。

以下是最近的指南：http://blog.dtrejo.com/scraping-made-easy-with-jquery-and-selectorga
注意：它们链接到原始jQuerify。有一个actively maintained jQuerify Chrome extension和一个newer, better jQuerify。
