一段简单的正则,请教

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$content = 
  • html;$parr = "/href=\"\/html5\/(.*)\"/i";preg_match_all($parr, $content, $result);var_dump($result);
    匹配到的结果如下 
    string(30) "tag_comment.asp" title="HTML 5"
    string(15) "tag_doctype.asp"

    第一个还包含了 title 属性。 我的本意是只取href属性的值,该怎么做?

    ------解决方案--------------------
    $parr = "/href=\"\/html5\/(.*?)\"/i";



    array(2) {
    [0]=>
    array(2) {
    [0]=>
    string(29) "href="/html5/tag_comment.asp""
    [1]=>
    string(29) "href="/html5/tag_doctype.asp""
    }
    [1]=>
    array(2) {
    [0]=>
    string(15) "tag_comment.asp"
    [1]=>
    string(15) "tag_doctype.asp"
    }
    }

    ------解决方案--------------------
    我一直用这个,忘了从哪里找的了。反正我是看不懂,只管用
    PHP code
    '/<a.>(.+?)/sim'<div class="clear">
                     
                  
                  
            
                </div></a.>

    html5废弃了dir列表标签。dir标签被用来定义目录列表,一般和li标签配合使用,在dir标签对中通过li标签来设置列表项,语法“<dir><li>列表项值</li>...</dir>”。HTML5已经不支持dir,可使用ul标签取代。

    mPDF

    mPDF

    mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
