例如,我有这种超文本幻灯:
<a href="/sites/all/themes/code.php">some text</a>
问题在于:如何将案文<代码>/sites/all/themes/code.php从href与preg_replace(<> ;哪些模式我可以使用?
模式:
(<a .*?href=")([^"]*)
替换:1美元
我强烈建议,不要使用经常表达来 par任何SGML衍生工具。
供超文本使用时使用一些DOM教区。 具体来说,PHP有DOMDocument。
页: 1
(?<=<a href=")[^"]*(?=">)
带你直接想要的东西。
test鱼试验:
kent$ echo <a href="/sites/all/themes/code.php">some text</a> |grep -oP (?<=<a href=")[^"]*(?=">)
/sites/all/themes/code.php
