Question

我在PHP函数中有以下字符串（$ line）。

$line='<span class="cooktime">25 Mins<span class="value-title" title="PT0H25M"></span></span><span class="preptime">30 Mins<span class="value-title" title="PT0H30M"></span></span>';

我想使用preg_replace或任何其他方法将每个跨度集转换为以下内容：

$line='<span class="cooktime">25 Mins<span class="value-title" itemprop="cookTime" content="PT0H25M"></span></span><span class="preptime">30 Mins<span class="value-title" itemprop="prepTime" title="PT0H30M"></span></span>';

基本上我将itemprop属性添加到span块并将title属性重命名为content。

我如何实现这一目标？

感谢您的时间，JK

Answer 1

可以尝试这样的事吗？（没有在PHP中测试，但是使用JavaScript测试了RegEx，它似乎有用。）

preg_replace("^(.+)title(.+)$","$1itemprop=\"prepTime\" content$2",$line);

Answer 2

尝试使用：

$str = '<span class="cooktime">25 Mins<span class="value-title" title="PT0H25M"></span></span>';
$str = preg_replace('/" title="/', '" itemprop="prepTime" content="', $str);
echo $str,"\n";

<强>输出：

<span class="cooktime">25 Mins<span class="value-title" itemprop="prepTime" content="PT0H25M"></span></span>

Answer 3

好的 - 我找到了答案。感谢Andrew＆amp; M42给出了想法。这是：

$line = preg_replace('/\ (.*?)class="preptime"(.*?)<span class="value-title" title(.*?)/i','$1class="preptime"$2<span class="value-title" itemprop="prepTime" content$3',$line);
$line = preg_replace('/\ (.*?)class="cooktime"(.*?)<span class="value-title" title(.*?)/i','$1class="cooktime"$2<span class="value-title" itemprop="cookTime" content$3',$line);
