原标题:Find and Replace with QueryPath

我为$output 变量指定了一个字符串。 我想使用 QueryPath 通过字符串循环, 并在每个匹配元素中添加一个类 。

目前,我已:

$output = qp( $output) - & gt; findd( 表) - & gt; addclass (表) - & gt; html ();

唯一的问题是它在第一次比赛前删除了 $output 的内容 。 是否有一种方法可以使用 QueryPath 来找到匹配, 然后添加类别, 同时保持$utput 的内容完整?

编辑:

Pseudo code:

$output =  <table class="temp"><blah></blah></table> ;

Magic QueryPath

$output =  <table class="temp blah"><blah></blah></table> ;
问题回答

尝试删除 < 加强> html ()

$output = qp($output)->find( table )->addclass( table );

用于显示 :

$output->writeHTML();

html():: Replaces the child content of the current element or elements in an HTML document
