使用preg_split（）使用标签拆分文本

Question

I'm trying to split the following text:

<word>test</word><word>test2</word>

etc via the following reg ex:

preg_split(":</?word>:is", $html);

I get the result: test and test2 as the result, but what I need is to retrain the <word> and </word> tags, so instead of just test and test2, i get another 4 elements with the matching tags in them.

How can this be done?

First of all: use a parser to modify XML (something like SimpleXML of DOM could suit you fine, depending on the actions taken next).

However, for the sake of argument:

preg_split(":(</?word>):",
    "<word>test</word><word>test2</word>",
    0,
    PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);
