Question

I could not think of a proper title. I have some data like –

$data = <<<EOD
<strong>
HHHHH
<strong>
TTTTT
<strong>
RRRRRRR
<strong>
EOD;

Basically above one is just an example. In real, the data is like –

<strong>Some Title</strong>
DATA
<strong>Some other Title</strong>
OTHER DATA

Sample: http://pastebin.com/cxzZWDZ8

Now I apply the following RegEx.

preg_match_all("%<strong>(.*?)<strong>%s", $data, $all);

This matches, HHHHH and RRRRRRR but I want to match TTTTT. How can I do this?

Answer 1

You could use a lookahead assertion to ensure the <strong> is there, but isn’t part of the match (so it can be part of the next match):

</strong>(.*?)(?=<strong>)

However, if what you’ve got is HTML, you should use an HTML parser to read it and not regex which is infamously poor at parsing HTML/XML markup. With DOMDocument::loadHTML(), getElementsByName and so on you’ll have a much more reliable way of scraping page data.
