Hi,

I would like to replace some text found in a particular div tag.

I managed to do this myself but had some limitations - cannot replace data found in a div tag when it is enclosed in another tag. eg: <div id="replace"><strong>5336</strong></div>

If the <strong> tag was not there the below php function would have replaced the content with $appendContent.
$newContent = preg_replace('#<div id="replace">[^<]*</div>#', '<div id="replace">'.$appendContent."</div>", $oldContent);

Open in new window

Why not just simplify the test?


$newContent = preg_replace('#<div id="replace">(.+)</div>#', '<div id="replace">'.$appendContent."</div>", $oldContent);

The dot (.) means "any character", the plus means "one or more times" so .+ means any character occurring 1 or more times.  Regular expressions can be highly complex and difficult to read or set up. Keep them as basic and simple as possible. Start with these articles
