Php Solutions

Solution 1 - Php

g is implicit with preg_replace(). You don't need to include it.

Solution 2 - Php

You don't have to specify the global flag. From the documentation, there is a separate parameter ($limit) used to specify the number of replacements to make:

> limit > The maximum possible replacements for each pattern in each subject string. Defaults to -1 (no limit).

So, unless you specify a positive number for this parameter, it will replace all occurrences by default:

$strTmp = preg_replace('~(<\/CharacterStyleRange>(.*?)\n*</CharacterStyleRange>)~im ' , "</CharacterStyleRange>", $strTmp);

Solution 3 - Php

There is a / before the letter G in the string you're replacing.
