Question

I Have Text in the middle of <b></b> Eg:

La  <b>la</b>: the  1  <br></br>Aventuroj  <b>aventuro</b>: adventure  2  <br></br>de  <b>de</b>: by, from, of, since  3  <br></br>Mirlando  <b>miri</b>: marvel, marvel at, wonder<br/><b>lando</b>: country, land  4  <br></br>by  <b>ba</b>: bah, nuts, pooh  5  <br></br>for  <b>for</b>: away  6  <br></br>

I would like maybe a regex that would strip the text and the <b></b> from the string

Thanks

Answer 1

The simplest way is to use preg_replace():

$output = preg_replace('!<b>.*?</b>!s', '', $input);

The s on the end is a flag. See Pattern Modifiers for a list of flags.

s (PCRE_DOTALL)

If this modifier is set, a dot metacharacter in the pattern matches all characters, including newlines. Without it, newlines are excluded. This modifier is equivalent to Perl's /s modifier. A negative class such as [^a] always matches a newline character, independent of the setting of this modifier.

Generally speaking however regexes are a poor tool for querying and manipulating HTML or XML. PHP has a number of inbuilt HTML parsers and for a robust solution you should use those instead, as a general rule.
