It's on of these things you should do in 5 minutes with one and but I always have troubles with regular expresions.
| Code: | {assign var=temp value=$a.description|regex_replace:"/*ABC/":" "}
{assign var=temp value=$temp|regex_replace:"/[/n]*/":" "}
{$temp} |
I think code above says it all. Question is how should first line look because *ABC removes everything. |

the first one isn't valid regex? (can't start with *)
and your second one is replacing any character that is / or n unlimited times?[/i] |

/.*ABC/ replace with ""
/\n.*/ replace with "\n" |

Thanks
| Code: | {if substr_count($a.description,"ABC")}
{assign var=temp value=$a.description|regex_replace:"/.*ABC/":""}
{assign var=tempb value=$temp|regex_replace:"/\n.*/":""}
{$tempb} |
It looks like first one don't work and after seconf regex I get first line from description not part of second like I would like. |

the "." does not include newlines by default. If you want to include those, you need the /s modifier. see the PCRE manual for examples of how to use regular expressions.
Also, you could build yourself a plugin and do all your regex work in PHP instead of in-template, if that helps. |
