 Posted: Tue Dec 23, 2008 10:14 am Post subject: regex_replace ersetzt nur letzten Match |
 |
|
Hi,
ich bin auch relativ neu was den Umgang mit Smarty-Templates angeht, deswegen gleich zu Anfang mal eine Frage:
Ich habe diesen Ausdruck geschrieben, der in einem mehrzeiligen Text den Part, der zwischen zwei Rauten steht, verlinken soll. Hier mein Ansatz:
| Code: | | {$text|regex_replace:'/^(.*)#(.*)#(.*)$/':'\\1<a href="link.html">\\2</a>\\3'} |
Leider, leider gibt es im Text zwei in Rauten eingefasste Stellen, die verlinkt werden sollen, und der Reguläre Ausdruck ersetzt immer nur die letzte.
Nur ungern würde ich den Regulären Ausdruck so abändern, dass er immer exakt zwei Vorkommnisse von #Link# erwartet. Eigentlich sollte regex_replace doch immer alle Matches des regulären Ausdrucks ersetzen?
Wo liegt der Fehler?
Freundliche Grüße
Niehztog |

Versuch mal den Modifier m:
| Quote: | m (PCRE_MULTILINE)
By default, PCRE treats the subject string as consisting of a single "line" of characters (even if it actually contains several newlines). The "start of line" metacharacter (^) matches only at the start of the string, while the "end of line" metacharacter ($) matches only at the end of the string, or before a terminating newline (unless D modifier is set). This is the same as Perl. When this modifier is set, the "start of line" and "end of line" constructs match immediately following or immediately before any newline in the subject string, respectively, as well as at the very start and end. This is equivalent to Perl's /m modifier. If there are no "\n" characters in a subject string, or no occurrences of ^ or $ in a pattern, setting this modifier has no effect. |

| Funktioniert leider nicht, zumal in dem Text auch keine Zeilenumbrüche drin sind (wird ja in HTML Darstellung automatisch umgebrochen). |

| (.*) Ist per default greedy, also matched #(.*)# alles von der ersten bis zur letzten Raute (inkl. aller Rauten). du willst wahrscheinlich #(.*?)# - also non-greedy Matching. |
