ereg_replace

[Allnoch Gerlinde <Al...@Verwaltung.uni-hohenheim.de>]

Hello, 

 

i am looking for something like:

 

#set ($thema = ereg_replace('#  ', '', $thema))

#set ($thema = ereg_replace('# ', '', $thema))

#set ($thema = ereg_replace('#', '', $thema))

 

How is it possible to do this ?

If you are running on a JDK 1.4 VM try:

#set( $thema = $thema.replaceAll('# ? ?', '') )

Other regular expression patterns might be more suitable, but
this does the same as your three lines above...

See more on String.replaceAll and Pattern in the API docs at:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#replaceAll(java.lang.String,%20java.lang.String)
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html

You could pack this into a veloci-macro,
   #macro( ereg_replace $from $to $string )$string.replaceAll( $from, $to )#end
   ...
   #set( $thema = "#ereg_replace('#  ', '', $thema)" )
but IMHO the replaceAll is so straightforward packing it into
a macro is an overkill.

Cheers,
Christoph
