[jira] Resolved: (CLEREZZA-29) Wish for Scala function

["Reto Bachmann-Gmür (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CLEREZZA-29?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reto Bachmann-Gmür resolved CLEREZZA-29.
----------------------------------------

    Resolution: Fixed

Implemented version in which an non-existent property appears as if empty  simple literal. I doubt that's the right place to do any xhtml validation: only xhtml literals should be integrated in xhtml output without escaping, if the output is not xhtml then invalid xml isn't a problem.

> can you provide a funtion in scala wich checks a given property, and if the property is set, the return value is the string representation of this property. 
> if the value isn't set, the returnvalue is an "" string .
> i don't want to wrote everytime the folloeing code: 
>  
> {if((res/DC.title).length > 0){res/dc("title")*}else {""}}
>  
> or : 
>  
> {if((res/dc("description")).length > 0){XML.loadString(res/dc("description")*)}else {""}}
> To Functions (One for XML and one for normal String is ok)
> Better is: 
> {if((res/acp("statusTextForParticipants")).length > 0){
>                                     try {
>                                     XML.loadString(res/acp("statusTextForParticipants")*)
>                                     } catch {
>                                     case e:Exception => res/acp("statusTextForParticipants")*;
>                                     }
>                                     }else {""}}
> or an functionm wich generates valid xml from string (escaped / not escaped // is an xmlliteral or not)
> , when the string is copied from microsoft word, like this. Hard to explain. 
> THIS IS VERY IMPORTANT, BECAUSE YOU CAN'T RELY  ON THAT THE USER GENERATE VALID XML CONTENT
