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 {""}}
