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)
