Oliver Strässer updated CLEREZZA-29:
------------------------------------
Priority: Critical (was: Major)
Description:
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
