Usually Multiselector doesn't have "all" option value..If it happens then then it's better to set value as "All" if <select> tag is defined in one form page and we render the value to some another page or multiple pages.If we defined it in same page and get on same page then we must have to define the value at declaration time.
Now if we get the value from "Select tag" then the value we are getting like this:
"val1 val2 val3"
and this single must be tokenised to iereate over multiple option values by two approach:
1.Using blank space " "
2.similar string patern.
First approach: (Best approach)
It is safe to use first approach if option string values doesn't have multiple sapces.Therefore try to avoid spaces in option values at definition time till it is not compulsary ( by normalising/trimming/removing spaces see difference in another blog for all three terms ) so that we can easily tokenized by using this approach since after each value there is a space val1 val2 val3 etc.
Second approach:
If it is complulsary to havaing spaces in string and string have some business pattern like (exporting each pdf or xml has an extension .pdf or .xml) therefore we can tokenize over each value as:
for ex- let $All := "0001012-0000002-KOMMUNEKREDIT.xml 0001012-0000003 KOMMUNE KREDIT.xml"
for $Each at $pos in fn:tokenize($All,".xml")[1 to fn:last()-1]
let $EachBatch := fn:normalize-space(fn:concat($Each,".xml"))
return $EachBatch
and then we also need to concat the value over which each string is tokenised.Here we run the loop to the second last element otherwise result would come as: >
0001012-0000002-KOMMUNEKREDIT.xml
0001012-0000003-KOMMUNE KREDIT.xml
.xml
there fore we skip last element.
Third Approach (Only used in following situation)
But what happens if we have compulsion to have spaces in option values and string doesn't have patterns then we have to append some tag identofire with each option value at declaration time or rendered time to differntiate multiple values.
