Re: dynamic reference

Hi Daniel,

thanks a lot for the answer

the thing is a bit mor complicated, i try to explain... :-)

i have this xml structure


<book title="Test" author="einstein" number="4711" />



i need to access the attributes, the problem is, the attributes are very dynamic, so i don't know the names
i cann access the title of the book by doing: ${book.@title}

BUT the name of the attribute, here "title" is unknown
what i have is a separate list, where the names of attributes are stored, called "attr"

now i want to iterate over all velues of attributes defined in that list
is that possible?

should look like that, but this does not work

<#list attr as a>
  ${book.@[a][0]!"undefined"}
</#list>

i hope, the question is clear

regards
andre
