Hello! The thing here is that the value is never a DOM node. Hence my question. I previousley asked why the "assign location" didn´t call for the "set" function in the Context and got the answere that the "assign location" doesn´t work as "assign name", "assign name" calls the set function and sets a variable, "assign location" manipulates the XML tree as it is. The advice was to make an "custom action" instead or do the ugly hack I did: do an "assign name" with the name after the "assign location" has executed. What I wanted to know is if there is any way of fetching the "tree" or whatever it is to get the data associatet to a name, according to the model below. If you look at my example below, I will always "know" the name of the datamodel in this case: "DynamicData", and I will recieve the "name" of the specific tag in this data, in this case "Data_1", "Data_2" or "Data_3". In my model below I have done an ugly way of finding out what the value is but i realized that that was not enough, i need to know the "type" aswell. And that I don´t know how to find.
Does anybody have a solution to this, or some kind of idea on how to solve this? best regards //Linda On Tue, May 5, 2009 at 3:50 PM, Ingmar Kliche <[email protected]>wrote: > Linda, > you should be able to use the DOM API to read the values.
