XML text node

[CyGa]

Hi!
In my application, I want to use XML files as configuration files.
I made a VI using XML DOM Parser fonctions to fill the text nodes with the desired information. In the case I want to overwrite previous information stored in a node , the data has to be written as text and is placed between the corresponding markers (for exemple in the attached file <InputValue>data<\InputValue>).
However if a node is empty (no text previoulsy written), the marker becomes <InputValue/>. In that case, it is impossible to write data in it... Why is that ?

I think my code is more explicit... Launch Test.vi, you will notice that the nodes "S_DateHeureFin" and "S_NomEquipementFin" are never written if they are empty (but they can be overwritten if a text is already present when the Vi is launched).

Note : I couldn't attach XML file so I changed the extension into jpg , so you have to change the extension .jpg to .xml of Try.jpg to read my xml file...

Two things:

1. <InputValue/> is an empty node. This is XML-Standard and you have to deal with when writing your own VIs.

2. Why haven't you used the XML-Functions built into LabVIEW? Just connect anything to it and you will get the XML-String. If you have several clusters just make an array of them and write it to / read it from a file using the XML-File functions.

Using the built-in XML functions is a good idea, though they are somewhat limited.

Another option is to use LabXML, rather than spinning your own XML read/write functions.

In this case, you have to create a new text node, and then append it to the element node.
