problem open xml file

[micky71]

Hi, i'm using labview as beginner in labview application. I started to load and interpreter a simple xml file with labview and classical VIs object for xml treatment. I realized my project, i found the nodes correctly, but i have a problem to extract the child and sibling elements of a node. Could anyone suggest me ho to extract a list(sibling) of childs from a node? 

So i have to search if exist a block to open a file with a scheme. In labview i think it doesn't exist, correctly?

Thanks Michele

Please try to share the XML File you use and the Code Snippet which you tried.
Use XML Grid and check whether your file has proper schema?

Thanks for the answer, in the attach there is a simple project to load the file "tabellismo_simple". The problem is to find the instance array of "classe" nodes.  There is the file scheme, thank you Michele

Please share the Vi with LV2015 and the expected data from the shared file.

In the attach i post the project with labview 2015.

With NodeChildsArray, i'll expected (or i would) to find an array of instances from node rele 

<classe nome="RELE">
<istanza ist="0" nomeMnemonico="Caldaia 1apre">

<istanza ist="1" nomeMnemonico="Caldaia 1chiude">

...

instead it doesn't return the child array correctly

thanks Michele

Try like the same for ist and nomeMnemonico

[PalanivelThiruvenkadam]

Xpath For nomeMnemonico     "/impianto/classe/istanza/@nomeMnemonico"

Xpath For ist    "/impianto/classe/istanza/@ist"

which will give all Values irrespective of Classe Name so make Loops in such a way Classe values are extracted.

Thanks for the answer and i'm sorry about delay for my reply but i was to make core2 course, i had done this, but my problem is to search various children from single class. In your example i couldn't find the addiction of children instance from the parent node. In your example or in my i have to find a list of class children from various node, then i would extract the attributes from the various instance. Your sincerely Michele

You need to use your xpath in such a way you expect the output.
