how to read XML file using Automatic ref No

[parthipan]

I need to get the data from the xml file using Automatic reference No.I am a beginner .help me out

Unfortunately I do not understand what you mean by "using Automatic reference No", since I have no idea what you are referring to. Can you please provide more information. Without anything more to go on I would suggest looking at LabXML as one method to read generic XML files.

Hi Parthipan,

An easy way to get started with using XML in LabVIEW is a toolkit called EasyXML -- it's a product from JKI that I helped create 🙂

Thanks,

Hi parthipan,

insert the Automation open vi into your vi and right click on the ActiveX Refnum input. Create a constant and select the type you need.

Hope it helps.

Hi muks,

           ya i tried it out but it is not suitable for my application.For my thing input is xml path it should create the automatic reference no.and automatic reference c;ass to access the data in the xml file suce as getting the nodes under  root parent node,attribute etc.

I see now. You are actually talking about the automation reference, not the "automatic reference no", which is meaningless. To access the XML file this way then you need to use ActiveX. Have you looked at LabXML? That uses ActiveX and you can look at all the code and see how it's done. It is pointless to try to do this from scratch as the XML spec, while not being excessively complicated, can be difficult for the beginner, as you clearly are. Therefore, it is best to try to use a set of functions that are pre-written for  your use.
