Re: RESOLVED - Building Web Services with GXML

Wow Martin I'm glad you called tech support.  I don't think I would have figured that out.  Thank you for posting the resolution!  I have several projects in the pipe that will use GXML in a LabVIEW Web Service.

GXML does not work with tables

[ Edited ]

The GXML parser does not seem to work with tables such as an array of clusters containing one string and one table does not work.

Re: GXML does not work with tables

Could you please attach an example VI demonstrating this?

 

Thanks,

Fast Parser does not work with arrays of unknown size

I have a large data structure (array[(string,array[][])]) that takes around 1 minute to do a recursive parse on an cRIO.  The fast parse mode

gives me an error because the array sizes are not known at runtime.  Is there a way to make the fast parse mode

work in such a case?

Re: Fast Parser does not work with arrays of unknown size

Actually the problem is that the GXML data that is being generated and saved to the cRIO Flash is somehow getting its <cr><lf>'s messed up.  I will have to revisit in the morning and will post my results.

Re: Fast Parser does not work with arrays of unknown size

Ok, the problem was in the read/write file.vi primitive that I use to save and read the GXML data from my target devices.  The default for the file vi's is to convert EOL to LF which makes the data incompatible with the GXML parser.

Re: Fast Parser does not work with arrays of unknown size

Are you using the the GXML Read/Write File VIs?
