Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 2018b b9.5.5.409
Operating System: Win 10 64-bit
I would like to import an XML file as a tree variable in Labtalk but I'm not able to access the tree variable I've made with an Origin C function. I have created the following Origin C function to import the XML:
void XML_load(string filename)
{
Tree trLoad(filename);
}
I can compile this code successfully and can run the C function in Labtalk with the following Labtalk script:
XML_load("C:\\Test.xml")
I would like to access the new tree variable "trLoad" in Labtalk but haven't any success. I'm new to programming (i.e., object oriented programming, etc.) which explains my difficulties with this relatively easy task. Please help.
Thanks! |

I think I have it now. The Origin C function should look like this:
void XML_load(string filename, string treename)
{
Tree trLoad(filename);
Project.AddTree(treename, trLoad);
}
where treename is the name of my new project level Labtalk tree and filename is the XML file I wish to import.
Then my Labtalk script would look like this:
XML_load("C:\\Test.xml", "NameOfMyLabtalkNewTree") |

Thanks Chris!
So would my new Origin C function look like this?
void XML_load(string filename)
{
Tree trLoad(filename);
int TestTree = Project.AddTree(trLoad);
}
I must not have a clear understanding with Project.AddTree because I'm getting compile errors with the above function :( |

Hi,
You may use Project::AddTree within your Origin C function to create a project-level Tree variable accessible from LabTalk using the name you assign the Tree to.
See:
https://www.originlab.com/doc/OriginC/ref/Project-AddTree
I'm not sure how well LabTalk will be able to deal with your particular XML though.
Note: it IS a project level variable and will be saved with the project. But this way works to get you the Tree.
I hope this helps!
Thanks,
