PArsing XML error

[M_AmineJ]

HEllo Everyone,

I need to use XML to save some program data. In the attached example, I am saving a path to an XML file, so that my program remembers the latest Export folder used.

The format of this simple XML file is as follow:

<?xml version="1.0" encoding="UTF-8"?>
-<Config>
<ExportFolder>C:\Users\AJ\Desktop</ExportFolder>
</Config>

At some other point in my main program, an exception occurs when trying to update the XML file with a new  path location and i endup with the current XML :

<?xml version="1.0" encoding="UTF-8"?>
-<Config>
<ExportFolder/>
</Config>

I am currently trying to detect if the ExportFolder text node is empty then add a default path to it :

The if statement is working but I can't find a way to update the XML file and parse a next node under the ExportFolder Element.

Any help will be greatly appreciated.

Best regards,

AJ

Not sure where the exportFolder text node is in your app, but cant you use the empty string? vi and if true wire a default path.  You can use hte select? vi if you dont want to use a case structure for this.  There is also a is path and not empty? vi if you node is a path.

Hello Matt,

I am indeed trying to " you use the empty string? vi and if true wire a default path."

My problem is that I can't append the closed tag with the new path.

Once this tag is closed :

<ExportFolder/>

I can't find a way to programmatically change it back to :

<ExportFolder>C:\</ExportFolder>
