Can you parse out XML data in FileMaker Pro in one step?

If you regularly have to work with XML formatted data in FileMaker Pro®, getting the relevant parts of that data, and putting it into text fields can be a daunting task.
And you would probably say it is impossible to get a node of the XML out in one step as it would need a lot of script steps. But that is not the case if you use a plug-in.

Yes, it can be done!

It can be done if you install Troi Text Plug-in. This plug-in adds a function TrText_XML( ) to your arsenal of tools.
This function allows you to easily parse out a node from XML in one step! Here is the syntax of this function:
TrText_XML ("-GetNode"  ; Node_to_get ; XML_data )
The function has three parameters: the first parameter specifies the action to take, in this case to get a node from the XML. The second parameter specifies which node you want to get. Finally the third parameter is the XML data you want to parse.

Receive data from an external device in FileMaker Pro

With Troi Serial Plug-in you can receive data sent from an external device with a serial (RS232) interface in FileMaker Pro. You can have the plug-in start a script upon receiving in order to process the received data in your database.

Receiving the data

Assume you have an external serial device connected to a (virtual) serial port on your computer. You can use a serial-USB adapter to connect to a USB port on your computer, which will then act as a virtual serial port.

To receive data from this device, first open the (virtual) serial port on your computer using the Serial_Open function. Add this script step to a ScriptMaker script:
Set Variable[ $ErrorCode; Serial_Open( "-Unused"; "COM1"; ) ]
This will open the COM1 port.

Selecting Files in FileMaker

With Troi File Plug-in you can easily let a user select a file on disk, for example to get the contents into filemaker. With the plug-in you can also move or rename it, to indicate the file has been handled.

Selecting the file

Use the TrFile_SelectFileDialog function to open up a dialog which lets the user select a file. By default all the files can be selected. If you want the user to be able to select only files with a certain extension use the TrFile_SetDefaultType function first.

To let the user select any file add these script steps to a ScriptMaker script:
Set Variable [$DontCare; TrFile_SetDefaultType( "-Unused"; "")] Set Variable [$FilePath; TrFile_SelectFileDialog( "-Unused"  ; "Please select a file.") ]
This will return the path to the file for example:
MacHD:Users:John:Documents:FinancialReport2014.xlsx
