Inputs/Outputs

  • cpath.png XML File Path —

    XML File Path is the path and filename from which you want to read XML data.

    When you specify an empty path, a dialog box prompts the user to specify an XML file.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • ipath.png XML File Path(duplicate) —

    XML File Path(duplicate) is the path of the file from which the VI reads data.

    You can use this output to determine the file path that you selected through a dialog box. XML File Path(duplicate) has a value of <Not A Path> if you cancelled the dialog box.

  • istr.png XML Elements —

    XML Elements returns the top-level XML tags found between the end of the </Version> and </LVData> tags in a single string. You then can wire this output to the Unflatten From XML function.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
