Writes a text string of XML data with accompanying header tags to a text file. The data type you wire to XML Input determines the polymorphic instance to use.

Example

Use the pull-down menu to select an instance of this VI.

Write to XML File (string)

	XML File Path is the path and filename to which you want to write XML data. The file name must have a .xml extension. When you specify an empty path, a dialog box prompts the user to specify an XML file.
	XML Input contains XML data to write to the file.
	XML Encoding specifies the encoding scheme for the XML file. LabVIEW supports ANSI and Multibyte encoding schemes.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	Standalone? specifies the value for the standalone attribute in the XML declaration. Standalone? determines whether the document exists entirely on its own (TRUE), or depends on other files (FALSE).
	XML File Path(duplicate) is the path of the file to which the VI writes 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 canceled the dialog box.
	XML String contains the XML data that the VI writes to the specified file.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.

Write to XML File (array)

	XML File Path is the path and filename to which you want to write XML data. The file name must have a .xml extension. When you specify an empty path, a dialog box prompts the user to specify an XML file.
	XML Input allows you to write multiple nodes of XML data to an XML file.
	XML Encoding specifies the encoding scheme for the XML file. LabVIEW supports ANSI and Multibyte encoding schemes.

If an error occurred before this VI or function runs, the VI or function passes the error in value to error out.
