Usage: xsltproc lvstrings2input.xsl lvstrings.xml > lvinput.xml
lvstrings.xml is the output of
ExportVIStrings() from LabVIEW, but has also
been processed by the fix_xml.cmd script (as the raw output of
ExportVIStrings() is not valid XML)
To run
ExportVIStrings() interactively, go to "Tools -> Advanced -> Export Strings..." from the LabVIEW VI menu bar
@file lvstrings2input.xsl Process output of LabVIEW
ExportVIStrings() to generate an XML configuration file for lvDCOM
