You can specify the source XML file for conversion in the properties window for the XSLT file. The input property must contain the path to the XML file being processed. Enter the path to the new XML file here.
An XSLT transformation can process more than one XML document at a time .
This is achieved by using the document() function or by passing an XML document as a parameter for conversion .
You might need to enable the document() function using the XsltSettings.EnableDocumentFunction property.
